- Abstract
[Objective] To explore the rhizosphere soil and endophytic microbial community composition and structure of the extremely salt-tolerant plant Halostachys capsica in the saline-alkali environment of Xinjiang. [Methods] 16 S rDNA and ITS high throughput sequencing technology were used in this project to determine and analyze the structure and diversity of endophytic microbial community in rhizosphere soil and leaves of salt panicle. [Results] The results showed that the dominant bacteria in the rhizosphere soil bacterial community at the level of the gate were Actinobacteria, Proteobacteria, and Gemmatimonadetes. The dominant bacterium in the rhizosphere was Ascomycota. At the level of the gate, the dominant bacteria in the endophytic bacterial community of the leaves of the leaves were Cyanobacteria, Actinobacteria, Proteobacteria, and a dominant bacterium in endophytic fungi was Ascomycota. According to the Alpha diversity index analysis, the Shannon and Simpson indices of YS1 were the highest in the three soil samples. Namely, the microbial community diversity was higher than the other two samples. [Conclusion] Among the three leaf samples, the Shannon, Simpson and other indexes of YP3 were the highest, that was, the microbial community diversity was higher than the other two samples. The microbial community diversity in the rhizosphere soil of Halostachys capsica was higher than that in the endogenous microbial community. To sum up, the analysis of microbial community composition in rhizosphere soil and leaves of Halostachys capsica provides scientific basis for further study of the correlation between microbial community and its resistance to stress in arid and saline-alkali habitats by PGPR
