Interaction of plant growth promoting rhizobacteria (PGPR) with host plants is an intricate and interdependent relationship involving not only the two partners but other biotic and abiotic factors of the rhizosphere region. Survival and establishment of PGPR in the rhizosphere is a major concern of agricultural microbiologists. Various factors that play a determining role include the composition of root exudates, properties of bacterial strain, soil status, and activities of other soil microbes. This review focuses on the different components that affect root colonization of PGPR and the underlying principles behind the success of these bugs to tide over the unfavorable conditions.
