The use of plant growth promoting bacteria may prove useful in developing strategies to facilitate plant growth under normal as well as
diverse abiotic stress conditions. The application of microbes with the aim of improving nutrients availability for plants is an important practice
and necessary for sustainable agriculture. During the past couple of decades, the use of microbial inoculants for sustainable agriculture has
increased tremendously in various parts of the world. Significant increases in growth and yield of agronomically important crops in response
to inoculation with plant growth promoting (PGP) microbes have been repeatedly reported. The actual biodiversity of PGP microbes belong to
different groups including Actinobacteria, Bacteroidetes, Balneolaeota Firmicutes, Proteobacteria and Spirochaetes. PGP bacteria are naturally
occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion either directly by solubilization
of phosphorus, potassium and zinc; production of indole acetic acids, gibberellic acid, cytokinin; biological nitrogen fixation or in-directly by
production of ammonia, hydrogen cyanide, siderophore and biocontrol against different plant pathogens. In this review, we have discussed
method of isolation, characterization, identification and biodiversity of bacteria associated with crops and further mechanisms of plant growth
promotion under the normal as well as diverse abiotic stress conditions.
