Abstract
Plant growth-promoting bacteria (PGPB) have become more important to the production of sustainable agriculture during the past few years. Numerous crops have been reported to contain features that support plant growth, such as nitrogen fixation, phosphate solubilization, phytohormone formation, siderophore production, and antibacterial activity. Production of biofertilizers and biopesticides is the need of the hour to feed the population in an eco-friendly manner. A negative impact of climate change has been seen on crop yield and plant development. Utilizing microorganisms that produce 1-aminocyclopropane-1-carboxylate (ACC) deaminase is one of the key ways to reduce environmental impacts. Stress-induced ethylene resulting from abiotic stresses is devastating for plant growth. Plants are more resilient to abiotic stresses and can tolerate harsh environmental conditions owing to bacteria that produce ACC deaminase. With a focus on ACC deaminase activity, this chapter illustrates the function of PGPB in stimulating plant growth and development.
