Abstract Climate change has exacerbated the effects of abiotic stresses on plant growth and productivity. Drought is one most important stress factors that interfere with development. Plant selection breeding as well genetic engineering methods used to improve crop drought tolerance are expensive time consuming. Plants use a myriad adaptative mechanisms cope adverse including association beneficial microorganisms such promoting rhizobacteria (PGPR). Inoculation roots different PGPR species been shown promote through variety interconnected physiological, biochemical, molecular, nutritional, metabolic, cellular processes, which include enhanced growth, root elongation, phytohormone production or inhibition, volatile organic compounds. Therefore, colonization by an eco-friendly agricultural method Notably, processes regulated can enhance tolerance. This review addresses current knowledge how affects development describes trigger responses at morphological, molecular levels.

The recent literature indicates that plant growth-promoting bacteria (PGPB) employ a range of mechanisms to augment plant's ability ameliorate salt and drought stress. These include synthesis auxins, especially indoleacetic acid, which directly promotes growth; antioxidant enzymes such as catalase, superoxide dismutase peroxidase, prevents the deleterious effects reactive oxygen species; small molecule osmolytes, e.g., trehalose proline, structures water content within bacterial cells reduces turgor pressure; nitrogen fixation, improves exopolysaccharides, protects from loss stabilizes soil aggregates; antibiotics, stress-debilitated plants pathogens; enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, lowers level ACC ethylene in plants, thereby decreasing stress-induced senescence. Many reports overcoming these stresses indicate most successful PGPB possess several mechanisms; however, involvement any particular mechanism protection is nearly always inferred not proven.

Agriculture has a lot of responsibility as the rise in world's population demands more food requirements. However, than one type biotic and abiotic stress continually impacts agricultural productivity. Drought is major that significantly affects productivity every year plants undergo several morphological, biochemical, physiological modifications, such repressed root shoot growth, reduced photosynthesis transpiration rate, excessive production reactive oxygen species (ROS), osmotic adjustments, modified leaf senescence regulating signaling pathways. Such modifications may permanently damage plants; therefore, mitigation strategies must be developed. The use drought resistant crop cultivars expensive labor-intensive with few advantages. exploiting plant growth promoting rhizobacteria (PGPR) proven alternative numerous direct indirect PGPR confers induced systemic tolerance (IST) mechanisms response to via multiple mechanisms, including alteration architecture, maintenance high relative water content, improvement phytohormones, exopolysaccharides, ACC deaminase, carotenoids volatiles, induction antioxidant defense system, stress-responsive gene expression. commercial application bioinoculants or biostimulants will remain contingent on robust strain selection performance under unfavorable environmental conditions.
