Potential Role of PGPR in Agriculture

  • P. Parvatha Reddy
Chapter

Abstract

Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth by a wide variety of mechanisms such as phosphate solubilization, siderophore production, biological nitrogen fixation, rhizosphere engineering, production of 1-aminocyclopropane-1-carboxylate (ACC) deaminase, quorum-sensing (QS) signal interference and inhibition of biofilm formation, phytohormone production, exhibiting antifungal activity, production of volatile organic compounds (VOCs), induction of systemic resistance, promoting beneficial plant–microbe symbioses, interference with pathogen toxin production, acting as bioelicitors (trigger physiological and morphological responses and phytoalexin accumulation in plants), rhizoremediation (resist high concentration of heavy metals such as cadmium, aluminium, etc.), tolerating moisture and salinity stress, etc. The potentiality of PGPR in agriculture is steadily increasing as it offers an attractive way to replace the use of chemical fertilizers, pesticides and other supplements. Recent progress in our understanding on the diversity of PGPR in the rhizosphere along with their colonization ability and mechanism of action should facilitate their application as a reliable component in the management of sustainable agricultural system.
