Plant growth-promoting rhizobacteria (PGPR) are free-living bacteria which actively colonize plant roots,
exerting beneficial effects on plant development. The PGPR may (i) promote the plant growth either by
using their own metabolism (solubilizing phosphates, producing hormones or fixing nitrogen) or directly
affecting the plant metabolism (increasing the uptake of water and minerals), enhancing root devel
opment, increasing the enzymatic activity of the plant or “helping” other beneficial microorganisms to
enhance their action on the plants; (ii) or may promote the plant growth by suppressing plant pathogens.
These abilities are of great agriculture importance in terms of improving soil fertility and crop yield, thus
reducing the negative impact of chemical fertilizers on the environment. The progress in the last decade
in using PGPR in a variety of plants (maize, rice, wheat, soybean and bean) along with their mechanism
of action are summarized and discussed here.
