Abstract: Soil salinity inhibits the growth of plants and has become one of the major factors that limit agricultural productivity. Plant-growth-promoting rhizobacteria (PGPR) colonizing the rhizosphere of many plants stimulated plant growth under salt stress condition, meanwhile, PGPR can induce plant salt tolerance. This paper reviewed PGPR species that could confer plants induced salt tolerance and the potential mechanisms of PGPR improving plant salt tolerance was reviewed from two aspects including PGPR metabolite and physiological changes in plants driven by PGPR under salt stress condition. Understanding the mechanisms responsible for induced salt tolerance conferred by PGPR, will provide theoretical basis for the large-scale application of rhizobacteria in saline environments.

Key words: plant-growth-promoting rhizobacteria (PGPR), plant, salt stress, induced salt tolerance
