A comparison of bacterial variability across biogeographic regions based on PGPR

DOI: 10.22161/ijeab.66.8

Abstract:
Plants are sessile organisms that experience abiotic stresses like sediment salinity, drought, and extreme temperatures. In light of our growing population and increasing demand for better nutrients and commercial quality foods, optimizing the use of our natural resources is essential to ensuring food security.Enhancing PGPR using modern tools and techniques of biotechnology can greatly contribute to achieving sustainable agriculture, by improving soil fertility, plant tolerance, crop productivity, and maintaining a balanced nutrient cycling. Plant rhizospheres could contribute to the development of robust plant growth-promoting (PGP) activities and stress tolerance capabilities under drought conditions. They enhance the adaptation of plants for different desertification environments because they are diverse and functionally redundant (PGPR). In addition to soil properties and plant species, there are a variety of biotic and abiotic factors that influence their composition and abundance. In this review article, we learn how Bacterial diversity is influenced by soil environment and geophysical conditions.
