“…However, these regions are subjected to severe water-deficient conditions and seasonal drought, particularly from early May to the mid-May, the area covered by drought has been above 30% of the nation’s crop (Yang et al, 2018; Zhang et al, 2018; Figure 1A). According to the statistics of the Ministry of Water Resources of the People’s Republic of China (2018), the annual loss of industrial crops caused by drought in China accounts to 28.22 billion yuan, and peanuts account for about 20% (Li et al, 2014; Aninbon et al, 2016; Qin et al, 2017). Planting spring cultivars earlier is a feasible measure to circumvent spring sowing drought in peanut production, as well as in prolonging the vegetative growth period and increase nutrient accumulation for crop propagation (Rana et al, 2017).…”

Early sowing has been extensively used in high-latitude areas to avoid drought stress during sowing; however, cold damage has become the key limiting factor of early sowing. To relieve cold stress, plants develop a series of physiological and biochemical changes and sophisticated molecular regulatory mechanisms. The biomembrane is the barrier that protects cells from injury as well as the primary place for sensing cold signals. Chilling tolerance is closely related to the composition, structure, and metabolic process of membrane lipids. This review focuses on membrane lipid metabolism and its molecular mechanism, as well as lipid signal transduction in peanut ( Arachis hypogaea L. ) under cold stress to build a foundation for explicating lipid metabolism regulation patterns and physiological and molecular response mechanisms during cold stress and to promote the genetic improvement of peanut cold tolerance.

“…P. sepium Bunge evidently eliminates drought stress-induced peroxide stress primarily by increasing POD activity 31,33 . Studies have indicated that there is a significant increase in SOD, POD, and catalase activities 34 and peanut seedlings 35 under various drought conditions. This finding suggests that, under drought stress, changes in the activities of plant protective enzymes are closely related to the habitat and drought resistance of the plants.…”

Bin cao 2 this study investigated the physiological and ecological changes in P. sepium Bunge and elucidated the physiological regulatory mechanisms underlying the adaptation of P. sepium to drought stress in shell sand. Drought stress led to a significant decrease in the net photosynthesis rate (P n) and respiration rate of leaves and a decrease in low-intensity light-use efficiency (LUE) and light ecological amplitude. An increase in drought stress led to a considerable decrease in the photosynthetic electron transport rate in the P. sepium leaves and a significant increase in the amount of light energy dissipated as heat. In addition, the photosynthesis process suffered from severe photoinhibition. P. sepium plants counteracted the effects of drought stress primarily by increasing their peroxidase (POD) activity and by regulating membrane lipid peroxidation by secreting greater numbers of osmotic adjustment substances (proline (Pro) and soluble sugars (Ss)) and malondialdehyde (MDA). As drought stress increased, both the stem sap flow rate and the cumulative sap flow of P. sepium decreased considerably. P. sepium Bunge adapts to drought stress through interregulatory activity between photosynthesis, water-related physiological activities, and physiological and biochemical processes, and this species exhibits relatively high adaptive plasticity to drought.
