Abstract:

Plant growth promoting rhizobacteria (PGPR) is a type of beneficial bacteria that can effectively alleviate the damage of salinity to plant, promote the absorption of mineral nutrients by plants and have a significantly antagonistic effect on pathogenic bacteria. Rational application of PGPR has extremely important application potential in stress resistance mechanism of plant, soil ecological remediation and breeding strategy improvement. In this review, we summarize the research progress of PGPR in promoting plant nutrient absorption, regulating plant hormone homeostasis and alleviating the damage of salinity to plant, and provide a theoretical basis for analyzing the application prospect of PGPR in future breeding improvement research.

Key words: salt stress, plant growth promoting rhizobacteria, bio-organic NPK fertilizer, salt tolerance, endogenous hormone
