16S rRNA Phylogenetic Analysis of Heavy Metal Tolerant Plant Growth Promoting Rhizobacteria
2020
Shuchita Verma and Baljeet Singh Saharan
The present study was aimed to characterize the bacterial isolate DDI(I)1 isolated from the rhizospheric soil of Ocimum grown in New Delhi (India). The isolate exhibited multiple plant growth promoting activities namely ammonia production, production of phytohormones, hydrogen cyanide, solubilization of minerals, tolerance against heavy metals, etc. The isolate was morphologically and biochemically characterized and it was found that DDI(I)1 belongs to genus Pseudomonas. Further, 16S rRNA sequencing revealed that the isolate shared 99% homology with Pseudomonas fluorescens.
