Plant growth promoting rhizobacterium

Microbial interactions elicit a range of host plant responses from antagonistic or neutral reactions to beneficial reactions that confer enhanced fitness. Here we describe properties of the newly discovered P. fluorescens strain GM30 isolated by us from the Populus deltoides rhizosphere. Pseudomonas sp. GM30 was found to colonize the roots of Arabidopsis host plants and induce proliferation in lateral roots. Additionally colonization of host roots resulted in enhanced resistance to pathogen attack when challenged with the pathogen Pseudomonas syringae DC3000.
