- Abstract
The rhizospheric association of bacteria in terrestrial plants across the hilly region has tremendous potential for plant growth-promotion (PGP) and protection. This is the first study which aims to isolate some rhizo-bacteria from the different rhizospheric soil samples of S. obvallata in The Himalayan region. Genotypic, biochemical and PGP traits shows genetically similar bacteria species to have diverse PGP potential as shown by IAA production of 87.567 μg ml-1 by Bacillus sp. D5 and phosphate solubilization potential 30 mm halo zones are shown by Bacillus sp. D9. Growth of isolates was in the ranges of temperature (0-60 °C), salt (0-20%), which shows their tendencies towards surviving harsh environmental conditions. The isolates were further evaluated on Amaranthus cruentus, which shows a significant improvement in growth compared to control. The novel study finds the bacterial community at high altitudes to survive extreme climatic variability through association with plants by developing a commensalistic relationship with host.
