摘要: 基于Illumina Miseq高通量测序技术分析了湘黔桂三地野生多花黄精(Polygonatum cyrtonema Hua.)内生真菌、根际土真菌的群落组成及多样性。获得真菌ASVs共3 188条,经聚类涉11门33纲85目166科320属375种真菌,真菌类别主要为子囊菌门(Ascomycota)、担子菌门(Basidiomycota)。在属水平上,根际土真菌贵州样品优势属为Cladophialophora、外瓶柄霉属(Exophiala)等,湖南为Archaeorhizomyces、被孢霉属(Mortierella)等,广西为镰刀属(Fusarium)、Saitozyma等;内生真菌贵州优势属为外瓶柄霉属、粉褶菌属(Entoloma)等,湖南为地星属(Geastrum)、被孢霉属等,广西为镰刀属、Saitozyma等。α多样性分析显示,湘黔桂三地多花黄精药用部位块茎内生真菌、根际土真菌群落的多样性和丰富度均有较大差异;PCoA及UPGMA聚类结果显示,三地间的真菌群落组成差异较大;PICRUSt 2分析预测表明,内生真菌及根际土真菌参与多条代谢途径及黄精多糖等活性物质生成。

Abstract: The community composition and diversity of endophytic fungi and rhizosphere soil fungi of wild Polygonatum cyrtonema Hua. from Hunan Province, Guizhou Province and Guangxi Zhuang Autonomous Region was analyzed based on Illumina MiSeq high-throughput sequencing technology. A total of 3 188 ASVs were obtained in all samples, and were divided into 11 phyla, 33 classes, 85 orders, 166 families, 320 genera and 375 species. Fungi mainly belonged to Ascomycota and Basidiomycota. At the genus level, the dominant genera of rhizosphere fungi were Cladophialophora and Exophiala in Guizhou Province, Archaeorhizomyces and Mortierella in Hunan Province, and Fusarium and Saitozyma in Guangxi Zhuang Autonomous Region; the dominant genera of endophytic fungi were Exosporium, Entoloma, etc. in Guizhou Province, while they were Geastrum, Mortierella, etc. in Hunan Province, and they were Fusarium, Saitozyma, etc. in Guangxi Zhuang Autonomous Region. The alpha diversity analysis showed that the diversity and richness of endophytic fungi and rhizosphere soil fungi communities in the medicinal parts of Polygonatum cyrtonema Hua. from these three provinces(region) were significantly different. The results of PCoA and UPGMA clustering showed that the composition of fungal communities in three areas was quite different; PICRUSt 2 predictive analytics showed that endophytic fungi and rhizosphere soil fungi were involved in multiple metabolic pathways and the production of active substances such as polysaccharides of Polygonatum cyrtonema Hua.
