[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.
