Stress mitigation strategies of plant growth-promoting rhizobacteria: Plant growth-promoting rhizobacteria mechanisms

One of the major challenges that world is facing currently inadequate amount food production with high nutrient content in accordance increase population size. Moreover, availability cultivable area fertile soil reducing day by owing to ever increasing population. Further, water scarcity and expensive agricultural equipment have led use agrochemicals untreated water. Excessive chemical fertilizers crop yield resulted deleterious effects on environment, health economy, which can be overcome a great extent employing biological fertilizers. There are various microbes grows rhizospheric region plants known as plant growth-promoting rhizobacteria (PGPR). PGPR act direct indirect modes stimulate growth improve stress reduction plants. PGPRs used for potential agriculture practices having wide range benefits like nutrients content, healthy crops, phytohormones, prevention from heavy metal conditions yield. This review reports recent studies improvement strategies using describes mechanisms involved. The its allies pave way sustainable development towards commercialization bacteria.
