Rhizosphere and their role in plant-microbe interaction

Abstract

Plant growth promoting rhizobacteria (PGPR) plays an important role in sustainable agriculture. These microbes directly or indirectly associated with the plants for growth promotion, disease management and yield enhancement. Genotypes and diversity of individual plants influences the composition of the associated communities. Microbial population of PGPR present in the rhizosphere depends upon the amount and composition of root exudates. The molecules present in the root exudates act as signaling molecules and helps in microbe interaction. This chapter describes the role of root exudates and mode of plant -microbe interaction in the rhizosphere. © 2015 by Nova Science Publishers, Inc. All rights reserved.
