Microbial genes involved in interaction with plants

Abstract

Although microbes are quite small in size and invisible to naked eyes, they play significantly huge role compared to bigger organisms. The most important factors behind this significant and indispensable role are the genes present in the bacterial cell. The genes and gene products of bacterial cells provide them the ability to survive in almost every environmental condition whether favorable or unfavorable. In a strict sense, bacterial cells interact with other organisms for their own benefit, but the ultimate result is either beneficial or harmful to plants and human beings. Nitrogen fixation is one of the most significant phenomena of nature, with an annual nitrogen fixation of about 175 million tons. This huge amount of nitrogen fixation is carried out by the nif gene. Another important aspect of bacterial interaction with plant is the transfer of genes of interest to the plant cell by Agrobacterium tumefaciens. © 2019 Elsevier B.V. All rights reserved.
