Role of plant growth promoting rhizobacteria as ameliorating agent in saline soil

摘要

Abiotic stress factors severely affect the crop plant growth, yield and productivity in the semiarid areas. Though, salt stress is one of the important reasons to reduce crop growth and productivity. High salt in soil is reason to produce critical conditions for plant survival. A number of scientists focus their research to identify tolerance mechanisms in plants under saline soil, although utilization of this information limited to improve crops. In recent years, number of scientist identified tolerance mechanism induced by Plant Growth Promoting Rhizobacteria (PGPR) in crop plants under saline conditions. PGPR Identification and exploitation is proving to be new alternatives against salt stress. Although, PGPRs mechanism of action is not understood. PGPRs application increases water and nutrient uptake and improve phytohormone production. The main aim in this review is to illustrate role of PGPRs as ameliorating agent in crop plant under saline soil.
