Abstract

Plant growth-promoting rhizobacteria (PGPR) are soil bacteria that colonise the rhizosphere and promote plant growth through a range of mechanisms including organic matter mineralization, biological control of soil-borne diseases, biological nitrogen fixation, and root growth promotion. The ability of PGPR to enhance nutrient bioavailability is a crucial characteristic. Several bacterial species have been reported as P-solubilizing microorganisms, while others, such as those that create siderophores for Fe chelation, have been found to boost the solubility of micronutrients. The increased concentration of soluble macro and micronutrients along the soil-root interface has a beneficial effect on the plant nutrition. Furthermore, several pieces of evidence suggest that culturing plants with PGPR can have considerable physiological and molecular effects on plants (e.g., induction of rhizosphere acidification, up-and down regulation of genes involved in ion uptake and translocation), suggesting that soil biota could stimulate plants to be more efficient in trying to extract nutrients from soil and coping with abiotic stresses. However, the molecular mechanisms behind these events, the signals involved, as well as their potential uses in a sustainable agriculture strategy and biotechnological elements for hypothetical rhizosphere engineering, are all still up for debate.
