Plant–bacterial interactions in the rhizosphere are complex and determine the plant health,
productivity and soil fertility. The Plant Growth Promoting bacterial strains were isolated from the
rhizospheric soil of the cotton plant from various places of Haryana, India. One of the most promising
isolate exhibiting maximum PGP traits was identified as Pseudomonas fluorescens based on the
biochemical characterization, phenotypic microarray analysis and 16S rDNA sequencing. The isolate
was initially screened on the basis of the seed germination assay and was then screened in vitro for
their plant growth promoting traits like production of indoleacetic acid (IAA), ammonia production
(NH3), hydrogen cyanide (HCN) production, siderophore production, phosphate solubilization,
ACC deaminase activity and acetylene reduction activity (ARA). The isolate exhibited positive results
for ammonia and siderophore production and phosphate solubilization. The isolate also showed
acetylene reduction activity (ARA). The results indicated that P. fluorescens has significant potential
when applied to soil–plant system to uncover its efficacy as effective PGPR.
