|a Role of plant nsLTP in biotic stress is well reported; however, their role during abiotic stress is far from clear. This study comprises genome-wide identification of LTPs and characterizes the regulation and function of two Triticum aestivum lipid transfer proteins, TaLTP40 and TaLTP75, under stresses that influence membrane fluidity. A total of 105 LTP gene family members have been identified. The selected LTPs for functional validation were highly expressed during salt, cold and drought stress. Further, selected LTPs showed differential expression thermotolerant and thermosusceptible wheat cultivars. Higher expression of many TaLTPs was observed under different abiotic stresses in thermotolerant wheat cultivars as compared to thermosusceptible cultivars. TaLTPs regulation was correlated with light energy distribution studies under similar stress conditions. Cellular localization revealed localization of different TaLTPs to the tonoplast membrane along with the organelles involved in the secretory pathway. Induction of TaLTPs was observed upon treatment with dimethylsulphoxide. TaLTP40 and TaLTP75 overexpressing transgenic Arabidopsis showed a constitutively enhanced salt tolerance. Both the TaLTP40 and TaLTP75 overexpressing lines performed better in terms of chlorophyll a fluorescence, total chlorophyll content, membrane injury index, total biomass, percentage germination, percentage survival and relative growth rate. Hence, our analyses indicate that TaLTPs expression might be driven by change in membrane fluidity and could be involved in transferring membrane lipids to the biological membranes thus imparting tolerance to various abiotic stresses
