Abstract
One of the most potential bacteria for plant growth promotion with minimal adverse reactions is Bacillus amyloliquefaciens. The plant growth-promoting (PGP) mechanisms of B. amyloliquefaciens have received a great deal of attention since it is a highly effective biofertiliser and biocontrol agent in agriculture. In this work, we studied B. amyloliquefaciens�s PGP processes as well as the present restrictions on its use in agriculture. Primarily, B. amyloliquefaciens can increase the availability of soil nutrients by increasing the delivery of nitrogen, solubilisation of potassium and phosphate, and the production of siderophores. Subsequently, B. amyloliquefaciens can alter the soil microbial community by increasing the accessibility of minerals and enhancing the environment for plant growth. Additionally, B. amyloliquefaciens can also emit hormones and volatile organic compounds (VOCs) linked to plant cell proliferation and root development, which would enhance plants� ability to absorb nutrients. B. amyloliquefaciens can also help in increasing the plant resistance to biotic stressors caused by soil pathogens by competing for nutrients and functions, creating compounds such cyclic lipopeptides and VOCs that directly combat pathogens and system resistance in the plants. Similar to this, B. amyloliquefaciens inoculation can stimulate plant growth by altering the host plant�s genetic makeup, chemistry, and physical structure to make it more resilient to abiotic stressors. It is additionally suggested that in future research, greater attention should be made to nitrogen absorption processes of plants using improved methodologies in varied soil conditions and locations. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
