摘要

植物根瘤菌群落对植物的健康生长有着至关重要的影响,而每种根瘤菌群落都有其特定的微生物群落。中华山茶(Camellia sinensis cv. Shifocui)是一种分布于安徽省大别山区的茶树。它具有产量高、品质好、抗寒性强、氨基酸含量高等特点。该研究首次利用16S rRNA高通量测序技术和生物信息学方法探讨了耐寒茶树石佛翠根瘤菌群落的特征和功能,为根瘤菌资源的开发利用提供了重要依据。中生茶树Shifocui根瘤菌群中的优势菌门为蛋白菌门、绿僵菌门、酸性菌门和放线菌门。网络分析显示,中华实生菌根瘤菌群之间存在明显的正相关和负相关关系,其中Candidatus _ Xiphinematobacter、Acidobacteriale、Bradyrhizobium、Subgroup _ 2、Candidatus_Udaeobacter、Gemmataceae和Gaiellales是相互作用网络中的重要节点。FAPROTAX 的功能预测表明,中华实生菌富含化合异养菌、纤维素水解菌和氧化异养菌,表明其根瘤菌群中富含优势菌群,在植物生长发育过程中发挥着重要作用。这些结果为探索中华茶树与根瘤微生物的相互作用机制奠定了基础,为茶树微生物资源的开发利用提供了研究依据。

Characteristics and Functions of Rhizosphere Bacterial Communities of Camelli sinensis cv. Shifocui with Cold Resistance Characteristics in Anhui Province, China.

The rhizosphere bacterial community of plants has a crucial effect on healthy plant growth, and each rhizosphere has a specific microbial community. Camellia sinensis cv. Shifocui (C. sinensis cv. Shifocui) is a tea plant distributed in the Dabie Mountains of Anhui Province. It has the characteristics of high yield, good quality, strong cold resistance, and a high amino acid content. This study was the first to use 16S rRNA high-throughput sequencing technology and bioinformatics methods to explore the characteristics and functions of the rhizosphere bacterial community of the cold-tolerant tea tree C. sinensis cv. Shifocui, providing an important basis for the development and utilization of rhizosphere microbial resources. The dominant phylum in the rhizosphere microbes of the C. sinensis cv. Shifocui rhizosphere microorganisms were Proteobacteria, Chloroflexi, Acidobacteriota, and Actinobacteria. Network analysis showed significant positive and negative correlations among the rhizosphere bacterial groups of C. sinensis cv. Shifocui, among which Candidatus _ Xiphinematobacter, Acidobacteriale, Bradyrhizobium, Subgroup _ 2, Candidatus_Udaeobacter, Gemmataceae, and Gaiellales were notable nodes in the interaction networks. Functional prediction of FAPROTAX indicated that C. sinensis cv. Shifocui was rich in chemoheterotrophic, cellulose hydrolysis, and oxidative heterotrophic conditions, indicating that the dominant bacterial flora was enriched in its rhizosphere microbes and played an important role in plant growth and development. These results lay a foundation for exploring the mechanism of interaction between C. sinensis cv. Shifocui and rhizosphere microorganisms and provide a research basis for the development and utilization of tea plant microbial resources.
