The rhizosphere is a nutrient rich environment, where numerous interactions between plant and microorganisms occur, ranging from mutualism to parasitism. The enrichment of specific microbial populations in the rhizosphere is dependent on the capability of these micro-organisms to utilize root exudates, to effectively colonize the root surface and to interact or compete with other micro-organisms. Analysis of the rhizospheric communities incorporating both established techniques, and recently developed "omic technologies" can now facilitate investigations into the molecular basis underpinning the establishment of plant-microbial interactomes in the rhizosphere. Therefore, the aim of this chapter is to present an overview of bacterial functions enriched in the rhizosphere of different plant species using data obtained from several functional genomics analyses read more ...
