Plant stress is characterized as a condition that adversely impacts growth and development, perhaps causing injury or resulting in mortality. Abiotic stress and climate change have multiple consequences and significantly threaten the sustainability and productivity of agricultural systems. In modern agriculture, advantageous microorganisms (bacteria, mycorrhizae, insects, etc.) are integral to sustainable practices in response to numerous abiotic challenges, including salinity, drought, cold, and heat, which significantly impact crop productivity. Bacteria benefit advantages from their capabilities in N2-fixation, phosphate solubilization, and the synthesis of siderophores, indole acetic acid (IAA), cytokinins, and ACC (1-aminocyclopropane-1- carboxylate) deaminase. Rhizobacteria are advantageous bacteria residing in plant root exudates, significantly contributing to plant growth and resilience against abiotic stress factors. Plant growthpromoting rhizobacteria (PGPR) are utilized for the enhancement, multiplication, and biological regulation of growth and development in horticultural plants. These plant growthpromoting rhizobacteria are significant for their capacity to mitigate the adverse impacts of numerous abiotic stress factors including drought, salinity, and heavy metal contamination, on plant growth and development. The application of PGPR in sustainable agriculture is a promising strategy to mitigate the challenges associated with abiotic stres factors. The diverse mechanisms through which PGPR alleviate the detrimental impacts of abiotic stres factors, such as the synthesis of phytohormones, osmoprotectants, and the modulation of the antioxidant defense system, render them an invaluable asset for enhancing crop performance and safeguarding food security amid environmental challenges.
