Plants being sessile suffer from several abiotic stresses during growth. These include drought, salinity, heavy metal, temperature, and nutrient stress. Salt stress is one of the devastating abiotic stresses that plant suffers under natural growth conditions. It is more common in arid regions due to excessive evaporation, which causes the accumulation of inorganic salts disrupting the plant metabolism. It also triggers the influence of drought stress, as plants are unable to absorb water. Additionally, it also causes oxidative stress in plant tissues. Thereby, plant adaptation to salt stress, rely on signals and pathways that help plant in establishing cellular ionic and osmotic homeostasis. Stress-responsive transcription factors play crucial roles in the regulation of gene expression in responses to salt stress. Moreover, genome editing has gained much attention for the engineering of traits for the better adaptation of plants to salt stress. This chapter elucidated the plant\'s physio-biochemical responses and molecular mechanisms to salt stress.

Potato (Solanum tuberosum L.) is one of the essential non-cereal crops with noticeably greater production and consumption rates across the world. Because of the diverse range of utilization of nutritious tubers, potatoes can be used as an alternative food to address regional, national, and global food security issues compromised by global climate change. Since potato yield and quality are dramatically affected by abiotic stress conditions, the development of potato plants showing greater performance after being exposed to individual or combined stress treatments has become intriguing for the past decade. In this book chapter, recent studies and/or approaches associated with potato genomics, transcriptomics, and identification of miRNAs are summarized to discuss the response of potatoes to abiotic stress factors in different regulatory levels. Such a summary should encompass the importance and identification of factors for the development of potato plants under current and potential exacerbating effects caused by abiotic stress.
