Trehalose induced drought tolerance in plants: physiological and molecular responses

Drought stress is significant abiotic that limits crop growth and productivity across the globe. The intensity of drought continuously rises due to rapid climate change. Drought-induced alterations in physiological bio-chemical processes by generating membrane dis-stability, oxidative stress, nutritional imbalance leading substantial reduction productivity. Plants accumulate various osmolytes protect themselves from stresses' harmful effects. Trehalose (Tre) a non-reducing sugar found multiple microbes ranging bacteria yeast plants it possesses an excellent ability improve tolerance. appreciably enhanced plant growth, counter induced damages maintaining cellular membranes, water relations, stomatal regulation, photosynthetic activities, nutrient uptake, osmolyte accumulation, activating proteins detoxifying reactive oxygen species (ROS) strengthening anti-oxidant system. Therefore, essential understand mechanism exogenous endogenous Tre mitigating drought-induced identify potential research questions must be answered future. better appraise benefits tolerance this review, we discussed diverse molecular mechanisms regulated under stress. We have complete updated picture on topic orientate future directions topic.
