【摘要】：【目的】了解羊肚菌白霉病发生对土壤真菌群落结构的影响。【方法】采用Illumina Mi Seq高通量测序技术,对未栽培羊肚菌土壤、正常生长羊肚菌和染白霉病羊肚菌根际土真菌群落结构进行研究。【结果】9个样品共得到393 347条有效序列。未栽培羊肚菌土壤真菌多样性指数和丰度显著大于羊肚菌根际土,染病羊肚菌根际真菌丰度和多样性大于正常生长的羊肚菌,各样品的群落组成和优势类群有较大差异。【结论】羊肚菌栽培后真菌多样性降低,白霉病发生后根际真菌种类增多,土壤真菌群落结构发生变化,优势真菌类群也产生了较大变化。
[Abstract]:[objective] to investigate the effect of Morchella white mold on the community structure of soil fungi. [methods] Illumina Mi Seq high throughput sequencing technique was used to study the community structure of Morchella and Morchella in the rhizosphere soil of uncultivated Morchella. [results] 393,347 effective sequences were obtained from 9 samples. The diversity index and abundance of fungi in uncultivated Morchella soil were significantly higher than those in Morchella root soil, and the abundance and diversity of Rhizosphere fungi in infected Morchella were higher than those in normal growing Morchella. The community composition and dominant groups of each sample were quite different. [conclusion] after the cultivation of Morchella, the diversity of fungi decreased, the species of Rhizosphere fungi increased after the occurrence of white mold, and the community structure of soil fungi changed. The dominant fungal groups have also changed greatly.
