摘      要：Abiotic stresses are a significant factor that considerably limits plant growth and productivity.Methylotrophs are an essential group of bacteria that utilize volatile carbon compounds,are prolific colonizers of different plant parts,and play a vital role in plant growth promotion(PGP)under stress conditions.Numerous rhizospheric and phyllosphere methylotrophs have been reported to exhibit PGP activities with superior stress-tolerating capacity against drought,heavy metal,salinity,high and low temperatures,solar ultraviolet radiation,and other harsh environmental conditions.Methylotrophs promote plant growth through N2 fixation,phosphate solubilization,production of phytohormones(i.e.,auxins,gibberellins,and cytokinins),1-aminocyclopropane-1-carboxylic acid(ACC)deaminase activity,siderophore,ammonia production,and secondary metabolites.The production of these compounds by methylotrophs protects a plant against adverse environmental conditions and influences its productivity.This review discusses the role methylotrophs play in managing various abiotic stresses,how they help mitigate these stresses,and how they improve agricultural productivity.
