Root Exudates Dominate the Colonization of Pathogen and Plant Growth-Promoting Rhizobacteria

Part of the Soil Biology book series (SOILBIOL,volume 52)

Abstract

Plant secretes a large part of photosynthetic products as root exudates to rhizosphere for better growth surrounded by a variety of abiotic and biotic factors. Pathogens and plant growth-promoting rhizobacteria (PGPR) are the most important biotic factors which impact the plant health. How these two groups of microbe compete in the rhizosphere for niches and nutrition is well studied, and the roles of root exudates play between the pathogen and PGPR interaction and competition for colonization are also investigated recently. Plants try their best to recruit beneficial microbes by root exudates when they are needed, while pathogens also made their efforts to recognize the components of root exudates from their hosts. This chapter summarized the recent data referred to the root exudates and rhizosphere, especially the interaction between plant and soil microbes and also raised several aspects which are still limitedly known.
