Abstract
Bacterial communities play an important role in nutrient cycling in riverine wetland ecosystems, and the study of rhizosphere microbial community composition of different plants is of great scientific significance in revealing the relationship between microorganisms and plant interactions in riverine wetlands. In this study, samples were collected from four plant congeries dominated by Artemisia argyi (AH), Acorus calamus (CP), Miscanthus sacchariflorus (DC), and Paspalum distichum (QB), respectively. High-throughput sequencing technology was employed to investigate the rhizosphere microbial community structures associated with these distinct plant species. The results showed that soil water content could effectively regulate the functional diversity of soil microbial communities. Different plant congeries types significantly affected soil bacterial community diversity, and at the phylum level, both Proteobacteria and Acidobacteria were absolutely dominant groups, followed by Bacteroidetes. At the genus level, Flavobacterium, Sphingomonas, Gp6 and Gp4 were the dominant bacteria in the rhizosphere soil of plants along the river. Soil pH, water content, NO3-N, NO2-N and TOC were the main factors affecting the composition of microbial communities. This study broadens our understanding of the composition of rhizosphere microbial communities in the river buffer zone, and provide data support for river ecological environment protection.
期刊介绍:
World Journal of Microbiology and Biotechnology publishes research papers and review articles on all aspects of Microbiology and Microbial Biotechnology.
Since its foundation, the Journal has provided a forum for research work directed toward finding microbiological and biotechnological solutions to global problems. As many of these problems, including crop productivity, public health and waste management, have major impacts in the developing world, the Journal especially reports on advances for and from developing regions.
Some topics are not within the scope of the Journal. Please do not submit your manuscript if it falls into one of the following categories:
· Virology
· Simple isolation of microbes from local sources
· Simple descriptions of an environment or reports on a procedure
· Veterinary, agricultural and clinical topics in which the main focus is not on a microorganism
· Data reporting on host response to microbes
· Optimization of a procedure
· Description of the biological effects of not fully identified compounds or undefined extracts of natural origin
· Data on not fully purified enzymes or procedures in which they are applied
All articles published in the Journal are independently refereed.
