Drought stress is a severe environmental constraint among the emerging problems. Plants are highly vulnerable to drought stress and a severe decrease in yield was recorded in the last few decades. So, it is highly desirable to understand the mechanism of drought tolerance in plants and consequently enhance the tolerance against drought stress. Phytohormones are known to play vital roles in regulating various phenomenons in plants to acclimatize to varying drought environment. Abscisic acid (ABA…

TLDR
The application of PGPM/AMF represents a promising approach to increase nutrient availability and expedite the development of sustainable agriculture.
Plant Responses to Exogenous Salicylic and Jasmonic Acids Under Drought Stress
TLDR
The SA and JA mechanisms of actions in changing physiological and biochemical properties of plants favoring drought tolerance were discussed and the critical roles of these growth regulators in enhancing photosynthesis activities under drought stress have been confirmed.
Phytohormone signaling and crosstalk in regulating drought stress response in plants.
TLDR
This review is focused on the pivotal role of phytohormones in water deficit responses, including their manipulation for mitigating the effect of the stressor, and the inherent complexity of existing crosstalk accrued among them during the progression of drought stress, which instigates the tolerance response.
