Diversity Analysis of Endophytic Bacterial Resources in Plant Remediation of Heavy Metals

Abstract

Endophytic bacteria are bacteria that are designated to colonize various tissues and organs of healthy plants. Infected host plants do not exhibit external diseases, and heavy metal tolerant endophytic bacteria exist in various hyperaccumulating plants. In our study, the population density of endophytic bacteria is the highest in the root tissue, taken together, plant endophyte types are very rich in ramie. Our results showed that Proteobacteria are the primary microbial flora in the endophytic bacteria of all ramie varieties. The diversity of endophytic bacteria in two species of ramie, which is LSCM and 1407, was higher than that in other species. The results showed that there are differences among different species in ramie. There are differences in endophytic bacteria in different parts of the same species in ramie. provide support for Transfer patterns and persistence of endophytic bacteria after host plant colonization in the study. This paper expects to conduct simulation studies on the interaction between various endophytic bacteria and plant joint systems in natural environments, explore different endophytic bacteria and plant joint remediation systems, and provide guidance for practical applications. © The Authors, published by EDP Sciences.
