Abstract:
Endophytes not only provide the basic nutrients for plants but also help them to adapt various environmental stresses. The present study is planned to isolate novel endophytic plant growth promoting bacteria from xerophytic grasses. A total number of 8 endophytic bacteria were isolated from xerophytic grasses and reinfection test was done to check its putative endophytic nature. Out of which, 6 turned out to be putative endophytes, which were further screened for plant growth promoting traits. Among all, isolate E2 produced higher amount of IAA (6.8 µg/ml) followed by E13 with 5.3 µg/ml. Thus results suggest that the endophytic isolates, E2 and E13 were found to be the potential tool plant growth promotion in agricultural crops.
