| 中文摘要:目的 揭示乌头内生细菌的菌群组成及其与生物碱含量的相关性。方法 运用高通量测序分析不同产地乌头叶、茎和根组织内生细菌的16S rDNA V4区，基于测序结果进行内生细菌的多样性分析、物种分类、差异及相似性分析。运用高效液相色谱法分析不同产地乌头叶、茎和根组织乌头类生物碱含量，并对乌头各组织的内生细菌相对丰度和生物碱含量之间进行相关性分析。结果 乌头内生细菌主要由4门，9纲，16目，36属组成；不同产地乌头的内生细菌丰度和多样性均存在差异，但核心菌群组成相似，以变形菌门（Proteobacteria）占主导；共发现6种操作分类单元（operational taxonomic units，OTU）与乌头根组织生物碱含量之间存在相关性。结论 不同产地乌头内生细菌组成存在差异但核心菌群相似，部分内生细菌丰度与生物碱含量之间显著相关。 |

| Abstract:Objective To reveal the composition of endophytic bacteria in Aconitum carmichaelii Debx. and the correlation with alkaloid content.Methods The high-throughput sequencing was used to analyze 16S rDNA V4 regions of endophytic bacteria in the leaf, stem, and root tissue of A. carmichaelii Debx., and the diversity analysis, species classification, and different and similar analysis of endophytic bacteria were conducted based on the sequencing results. Alkaloid content in leaf, stem, and root tissue of A. carmichaelii Debx. were detected by high performance liquid chromatography. Correlation between the relative abundance of endophytic bacteria and the alkaloid content in different tissues of A. carmichaelii Debx. was analyzed.Results Endophytic bacteria of A. carmichaelii Debx. were mainly composed of 4 phyla, 9 classes, 16 orders, and 36 genera. The abundance and diversity of endophytic bacteria in A. carmichaelii Debx. were different, but the composition of core flora was similar with Proteobacteria predominating. Six operational taxonomic units (OTU) were found correlated with alkaloid content in root tissues of A. carmichaelii Debx..Conclusion The composition of endophytic bacteria in A. carmichaelii Debx. From different regions was different, but the core flora was similar. The abundance of partial endophytic bacteria and alkaloid content were significantly correlated. |
