Abstract :

Genetic diversity of plant growth-promoting rhizobacteria (PGPR) associated with rice plant (Oryza sativa L.) in rhizospheric soil collected from the rice fields in Sivagangai, Tamilnadu has been analyzed in the present study. A total of 13 strains among 961 isolates were randomly selected for studies based on the genus specific confirmation by the Pseudomonas specific primer. Phylogenetic analysis based on 16S rDNA gene sequences generated 3 clusters showing more than 90% of boot strap value.
