Plant growth-promoting rhizobacteria as biological control agents

Abstract

After describing the steps involved in root colonization and the role of plant growth-promoting rhizobacteria (PGPR), there is further discussion of the relation between growth promotion and biological control and the mechanisms by which rhizobacteria exhibit biological control. These mechanisms of antibiosis, competition, parasitism, siderophores and cyanide production, are dealt with in greater detail. Future likely directions of research into biological control by PGPRs are outlined. -J.W.Cooper
