Abstract
Plant-growth-promoting rhizobacteria (PGPR) are important microorganisms which are now known for their potent role in plant growth and development. In last decade or so, various PGPR species belonging to a number of genera have been reported to improve crop growth which is often compromised by biotic and abiotic stresses. PGPR directly or indirectly influence plant life by providing access to essential nutrients and secreting bioactive secondary metabolites. These PGPR have the potential to produce bioactive chemical constituents; however, they are little known for their abilities to secrete gibberellins (GAs). Application of such PGPR with exogenous supply of GAs can further enhance crop plant growth even during abiotic stress, while these can act as alternative to eco-friendly fertilizer to enhance crop yield.
