Rhizosphere colonization by plant-beneficial Pseudomonas spp.: thriving in a heterogeneous and challenging environment.

Abstract

This chapter focuses on the establishment of the relationship with a special emphasis on the plant-driven nutrient heterogeneities of the rhizosphere and on some competitiveness enhancing traits, involved in the success of several plant-beneficial Pseudomonas spp. strains. It is established that determining plant traits supporting bacterial colonization of the rhizosphere is as crucial as studying bacterial traits, and may lead to new plant varieties optimized for PGPR colonization. Large-scale development of efficient plant-beneficial Pseudomonas spp. will be achieved by embracing an integrated vision of the rhizosphere.
