FUNCTIONAL CHARACTERIZATION AND EVALUATIONOF PLANT GROWTH POTENTIAL IN PGPR’S FROM SOIL

Shweta Tiwari, Anand Kumar.

Abstract
Given increasing environmental contamination with the deterioration of soil health and due to the use of chemical
fertilizers for increasing crop productivity, Plant growth-promoting bacteria or PGPR are being used as this present
as a plant growth promoter and an alternative to chemical fertilizer. Plant rhizosphere is known to be preferred
ecological niche for various types of soil microorganisms due to rich nutrient availability. Plant growth-promoting
rhizobacteria (PGPR) are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants
by several mechanisms like IAA production, siderophore production, phosphate solubilization, etc. Phosphate
solubilizing microorganisms play an important role in supplementing phosphorus to the plants by several
mechanisms like lowering of pH by acid production and ion chelation and thus benefit plant growth and
development. The present study gave insight into the PGPR population from the different soil samples and obtained
an overall 15 isolates. These isolates were then characterized by biochemical and functional criteria. The functional
characterization revealed all the potential properties of the isolates that are necessary for an organism to be an
effective PGPR. The experiment of seed bacterization on wheat seeds demonstrated the efficiency of these isolates
in growth promotions, as all the isolates showed a good growth-promoting trait in the wheat seed germination. The
study concluded that these isolates are very potential PGPRs and hence can be undertaken the consideration to be
used at field scale for crop improvement. A future study could focus on the better functional characterization and
molecular identification of these isolates as well as the application of these isolates on the stress tolerance
experiments.

Key words: Rhizosphere, Crop improvement, PGPR, IAA
