Global food security can be achieved through rigorous agricultural security because agriculture is the basis of food. Several reports have shown that environmental stresses greatly affect agriculture productivity around the globe. Abiotic stressors cause the stimulation of ethylene biosynthesis in plants, which is a crucial mediator of environmental stresses in plants. Thus, the mitigation of abiotic stress in plants is pivotal for enhancing plant growth and crop productivity. Many rhizospheric and endophytic bacteria encoding for 1-aminocyclopropane-1-carboxylate (ACC) deaminase have been used to modulate ethylene production inside plant tissues and alleviate the harmful effects of the stressful conditions. Various researchers have reported ethylene biosynthesis and its alleviation through ACC deaminase-producing bacteria. Despite this, the function and control of endogenous abscisic acid (ABA) in ethylene biosynthesis must be deciphered under normal and stressful conditions. The robust expression of the bacterial acdS gene in transgenic plants is another pragmatic approach for alleviating abiotic stressors on different plants. The role of ACC deaminase-producing bacteria and transgenic plants expressing the acdS gene in combating stress ethylene is comparable, but transgenic plants can express the acdS gene under extreme environmental conditions while bacteria can not maintain its association with plants in such harsh conditions. The present review summarizes the recent work on ACC deaminase-producing rhizospheric and endophytic bacteria, their mechanism of action at the cellular level, physiological function, mitigation of abiotic stress conditions, and the potential use of bacterial acdS gene in horticultural crops over the last 10 years.
