药用杜仲树皮真菌群落的核心真菌组研究

微生物在生态系统中起着重要作用。最近的研究表明,微生物群落具有核心组(分类单元),这些类群对宿主的健康、生长和生产有着重要的影响。基于MetaCoMET与共存网络两种方法对采自湖南、四川和贵州的药用杜仲树皮真菌群落进行了核心真菌组分析。MetaCoMET结果显示,在OTU水平上,核心真菌组共有16个分类单元,优势菌是丛赤壳科一未定真菌,其次为Fusarium pseudensiforme、一种黄丝菌Cephalothecaceae sp.和一种镰刀菌Fusarium sp.等。共存网络分析揭示了11个中枢真菌分类单元。虽然两种方法的分析结果不完全吻合,但在11个中枢真菌上具有较好的一致性。整体而言,特定核心真菌组具有一定的稳定性。研究结果为进一步揭示植物微生物组的功能提供支撑。

Core microbiome of fungi in the bark of medicinal plant Eucommia ulmoides

Microorganisms play important role in the ecosystem. Recent studies have shown that microbial communities have core groups (taxa) that have important implications for host health, growth, and production. Based on MetaCoMET and network co-occurrence methods, the core microbiome analysis of fungi in medicinal Eucommia ulmoides bark collected from Hunan, Sichuan and Guizhou was carried out. The results of MetaCoMET analysis showed that the core microbiome of fungi included 16 taxa at the OTU level. An unclassified fungus of Nectriaceae was dominant, followed by Fusarium pseudensiforme, Cephalothecaceae sp. and Fusarium sp. and so on. Network co-occurrence analysis revealed 11 hub fungal taxa. Although the analysis results of the two methods were not completely coincident, good consistency was displayed for 11 hub fungi. Overall, certain core fungal biome has stability to some extent.
