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