Drought stress is one of the most important abiotic stresses on plants,which not only affects the growth and reproduction of plants seriously,resulting in reduced crop yield,but also damages the ecological environment.At pres-ent,besides improving the growth environment of plants artificially by constructing irrigation projects,plant growth promo-ting microorganisms(PGPM)are also used as plant growth regulators to maintain normal physiological and biochemical re-actions of plants and alleviate the adverse responses caused by drought stress.This paper aimed at studying how plant growth promoting microorganisms promoted plant growth under drought stress,and summarized relevant contents by consult-ing literature,aiming to clarify the positive regulation of plant growth promoting microorganisms on plant growth under drought stress.
