Description
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
87.567 μg ml-1 by Bacillus sp. D5 and phosphate solubilization potential
30mm halo zones are shown by Bacillus sp. D9. Growth of isolates was in the
ranges of temperature (0-60oC), 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.
