植物促生菌提高植物耐盐性的研究进展
Research Progress of Plant Growth-Promoting Bacteria in Salt Tolerance of Plants
摘要
Abstract
Soil salinity leads to a sharp loss in crop yield has become a major threat to global agroecosystems.Many strategies have been implemented in current production to remediate saline-alkali land and restore its productivity.Among them,the utilization of Plant growth promoting bacteria(PGPB)is considered as a promising bio-fertilizing method for soil reclamation,suitable for reclaiming saline-alkali soil and enhancing crop productivity.Salt-tolerant PGPB utilizes a variety of mechanisms that affect physiological,biochemical and molecular responses in plants to cope with salt stress.These mechanisms include osmotic adjustment by ion homeostasis and osmolyte accumulation,protection plants from free radicals by the formation of free radicals scavenging enzymes,induction of oxidative stress and maintenance of plant growth by the synthesis of phytohormones and other metabolites.In this review,various mechanisms used by PGPB to promote plant growth under salt stress were discussed,and the recent progress and prospects of PGPB in improving plant salt stress were emphasized.关键词
