PGPR for protection of plant health under saline conditions

Abstract

The economy of many countries relies on agriculture. Salinity is one of the major constraints that limit crop productivity, particularly in arid and semiarid regions. The development of salt-tolerant crops is not an easy and economical approach for sustainable agriculture, whereas microbial inoculation to alleviate salt tolerance is a better option because it minimizes production costs and environmental hazards. The aim of the present review is to point out the status of salinization and constraints related with it, and to draw the focus on future research strategies for the development of better inoculants in saline-affected regions, particularly in context to the developing countries.
