Screening of root nodule endophytes isolated from native legumes of arid regions of India for their multiple PGP traits

Plants growing in inhospitable environment may have association with useful microbes that help them to withstand harsh conditions like poor and degraded soil, high temperature and high salinity. Isolation and screening of isolates from plants of such habitats showing plant growth promoting traits (PGP) would be useful to enrich the bank of agriculturally important microbes. In present investigation more than one hundred isolates were obtained from root nodules of ten native legumes growing in arid regions of Indian Thar desert.
