Plant Growth-Promoting Rhizospheric Microbes for Remediation of Saline Soils

摘要: Salinity is responsible for lowering the quality of soil and reducing agricultural productivity, continuously increasing area marginal lands across globe. Among biological solutions, application rhizobacteria has emerged as effective strategy promoting plant growth enhancing fertility saline soil. Various direct indirect growth-promoting attributes including phytohormones, exopolysaccharides, osmolytes, antioxidants, 1-aminocyclopropane-1-carboxylate (ACC) deaminase production help to combat negative impact salinity on plants. Indirect mechanisms such synthesis hydrogen cyanide (HCN), antibiotics hydrolytic enzymes in inhibiting phytopathogens conditions. These beneficial microbes also improve structure soil, rejuvenating their productivity index. Henceforth, identification selection halotolerant studying involved salt tolerance would provide a better future designing amelioration strategies soils.
