Greenhouses",subtitle:null,reviewType:"peer-reviewed",abstract:"\r\n\tGreenhouse cultivation has evolved from simple covered rows of open-fields crops to highly sophisticated controlled environment agriculture facilities that projected the image of plant factories for urban agriculture. The advances and improvements in greenhouse technology have promoted scientific solutions for the efficient production of plants in populated cities and multi-story buildings. Successful deployment of high-tech greenhouses for urban agriculture requires many components and subsystems, as well as the understanding of the external influencing factors that should be systematically considered and integrated.
\r\n\r\n\tThis book project aims to highlight some of the most recent advances in modern greenhouse technology for food security and the sustainability of crop production. Each chapter is expected to raise the awareness for technology transfer in advanced controlled environment agriculture, which is necessary for a successful transition to urban agriculture. Contributing chapters will highlight several aspects of a high-tech closed-field plant production system including improvements in the frame and covering materials, environment perception and data sharing, and advanced microclimate control and energy optimization models. In addition, the book will highlight urban agriculture and its derivatives, including vertical farming, rooftop greenhouses, and plant factories which are the extensions of CEA and have emerged as a response to the growing population, environmental degradation, and urbanization that are threatening food security. Finally, several opportunities and challenges will be identified as a summary chapter to show how integrated controlled environment agriculture can be implemented as vertical farming for urban agriculture.

Rotator cuff consists of four muscles supraspinatus, infraspinatus, teres minor and subscapularis. Subscapularis is largest of the four and is attached to the Lesser Tubercle. It constitutes 50–60% of the rotator cuff. It is one of the main anterior stabilizers of the shoulder.
The subscapularis muscle is the primary internal rotator of the shoulder joint. It also gives strong anterior stability along with capsulolabral tissues to prevent anterior dislocation. Recent studies have shown how the subscapularis works together with the infraspinatus muscle to create smooth balancing force couple and provides concentric compression effect.
Subscapularis tears are not as common as tears of the supraspinatus tendon. Subscapularis tendon tears may be isolated or in conjunction with supraspinatus and infraspinatus tendon tears or biceps tear/ subluxation (Figure 1).
Subscapularis anatomy.
Subscapularis tendon tears have been firstly described by Smith [1] and Codman [2] Hauser reported in 1954 the first case of surgical repair of the subscapularis tendon [3].
Subscapularis tendon tears may be partial or full thickness. Chronic overload or acute trauma may cause tears. Traumatic tears are usually secondary to a forced external rotation or extension of the shoulder with the arm abducted. These tears are more prevalent in young patients as a consequence of a shoulder dislocation [4, 5]. In chronic tears due to repeated micro trauma degeneration, there is always an associated supraspinatus tear and biceps tendinosis or subluxation along with subscapularis tear. In tears of long duration, there can be severe retraction of the tendon underneath coracoids process. Sometimes it get tucked to superior capsule or glenohumeral ligaments forming a “Coma sign/tissue” as described by Burkhart [6].
The main causes for subscapularis tear with or without other lesions is Sub coracoid impingement with reduced coracohumeral distance. Due to repeated friction in narrow canal beneath the coracoids process, attritional tear of subscapularis happens. When this distance, which normally ranges from 8.7 to 11 mm, is lower than 5 mm, the risk that the subscapularis tendon is torn is high [7, 8].
The coracoid impingement may be primary or acquired. Primary causes of sub coracoid impingement are lateralized coracoid process, calcifications or ossifications of the subscapularis tendon, subscapularis muscle hypertrophy, and ganglion cysts. Secondary causes are usually traumatic or degenerative like displaced humeral or scapular fractures, non-unions, posterior dislocation of the sternoclavicular joint, spur formation, etc., (Figure 2).
Coracoid impingement.
The subscapularis tendon is torn in 63% of patients in whom the biceps tendon is sub-luxated or dislocated as there is continuity between medial margin of pulley and the subscapularis tendon.
The shoulder pain related to a subscapularis tendon tear is more anterior compared to the typical pain observed in patients with rotator cuff tears. There is weakness in internal rotation and abduction like buttoning the shirt, adjusting the tie, tucking the shirt in the back etc. as these functions requires active internal rotation. Since in most of the cases anterior supraspinatus and biceps tendon is also involved, forward flexion, supination and abduction- external rotation can also be painful.
On examination there will be increased passive external rotation, Loss of active internal rotation strength.
Lift-off, belly-press, Napoleon and bear-hug are specific tests to assess the subscapularis tendon.
The lift-off test: This test has 15–20% sensitivity and almost 100% specificity (Barth et al.) [9]. This test is carried out in sitting or in standing position. The patient’s arm is kept in internal rotation with the hand is placed at the back at lumbar spine level. In this position patient tries to move the hand away from back by further extending arm and in internal rotation. Now if this movement is possible, examiner can check by providing resistance. The test is positive when the patient is unable to lift the hand away from back indicative of tear of subscapularis. The degree of weakness and pain are indicative of the degree of the lesion (Figure 3).
Lift off test.
The belly-press test: It is one of the most commonly performed and accurate clinical test for subscapularis tear with sensitivity of 40% and specificity of 97.3%.It is also called as abdominal compression test, In this test patient attempts to press the hand against the belly with the arm rotated internally [10].The examiner places hand on the abdomen so he can feel the how much pressure patient is applying. The test is considered positive if the pressing force is weaker or if the pressing movement of the hand against the belly is possible only with the elbow extension and shoulder extended. This indicates a deficiency of the subscapularis tendon tear or dysfunction (Figure 4).
Belly press test.
The Napoleon test: It is similar to belly press test also called as modified belly press test. The patient hand is placed on abdomen with hand wrist and elbow in straight line. Now patient has to press down on the abdomen negative test indicates wrist at 0° suggestive of normal subscapularis. Positive test indicates patient can press on the belly by flexing wrist at 90° and intermediate result when wrist flexed 30–60° suggestive of partial function of subscapularis. It has sensitivity of 25% and specificity of 97.3%.
The bear-hug test: This test is most sensitive (60%) and with specificity >90%, can be considered single most accurate test for subscapularis injuries [11]. In this test patient has to place his hand on the opposite shoulder with the elbow anterior to the body. The examiner then applies an external rotation force while the patient attempts to maintain the hand on the shoulder. Positive test indicates patient cannot maintain the hand against the shoulder as examiner applies external rotation force (Figure 5).
Bear hug test.
All these tests allow diagnosing a partial tear in 30% of cases. More than 50% of tendon thickness is torn when the Napoleon test is positive; more than 75% when the lift-off test is positive.
X-Rays will demonstrate any coracoid pathology, associated acromial spur degenerative changes (Figures 6 and 7).

Ultrasonography (USG) is less reliable than MRI in diagnosing the Subscapularis tears.
USG is more preferred to assess the tendon repaired after shoulder arthroscopy (Figure 8).
Ultrasonography of subscapularis tear.
MRI is the noninvasive procedure of choice to diagnose subscapularis rears. It provides higher diagnostic reliability. Arthro-MRI is even more perfect and accurate as compared to conventional MRI in patients with subscapularis tendon tears.
An indirect sign, often associated with partial subscapularis tears, is a medial dislocation of the long head of the biceps.
There are high chances of partial tears being missed on conventional MRI as compared to Contrast MRI. Fatty degeneration (fatty infiltration) is negative prognostic factor for full functional recovery of the shoulder. The percentage of fatty infiltration predictive of success after cuff repair is lower than 75%.
MR arthrography is accurate in the detection and grading of lesions in the subscapularis tendon. The specificity of findings on transverse images for this diagnosis can be improved by including ancillary signs and findings from parasagittal images (Figures 9–11).

In comparison with other rotator cuff tears, subscapularis tear is less common, it seems to have been underestimated. Because of recent attentions to subscapularis tendon, new types of such tendon’s lesions have been identified and described. The subscapularis tendon tears may be classified as partial and complete, retracted and not retracted, superior involving the upper third and inferior (extended to the lower third. Lafosse described a five-type classification of subscapularis tendon lesions according to anatomic data and arthroscopic lesion-related findings.
The classification system by Lafosse:
II Complete lesion superior one third
III Complete lesion superior two-thirds
IV Complete lesion with head centered and fatty degeneration<stage3
V Complete lesion with eccentric head and fatty degeneration>stage3
A type I tear is a simple erosion of the upper third of the tendon without any disconnection to the bone (Figure 12).
Type I tear.
In a type II is a frank detachment of the upper portion of the tendon (Figure 13).
Type II tear.
A type III lesion is characterized by involvement of all the insertion of the tendon without detachment of the lower third of the muscular portion (Figure 14).
Type III tear.
In type IV tears, the subscapularis tendon is completely detached from the lesser tuberosity and the humeral head is centered within the joint (Figure 15).
Type IV tear.
In a type V lesion, the lesion is complete, the humeral head is translated anteriorly and superiorly, with coracoid impingement and fatty degeneration of the muscle fibers of the subscapularis (Figures 16 and 17).
Type V tear.
Type V tear Intra-articular view.
There are multiple treatment options in the management of subscapularis tears, with non-operative care indicated in some. In older, inactive patients with smaller a traumatic tears a conservative treatment comprised of physical therapy, anti-inflammatories, and activity modification must be tried. Patients unresponsive to conservative treatment can be considered for surgical repair.
Open repair surgery is performed by deltopectoral approach or anterior deltoid splitting approach in beach chair position. The anterior deltoid splitting approach is mainly used in subscapularis tear associated with supraspinatus or infraspinatus. The deltopectoral approach is used in isolated subscapularis tear. In deltopectoral approach advantage is deltoid is still intact and we can visualize retracted subscapularis tendon. Careful blunt dissection should be done to protect axillary nerve as it lies inferior border of subscapularis. In both approaches we have to open rotator interval from bicipital groove to glenoid. We should be careful for any bicep tendon or supraspinatus pathologies. “Bare bone” will be present between the lesser tuberosity and articular humeral head when there will be complete tear of subscapularis. To visualize the superior subscapular tendon margin, the humeral head must be pushed posteriorly and the tendon seen inside the glenohumeral joint. Tendon should be isolated and then released from its insertion site. In the bare area on the lesser tuberosity with the help of suture anchors or intraosseous sutures the detached tendon is fixed. To fully mobilize the torn tendon if the tendon is too much retracted then release of glenohumeral ligament on the articular side becomes very important step. Once the surgery is complete, the surgeon must assess the range of motion of the shoulder as well as the stability of the repair (Figures 18 and 19).

Arthroscopic subscapularis repair surgery can be done with the patient in lateral or beach-chair position. Arthroscopy allows a complete visualization of intraarticular aspects of the joint. In proper position the subscapularis footprint can be visualized that is arm in abduction and internal rotation. For improved visualization of the footprint, a new technique described by Burkhart that is “Posterior lever push.” In this technique, the elbow is grasped while a posterior force is applied on the humerus. This results into better visualization of subscapularis insertion site as the intact fibers are pulled away from footprint. This technique may increase the field of view by 5–10 mm. Another method is use of a 70° scope for better visualization of the footprint. The assessment of the tear depends upon the size, direction of the tear and the amount of retraction. It becomes highly impossible to distinguish from conjoint tendon when the tendon is totally retracted. In this situation, finding of “the comma sign,” an arc-shaped area of tissue at the superior-most aspect of the subscapularis becomes important. Fibers from the superior glenohumeral ligament as well as the medial head of the coracohumeral ligament comprise the “comma” which serves as a useful lighthouse for the tendon edge.
Biceps tendon pathology like medial subluxation, tears and even SLAP lesions are common with Subscapularis tears, it should be evaluated. The biceps tenotomy or tenodesis is required in order to enhance visualization and protect the repair in case of these pathologies. After a tear of the subscapularis has been identified, subsequent repair should be performed before other shoulder areas are addressed.
Mainly three portals are made to repair the subscapularis.
The posterior portal (P) is the primary viewing portal as commonly used in glenohumeral arthroscopy.
An anterosuperolateral portal (AL) is used to prepare the subscapularis footprint as well as for repair. It lies just anterior to the biceps tendon and anterolateral edge of the acromion.
An anterior portal (AI), is made on just lateral to the coracoid process and it is used for anchor placement.
It becomes very difficult to treat retracted subscapularis tears due to inadequate immobilization. Lo and Burkhart describe the “interval slide in continuity” in which part of the rotator interval and coracohumeral ligament are resected and released in order to increase mobility of the subscapularis tendon. The coracohumeral ligament is “peeled away” from the lateral coracoid, which provides the subscapularis with greater excursion. Preservation of the coracohumeral ligament also allows stable tissue for any associated posterior tears to be approximated via margin convergence.
In this procedure foot print is made by using the same principles that are used for rotator cuff surgery. When the lesions are retracted the bone surface is carefully decorticated, the foot print and subchondral bone exposure is medialised up to 7 mm. Healing process and biological response at the bone tendon interface is improved by micro fractures [12].
Depending upon choices absorbable or non-absorbable anchor sutures can be used in same manner like rotator cuff repair surgery. In almost all cases single anchor suture can be sufficiently used. It is advised that biomechanically one anchor for each square cm. of bare foot print area. It is advised that double row repair has advantages like in rotator cuff surgery in terms of strength and least failure rates. You can use bridging sutures or knotless anchors alternatively. To pass the sutures we can use same techniques that we are using in rotator cuff surgery, paying attention that the sub-coracoid space is far narrower than the sub-acromial space. By using small instruments which pass within the tendon without damaging lesion further, double layer and splitting tears need to be noted. Diagnostic arthroscopy can be used in partial tears thus allowing to undertake transtendineous repair similarly to repair of “PASTA” lesions of the rotator cuff [13] (Figures 20–31).

Chlorophyll and carotenoid are important pigments that have been used as intrinsic optical molecular probes to observe plant performance during different phases of development. Chlorophyll and carotenoid are biosynthesized in chloroplast and their metabolism is closely related with the chloroplast development. Chlorophyll biosynthesis begins with the formation of 5-aminolevulinic acid (ALA) from glutamate (Glu) via Glu-tRNA synthetase, Glu-tRNA reductase (GluTR) and Glu-1-semialdehyde aminotransferase (GSA-AT) [1]. Eight molecules of ALA are condensed, eventually forming the symmetric metal-free porphyrin, protoporphyrin IX (Proto IX), which is a common precursor of haem and chlorophyll. The biosynthesis of chlorophyll continues by insertion of Mg2+ into Proto IX and followed by several steps in the chlorophyll cycle to create protochlorophyllide.
\nFurther, reaction is one of the most interesting steps because this is the first step in chlorophyll biosynthesis that requires light: the NADPH:protochlorophyllide oxidoreductase converts protochlorophyllide into chlorophyllide. This reaction is then continued to produce chlorophyll (chl) a and b. So, when dark-grown etiolated seedlings are exposed to light, protochlorophyllide is immediately converted to chlorophyllide and then further to synthesis of chl. Once chl a and b are formed and properly incorporated into the thylakoid membranes and associated photosystems, chloroplast is fully functional to do photosynthesis [2].
\nPlant carotenoids are synthesized and accumulated exclusively in plastids, most importantly, chloroplast and chromoplast [3]. There are two types of plant carotenoid: carotene, which is cyclized and uncyclized hydrocarbons, and xanthophylls, which are oxygenated derivatives of carotenes. Carotenoid synthesis is initiated by the formation of C40 compound phytoene by the head-to-head condensation of two molecules of geranylgeranyl diphosphate (GGDP) by phytoene synthase and then to a series of 4 sequential desaturation reactions, by two separate enzymes to produce lycopene, which has 11 conjugated double bonds [4]. Lycopene is then cyclized to α-carotene or β-carotene, which is then further hydroxylated to produce colorful xanthophylls such as lutein, β-cryptoxanthin, zeaxanthin, antheraxanthin, violaxanthin and neoxanthin. The biosynthesis and accumulation of carotenoids in the dark-grown etiolated seedling are essential for the assembly of membrane structure and benefits the development of chloroplast when seedlings emerge into the light [5]. Understanding the relationship between structure and photophysical properties of these pigments can provide insights into a better study of how photosynthesis works at the molecular level in chloroplast.
\nThe photophysical properties and functions of chlorophyll and carotenoid reside in their chemical structure. Chlorophylls are defined as cyclic tetrapyrroles carrying a characteristic isocyclic five-membered ring that are functional in light-harvesting or in charge separation in photosynthesis [6]. The chemical structure with IUPAC numbering scheme of chl a is shown in Figure 1. It is a squarish planar molecule, about 10 Å on a side. An Mg atom in the center of the planar portion is coordinated to four nitrogen atoms. The five rings in chlorophylls are lettered A through E, and the substituent positions on the macrocycle are numbered clockwise, beginning in ring A. Chlorophyll has two molecular axes: y-axis is defined as passing through the N atoms of rings A and C and x-axis passing through the N atoms of rings B and D. The delocalized π electron system extends over most of the molecule, except for ring D, in which the C-17—C-18 double bond is reduced to a single bond. The tail is formed by condensation of four isoprene units and is then esterified to ring D. It is often called phytol tail, after the polyisoprenoid alcohol precursor that is attached during biosynthesis. Because of the reduced ring D, plant chlorophylls such as chl a and b are classified as chlorins rather than porphyrins. These types of pigments have (in organic solvents) absorption bands around the blue and red spectral regions (Figure 2a), which are called B (or Soret) and Q bands, respectively, and arise from π→π* transition of the four frontier orbitals [7, 8]. One band each pair is polarized along the x-axis (Bx, Qx) and other along y-axis (By, Qy). The strong absorption band at the maximum absorption wavelength (λmax) 660 nm is called Qy transition band, which corresponds to the electronic transition polarized along the y-axis. The Qx-band of chl a shows a weak band near 550 nm, while the two overlapping Soret (B) bands show at about 430 nm. The chemical structure of Chl b is identical to chl a except at the C-7 position, where a formyl group replaces the methyl group. This structural change results in a shift of the Qy maximum absorption to shorter wavelength. The fluorescence spectrum of chlorophylls peaks at slightly longer wavelengths than the absorption maximum. The fluorescence emission (Figure 2b) is polarized along the y molecular axis, as it is emitted from the Qy transition. Shift of the emission to the longer wavelength side of the main transition is known as Stokes shift. In light reaction, chlorophyll plays as key pigment in the collection of light energy in the light-harvesting complexes and to carry out reversible photochemical redox reaction (Krasnovsky reaction) in the reaction centers.

Structure of carotenoid is characterized by a linear chain of conjugated π-electron double bonds (Figure 1). In oxygenic organisms, carotenoid usually contains ring structures at each end, and most carotenoids contain oxygen atoms, usually as part of hydroxyl or epoxide groups. The primary molecular factor that gives rise to their strong absorption bands in the visible spectral region is the number of π-electron conjugated double bonds, N. The position of the absorption maxima is affected by the length of the chromophore, the position of the end double bond in the chain or ring and the taking out of conjugation of one double bond in the ring or eliminating it through epoxidation. Progressive movement to longer wavelengths (bathochromic shift) is illustrated by the absorption spectra of the acyclic carotenoid of increasing chromophore length. Carotenoids show different optical characteristics in various solvents, depending on the polarizability of the solvent [9, 10]; however, generally they have a typical three-peaked absorption spectrum with well-defined maxima and minima (fine structure) (Figure 2a). A ring closure as in β-carotene produces a less-defined fine structure. The introduction of a carbonyl group in conjugation with the polyene system produces a bathochromic shift and the loss of fine structure [4]. The influence of other substituents such as OH is negligible, for example, β-carotene, cryptoxanthin and zeaxanthin all have very identical absorption spectrums. Owing to the double bonds in the molecule, all carotenoids exhibit cis-trans isomerization (stereomutation). A cis double bond implies a configuration with the highest-priority group on the same side, whereas in the trans configuration they are on opposite sides. The absorption spectrum of a cis isomer presents a subsidiary peak in the near-ultraviolet, the cis peak; generally, it is located 143 nm from the longest wavelength maximum. For example, cis peak will appear at 330 nm if the longest wavelength maximum is 473 nm. In photosynthetic systems, carotenoid has essential functions. First, carotenoid is an accessory pigment in the collection of light energy in the spectral region which chl does not absorb and in transferring energy to a chl pigment [11, 12]. Second, carotenoid functions in a process called photoprotection by quenching triplet state of chl before it reacts with oxygen to form singlet oxygen species (ROS) [13, 14]. Third, carotenoid regulates energy transfer in the light-harvesting antenna through a process called xanthophyll cycle, to avoid over-excitation of the photosynthetic system by safely dissipating excess energy [15, 16].
\nIn the chloroplast interior, there are four main constituents in plant thylakoids, that is, photosystem II (PSII), cytochrome b6f, photosystem I (PSI) and the ATP synthesis. Chlorophylls and carotenoids are embedded in PS II and PSI, large pigment-protein clusters, the structures of which are perfectly adopted to ensure that almost every absorbed photon can be utilized to drive photochemistry. Both PSII and PSI consist of two moieties, that is, core complex or the reaction center that is responsible for charge separation and light-harvesting antenna complexes that surround the core complex and have functions to increase the capture of light energy and energy transfer to the reaction center in the core complex.
\nOne can detect chlorophyll and carotenoid bound in PSII and PSI in chloroplast by measuring their absorption and fluorescence spectra. Figure 3a (solid red line) shows the absorption spectrum of diluted chloroplast that is indicated by red shift of Chl a, Chl b and carotenoid’s bands because these molecules are bound as pigment-protein complexes in chloroplast. The Soret band of chl a in the complexes was detected at 438 nm while in the MeOH it was found at 432 nm (Figure 2a black line). The fluorescence emission spectra (Figure 3b) indicate a strong emission band of PSII complexes with maximum wavelength at (λmax) about 682 nm and weak emission band of PSI complexes with λmax at about 730 nm. It is shown here that Chl a acts as the main contributor to the excitation band at 434 nm and it shows that excitation at 434 nm (Soret band) produces stronger emission intensity, while the excitation at 475 and 512 nm, correspond to Chl b Soret band and carotenoid, respectively, produces weaker emission intensity. If we monitor the emission at 682 nm and measure the excitation spectrum, it shows that the PSII emission at 682 nm is the result of contribution from Chl a, Chl b and carotenoids (Figure 3a solid black lines) with bands at λmax about 414, 434, 475 nm, respectively.
\n(a) Overlaid of UV–Vis absorption (red) and fluorescence excitation (black) (λem = 682 nm) spectra of chloroplast and (b) emission spectra of chloroplast with excitation at 434 (black), 475 (red) and 512 (blue) nm. Measurements were conducted at ambient temperature. The isolation of chloroplast was carried out as follows: 20 g of suji leaves (Pleomele angustifolia) were washed with running water and cut. The leaves were then homogenized in 200 mL ice-cold isolation buffer (300 mM sorbitol, 50 mM HEPES-KOH pH 7.5, 2 mM EDTA, 80% acetone, 0.1% BSA) for 10 min in a cold environment, followed by filtration using cloth. Centrifugation was conducted in 2 steps, to discard cell debris at 200 g, 4°C, 20 min and to harvest chloroplast pellet at 3000 g, 4°C, 20 min. Final chloroplast pellet was collected and subjected to spectrum UV–VIS (Shimadzu UV-1700)and fluorescence measurement (Jasco FP-8500).
The current high-resolution structural models of antenna complexes have been obtained only for LHCII (2.72 Å) and recently for CP29 (2.8 Å) from PSII of spinach [17, 18]. Here we focus more on the LHCII structure. LHCII shows trimeric structure. Each monomeric contains three transmembrane α-helices, a, b and c (Figure 4a). One monomeric subunit contains eight chlorophyll (Chl) a pigments, six Chl b, two luteins (Lut), neoxanthin and one additional xanthophyll [17, 19]. The 14 chlorophylls are non-covalently attached in the protein cavity. Four carotenoid binding sites per monomer have also been characterized, but in this case the type of carotenoid bound can vary. Typically, two lutein molecules are in groves on both sides of helices a and b and have been likened to a cross-brace. A third carotenoid, 9-cis neoxanthin, is located in the Chl b-rich region near helix c. The fourth carotenoid is located at monomer-monomer interfaces in the trimer. It has been suggested that this site accommodates carotenoids that can participate in the xanthophyll cycle. It depends on the external stress level of the plant; the fourth carotenoid is either violaxanthin (no or low stress) or zeaxanthin (high stress) [20]. In this structure, the carotenoids are in van der Waals contact with the chlorophylls [9]. This is essential as carotenoids in LHCII act as accessory light-harvesting pigments and photoprotectors. The accessory light-harvesting function represents singlet-singlet energy transfer from the carotenoid to the chlorophylls. Since the singlet excited state lifetime of the carotenoid is quite short, approximately 200 fs, the carotenoid must be in close distance to a chlorophyll molecule if the energy transfer is to be efficient. Photoprotection function represents the quenching of triplet excited state of chlorophylls and so preventing the formation of singlet oxygen. This triplet-triplet exchange reaction also requires the carotenoid to be in close contact with the chlorophylls. Regarding CP29, it binds 3 carotenoids and 13 chlorophyll molecules [18]. The position of some chlorophyll binding sites in CP29 differs from LHCII.

(b) Side-view of LHCII structure shows chlorophyll and carotenoid molecules are packed densely and close to each other (within van der Waals contact), enabling the crucial photo-protective role of these molecules to function by quenching triplet chlorophyll excited states.

(d) Structure of PSI from Synechococcus elongatus [29]; overview of the complete trimer looking along the membrane normal from the stromal side with each polypeptide of the trimer colored differently and chlorophyll molecules given in green. The two main proteins that comprise a monomer are PsaA (yellow) and PsaB (magenta). The electron transport chains are in the center of each monomer. (f) PSI core reaction center component co-factors of the electron transport chain are viewed along the membrane plane. The two branches are related by the pseudo-twofold symmetry axis. The representative pair of chlorophyll molecules on the branches are labeled A or B indicating whether the Mg2+ is coordinated by PsaA or PsaB. The iron–sulfur center of Fx involves residues from both PsaA and PsaB, while FA and FB are located in an extrinsic subunit called PsaC.
The current high-resolution crystal structure of PS II and PSI core complexes is limited to that from cyanobacteria and from pea, respectively [21, 22]. The core of PSII is a multi-subunit complex. Most of the chromophores involve light harvesting as well as electron transfer reaction and are bound to four main subunits, that is, D1, D2, CP43 and CP47. When the core of PSII and PSI reaction center structures is compared, the arrangement of the pigments and other electron transfer co-factors is also very similar (Figure 4c and d). Here, first we look at the PSII core reaction center. The core of reaction center of PSII is made from two major polypeptides called D1 and D2; each contains five membrane-spanning α-helices. These two helices clasp each other like two cupped hands holding on to each other. The redox cofactors are arranged into two arms that lie on either side of the point where the two groups of helices interact. This arrangement of the helices and the cofactors introduces a pseudo two-fold symmetry axes that runs through the center of reaction center normal to the plane of the membrane. In Figure 4e, it is seen that the electron transport pathway in PSII begins with a pair of chlorophyll molecules called P680 (PD1 and PD2). Then each arm contains, in order, one monomeric chlorophyll molecule, one pheophytin (a chlorophyll derivative) and one plastoquinone molecule. Here, only the D1 arm is active in electron transport. Upon excitation P680 becomes oxidized and one electron is injected out and passes down the active branch to the quinone QA. P680 is re-reduced by electron transfer from a special tyrosine residue called Z (Tyrz). A second turnover of P680 delivers a second electron to the plastoquinone and the secondary quinone QB is now reduced to QBH2. The hole on Tyrz is filled by electron transfer from the manganese cluster, the oxygen evolving complex. Every four turnovers of P680 stores four positive charges in the manganese cluster that are then used to oxidize water and evolve oxygen. While in CP43 and CP47, there are a total of 49 Chl a molecules that are bound and that function as internal antenna and allow excitation energy transfer from the peripheral antenna system to the reaction center.
\nUnlike PSII, in PS I, the same single polypeptides contain both antenna complexes (Lhca) and the reaction center core. The 3.3 Å resolution crystal structure of PSI from pea showed that plant PSI binds at least 173 Chl a and b molecules [22]. At this resolution of the crystal structure, it is not possible to identify the Chl species, but biochemical analysis of purified PSI indicated that it has a Chl a/b ratio in a range of 8.2–9.7 [23, 24]. A large number of Chl a and b molecules are bound to the Lhca protein, only about 100 Chl a are bound in the core complex, and the rest of Chl a and b are between these moieties. The latter represent the so-called “linker” chlorophylls which are located between Lhca monomers and “gap” chlorophylls (between Lhca and PSI core). The linker chlorophyll molecules probably play an important role in excitation energy transfer between Lhca antennas and from Lhca to the PSI core [20, 25, 26]. Based on biochemical analysis, PSI was reported to bind approximately 33/34 carotenoids, that is, about 12 carotenoid molecules are bound to Lhca, at the interface between Lhca and the core complex, and about 22 β-carotene are bound to the core [20, 23, 26]. Based on these biochemical analysis, it can be estimated that PSI-LHCII supercomplex contains about 215 chlorophyll and 45/46 carotenoid molecules.
\nThe core complex of PSI is composed of smaller number of subunits (15 subunit) than PSII. The large PsaA and PsaB subunit, which contain 11 trans-membrane helices each, forms a hetero-dimer that binds ~80 Chl a and ~20 β-carotene as cofactors for light harvesting as well as 6 Chl a, 2 phylloquinones and a 4Fe-4S cluster as cofactors for electron transfer reaction, with the exception of terminal electron acceptors (Fe-S clusters FA and FB) which are bound to the PsaC subunit [25]. At closer look (Figure 4f), the redox co-factors in the core reaction center are arranged into two arms that are located on either side of the region where two groups of helices interact with each other. Two chlorophylls form P700 and then each arm contains two monomeric chlorophyll molecules (the second one being in the equivalent position to the pheophytin present in photosystem II) followed by one quinone molecule. When P700 is oxidized, both arms of the electron transport pathway are able to work as it was reported that the electron can pass either down the B-branch or the A-branch [27].
\nChlorophyll and carotenoid can be isolated as free pigments, detached from the pigment-protein complexes, by organic solvent extraction. Important aspects such as the choice of organic solvents, light exposure and working temperature should be considered while isolating pigments. Based on the structure, chlorophyll is characterized with polar macrocycle ring with non-polar hydrocarbon tail. The structural difference between Chl b and Chl a is by having an aldehyde group in place of the methyl group at the macrocycle side group. This change is effecting the polarity of Chl b to be more polar in comparison to Chl a. In the case of carotenoid, structural difference can be seen from the number of conjugated double bonds and the presence of oxygen atoms. Considering these characteristics, mixtures of miscible polar and semi/non-polar solvents are used commonly to extract plant pigments. The mixture of solvent has double functions, that is, penetrating tissues/matrixes and extracting pigments from their lipophilic surrounding. During extraction, exposure of light should be avoided to reduce photodamage of the pigments. Temperature is also important. It is recommended to conduct extraction at lower temperatures, for example, on ice or using liquid nitrogen, to minimize activity of enzyme (e.g. chlorophyllase) that will catalyze breakdown. Antioxidant agent can be also added during extraction to avoid any unwanted oxidation.
\nAfter successful isolation, liquid chromatography has been widely used as an effective technique to separate individual type of pigments and for further purification. In this technique, the pigment separation is based on the polarity which depends on the interaction of pigment with the stationary and mobile phases. Elution method either normal phase or reversed phase is chosen according to the type of pigment to be separated. In addition, the choice of liquid chromatographic methods, namely thin layer chromatography (TLC), column chromatography (CC) and high-pressure liquid chromatography (HPLC), is referred to the speed, resolution and quantity of sample [30]. Currently, ultra-fast liquid chromatography (UFLC), a recent development of HPLC, has been used as a standard for liquid chromatography to achieve high-resolution data with low time consumption [31]. Purification with non-chromatographic method has also been developed, that is, purification method using dioxane has been effective to separate chlorophyll from most of the carotenoids and some lipids [32].
\nVarious types of column absorbents used for chromatographic separation of plant pigments have been well reviewed [30]. Here, we used a silica C30 column attached to UFLC analytic to achieve well separation of carotenoids from Pleomele angustifolia leaf using elution gradient program with mixture of water, methanol and methyl tert-butyl ether to separate, at least, 7 dominant pigments within 25 min. (Figure 5). The detailed identification of pigments, based on the chromatographic, spectrophotometric and mass properties, is summarized in Table 1. Chlorophyll a and chlorophyll b, α- and β-carotenes and violaxanthin are found to be the main chlorophylls and carotenoids, respectively, while the presence of lutein and zeaxanthin in this chloroplast is in low amount.
\nUFLC chromatogram of pigment extract from chloroplast of Pleomele angustifolia detected at 430 nm. The UFLC separation condition was as follows: Pigment separation was performed using UFLC equipped with PDA (Shimadzu) on C30 column (150 × 4.6 mm I.D; YMC) with a gradient elution program of water, methanol and methyl tert-butyl ether (MTBE) at the flow rate of 1 mL/min at 30°C.

Chromatographic, spectrophotometric and mass properties of pigments separated from the chloroplast of Pleomele angustifolia.
Larger-scale separation of Chl a and b can be achieved by CC using Sepharose CL-6B as the stationary phase and a mixture of 2-propanol (IPA) and hexane as the mobile phase. Chl a could be eluted using 1.5% IPA in hexane and Chl b with 10% IPA in hexane [33]. To achieve a pure, free carotenoid, saponification step is sometimes necessary to eliminate contamination of lipids and chlorophylls. Moreover, carotenoid ester can be hydrolyzed to produce parent carotenoid by using this method [34]. CC is usually used for carotenoid isolation in high quantity of pigment extract. Generally, the purpose of CC is to separate mixtures into carotenoid fractions which are either having high purity to be processed to crystallization or low purity to be extensively separated with further chromatography, that is, HPLC [35].
\nSilica and alumina are frequently used as the absorbent in the CC with the normal phase elution to separate the distinct carotenoids; however, it is not easy to use this method to separate carotenoid isomers, that is, geometrical isomers, diastereoisomers, and so on. In this case HPLC/UFLC can be used to overcome the difficulty in the separation of carotenoids by CC. Turcsi et al. (2016) revealed that the polar carotenoids including optical isomers, and region and geometrical isomers as well as non-polar carotenes, could be well separated by HPLC on C18 and C30 columns, respectively [36]. High purity of isolated pigment can be achieved by HPLC and crystallization processes. UFLC analysis of the purified zeaxanthin shows that this carotenoid had a high purity of around 99.3% (Figure 2, left). All purified pigments have purity higher than 95% (Figure 6).
\nPurification of zeaxanthin: (a) chromatogram detected at 450 nm. Insert figure is UV–Vis spectrum measured by UFLC diode array detector in the eluent and (b) ESI-MS/MS spectrum identification. The conditions of UFLC and ESI-MS/MS analysis were as follows: UFLC analysis of the purified zeaxanthin was performed using UFLC equipped with PDA (Shimadzu) on C30 column (150 × 4.6 mm I.D; YMC) with a gradient elution program of water, methanol and MTBE at the flow rate of 1 mL/min at 30°C. The purified zeaxanthin was directly analyzed to LCMS 8030 (Shimadzu) with an isocratic elution of 0.1% formic acid (FA) in water (10%) and 0.1% FA in methanol (90%) at the flow rate of 0.3 mL/min. MS analysis was operated under the following conditions: (1) heat block temperature = 400°C; (2) desolvation line temperature = 250°C; (3) nebulizing N2 gas flow = 3 L/min; (4) drying N2 gas flow = 15 L/min; (5) interface voltage = 4.5 kV; (6) interface current = 0.1 μA; (7) mass range 400–700 m/z; (8) ionization mode = positive and negative.
Chromatographic, spectrophotometric and mass properties of pigment are minimum requirements for pigment identification [35]. These properties for all purified pigments are shown in the Table 1. In Figure 7 (right), absorption spectra of the purified chlorophyll a and the purified β-carotene in acetone have the same maximum absorption wavelength (λmax) and other spectral properties, such as the fine structure and spectrum shape, compared to these pigments in the references [37, 38]. Absorption spectrum of chlorophyll a in acetone shows typical Soret (431 nm), Qx (617 nm) and Qy (662 nm) bands, while two well-defined peaks in the absorption spectrum of β-carotene are found at 454 and 482 nm. This pigment analysis based on the results of spectrophotometer UV–Vis could support the advance pigment analysis using HPLC/UFLC equipped with photodiode array detection and coupled with the mass spectrometry. The LCMS technique has provided a power tool for pigment identification [39, 40]. Tentative identification for zeaxanthin peak separated by HPLC/UFLC analysis with PDA revealed that zeaxanthin has similar retention time (tR), maximum absorption wavelength (λmax) and the shape of absorption spectrum (data not shown) compared to the isolated zeaxanthin from corn which is a well-known source of zeaxanthin [41]. In addition the mass analysis provides the precursor and fragment ions at the specific m/z and characteristic fragmentation pattern for pigment identification. Mass spectrum of Chl a indicated the molecular ion [M]+ detected at m/z 893.6 and a fragment ion [M-Mg]+ at m/z 871.6 related to the loss of magnesium as the central metal of chlorophyll (Figure 1). This mass spectrum of Chl a agrees with the result that was reported [42].
\nPurification of Chl: (a) chromatogram detected at 660 nm. Insert figure is UV–Vis spectrum measured by UFLC diode array detector in the eluent and (b) ESI-MS/MS spectrum. The condition of UFLC and ESI-MS/MS analysis was as follows: UFLC analysis of the purified chlorophyll a was performed using HPLC equipped with PDA (Shimadzu) on C30 column (150 × 4.6 mm I.D; YMC) with a gradient elution program of water, methanol and MTBE at the flow rate of 1 mL/min at 30°C. The purified chlorophyll a was directly analyzed to LCMS 8030 (Shimadzu) with an isocratic elution of 0.1% formic acid (FA) in water (10%) and 0.1% FA in methanol (90%) at the flow rate of 0.3 mL/min. MS analysis was operated under the following conditions: (1) heat block temperature = 400°C; (2) desolvation line temperature = 250°C; (3) nebulizing N2 gas flow = 3 L/min; (4) drying N2 gas flow = 15 L/min; (5) interface voltage = 4.5 kV; (6) interface current = 0.1 μA; (7) mass range 400–1000 m/z; (8) ionization mode = positive and negative.
Chlorophyll and carotenoid are chloroplast pigments which are bound non-covalently to protein as pigment-protein complex and play a vital role in photosynthesis. Their functions include light harvesting, energy transfer, photochemical redox reaction, as well as photoprotection. The exact number and stoichiometry of these pigments in higher plants are varied, but their compositions include Chl a, Chl b, lutein, neoxanthin, violaxanthin, zeaxanthin and β-carotene. Liquid chromatography methods are well developed to separate and purify different types of pigments. Identification and characterization of pigments can be well observed by spectroscopy methods such as UV–Vis absorption, fluorescence and mass spectrometry.
