Plants are exposed to various biotic and abiotic stresses, thereby growth become arrested due to accumulation of stress ethylene. Drought conditions may additionally persist for numerous months to years and can appreciably have an effect on plant health and survival. In this regard, various technologies including traditional breeding and genetic engineering are used to cope with drought stress. Some plant growth-promoting rhizobacteria (PGPRs) have the capacity to stimulate plant growth even under stressed conditions by reducing ethylene levels in plants. PGPR contain the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase that assists plant growth and development by minimization of plant ethylene levels. ACC deaminase has the capacity to metabolize the ACC into a-ketobutyrate and ammonia and thereby checks the production of ethylene. Indirectly, endophytic bacteria also improve osmotic adjustment, relative water content, and antioxidant activity of inoculated plants. Altogether, these bacterial-mediated drought tolerance and plant growth–promotion continue even under drought conditions which lead to promote plant growth promotion and its yield. In this review we are trying to insight a brief outline of bacterial ACC deaminase and their role in alleviation of water stress tolerance in plants.
