摘      要：Drought stress affects plant growth and causes significant issues in meeting global demand for food crops and fodder.Drought can cause physiological,physicochemical,and morphological changes in plants,which negatively affects plant growth and productivity.To combat this under the increasing global threat of water shortage and rapid population expansion,it is crucial to develop strategies to meet global food demands.Plant growth-promoting rhizobacteria(PGPR)may provide a safe solution to enhancing crop yields through various mechanisms.These soil bacteria can provide drought tolerance to crop plants,allowing them to survive and thrive in water-scarce conditions.Productions of phytohormones,free radical-scavenging enzymes,and stress-combating enzymes that can increase tolerance to drought-induced stress are key features of plant-associated microbial communities.This review summarizes the beneficial properties of microbes that help plants tolerate water scarcity and highlights the bacterial mechanisms that enhance drought tolerance in plants.
