| 摘 要： | 本文基于野生香菇资源的文献以及公共数据库中的序列信息,调查了香菇在我国以及世界范围内的地理分布,同时利用ITS序列进行了遗传多样性分析。结果显示香菇在我国的21个省市有分布,其中对云南、四川和湖北等省香菇资源的研究最为密集。不同菌株的聚类与地域来源有一定的相关性,进一步通过多样性分析显示我国野生香菇的多样性中心分布于西北和西南地区。本文有助于指导我们进行香菇野生资源的调查,进一步挖掘香菇种质资源的多样性。

| Abstract: | The geographical distribution of Lentinula edodes was surveyed from the information of literatures published and nucleic acid databases. The genetic diversity was evaluated based on ITS sequences. The results confirmed that L. edodes was distributed in over 21 provinces or regions in China and L. edodes in Sichuan, Yunnan and Hubei were most frequently studied. There is a strong correlation between the geographic origins of the isolates. The genetic diversity centers were located in southwestern and northwestern China. The investigation may help us to explore germplasm of the fungus. |
