Bacterial and Fungal Diversity from the Rhizosphere of Plants Wildly Growing in Agricultural Soil Under Unfavourable Environmental Conditions

Abstract

Rhizospheres harbor many beneficial microorganisms interacting with the plant ecosystem. However, in agriculture, there is a tendency to remove any plant that is different from that being cultivated. This work aimed to display the root microbial communities of native vegetation growing wild in agricultural soil. Thus, high-throughput sequencing of culture-independent marker genes was performed for bacteria and fungi from these habitats after a period of high environmental temperatures. With respect to bacteria, results revealed a number of Operational Taxonomic Units (OTUs) ranging from 3210 to 3266. With respect to fungi, the results revealed a number of OTUs ranging from 963 to 973. Information on the composition of the rhizosphere microbial communities favours the understanding of their potential functions and their beneficial effects on the sustainability of the agrosystems.
