Abstract
Drought stress is one of the major limiting factors for worldwide crop production. In this regard, plant growth promoting rhizobacteria (PGPR) have been reported to play significant roles. PGPR can mediate drought stress by altering different plant hormone status, mediating water and nutrient capture, inducing accumulation of osmolytes including several compatible organic solutes like sugars, amino acids and polyamines, antioxidants, upregulation or down regulation of stress responsive genes. Rhizobacteria not only have local effects on root health, elongation, and architecture, but can also affect plant root-to-shoot hormonal signaling that regulates leaf growth and other physiological processes of plants. The PGPR induced productions of osmolytes are associated with metabolic adjustments during stress exposure to plants. It is the need of the day to stimulate the commercialization of rhizobacterial inoculants including those that alter plant hormone status for sustaining crop growth and yield.
