Plant growth promoting Rhizobacteria: An overview

signal exchange between the host and the bacterium Plant growth and nodulation by rhizobia are promoted by certain rhizobacteria [128, 90, 30] The PGPR can influence plant growth directly through N2 fixation and production of biocontrol agents against soil-borne phytopathogens [66, 92, 70, 110, 15]

Application of Plant Growth Promoting Rhizobacteria (PGPR)

Plant growth promoting rhizobacteria (PGPR) are a heterogeneous group of bacteria that can be found in the rhizosphere, at root surfaces and in association with roots, which can improve the extent or quality of plant growth directly and/or indirectly The interaction between plant and microbes mainly plant growth promoting
