This mechanism is a recent indirect mech- anism of action of PGPR. In addition, PGPR can protect plants from deleterious effects of environmental stress like flooding, drought, salinity, heavy metals, and so on. Chickpea (Cicer arietinum L.) is a major food legume and an important source of protein in many countries. In addition, it is also widely used as fodder and green manure. Chickpea is one of the most important legume crops for human nutri- tion grown in arid and semiarid regions and is considered to be a salt-sensitive species (Ashraf and Waheed 1993). Cultivars grown in India are either native (desi) types char- acterized by smaller, angular, pigmented seeds, or Mediter- ranean (kabuli) types with larger, rounded seeds which lack pigmentation. Because the genus is indigenous to arid areas, some genotypes may have a degree of salt adaptation (Garg and Singla 2004). Hence, selection and implementation of biotechnological approaches can improve economic yield under saline conditions. The objective of this study was to screen out native strains of PGPR from the saline soils of Gujarat that are able to tolerate salinity and use their ability to promote the growth of chickpea. |
