Analysis of genetic diversity among fluorescent Pseudomonads isolated from groundnut rhizosphere

Fluorescent Pseudomonads as plant Growth Promoting Rhizobacteria (PGPR) has played a significant role in plant development with decrease in the severity of several fungal diseases. The present research work focus on characterization of genetic diversity of isolated 24 fluorescent Pseudomonads isolated from different rhizosphere of the groundnut in the Rayalaseema region of Andhra Pradesh. Genetic diversity was analyzed by RAPD markers and among the studied 12 primers; eight primers produced 100% polymorphic bands while the OPC12 primer showed a monomorphic band. A total number of 87 amplified bands were identified, of which 80 polymorphic bands were noted and the PIC value ranged from 0.12 to 0.36 for polymorphic markers.The dendrogram analysis divided the isolates into two major and two minor clusters. The knowledge gathered here about the genetic diversity of fluorescent Pseudomonads associated with the ground soil rhizosphere helps to understand their role and potential use in sustainable agriculture.
