Growth promoting properties of Mycobacterium and Bacillus on rice plants under induced drought

Management of drought stress through application plant growth promoting rhizobacteria (PGPR) is now considered as an effective strategy in the present scenario altered environmental conditions world. The aims and objectives investigation was isolation, characterization identification some potential microbial resources from drought-affected upland rice fields South Bengal followed by experimentation on effect isolated PGPR induced seedlings. Selected isolates were field rhizospheric soils tested for their activity, phosphate solubilization, nitrogen fixation, IAA production ACC deaminase activity. Then, selected identified 16S rDNA sequencing phylogenetic analysis. Among screened two (isolate 1 isolate 6) showing traits, applied studied germplasm (IR64) to find out influence organisms development under drought. Both showed a positive (through increase germination percentage, root growth, shoot fresh weight dry weight) Isolate 6 species Mycobacterium sp Bacillus respectively molecular taxonomy. Hence, these are expected alleviate nature promotion stress.
