英文摘要	Soil salinity and desertification are seriously threatening the ecological environment of Ebinur Lake Wetland. Myxobacteria are the main soil microbes in this wetland. However, it is still unclear if the myxobacterial community structure and diversity can improve the ecological environment of Ebinur Lake Wetland by regulating soil nutrient cycling. Therefore, based on high-throughput sequencing of 16SrRNA gene technology, the composition, function, and diversity of the myxobacterial community in the rhizosphere of Tamarix chinensis Lour in Ebinur Lake Wetland were studied. Rhizosphere soil samples were collected from 10 sampling sites (S1, S2, S3, S4, S5, S6, S7, S8, S9, and S10) for three months (April, July, and October) to explore the main biotic and abiotic factors affecting the diversity and functions of myxobacterial communities. The results revealed that diversity of myxobacterial communities was mainly influenced by the seasons. The diversity of myxobacterial communities was significantly higher in the month of July, as compared to April and October. FAPROTAX functional prediction revealed that, in addition to predation or parasitic functions, myxobacteria were mainly involved in ecological functions, such as nitrite respiration, nitrite ammonification, and nitrogen respiration. The Spearman correlation analysis of the diversity and function of myxobacteria and bacteria showed that there were significant positive correlations between myxobacteria diversity, function, and bacterial diversity. The co-occurrence analysis of myxobacteria and bacterial networks showed that over time, myxobacteria interacted differently with different bacterial networks and jointly regulated the microbial community in the rhizosphere of Tamarix chinensis Lour through predation or cooperation. The redundancy analysis of soil physicochemical factors as well as the myxobacterial community showed that electrical conductivity, exchangeable calcium, and exchangeable potassium were the most important abiotic factors affecting the diversity, structure, and function of the myxobacterial community. These results reveal that myxobacteria may play important roles in degrading nitrogen compounds and regulating the activity of soil microorganisms. This study provides theoretical support for the ecological restoration of Ebinur Lake Wetland and lays the foundation for the future development and utilization of myxobacteria resources.
