| 中文摘要: |
| 在中国和北美大陆分别收集53和15株高卢蜜环菌Armillaria gallica菌株，并用ISSR（inter-simple sequence repeat）分子标记对这些菌株进行了亲缘关系及系统发育分析。结果表明：中国和北美大陆的A. gallica因地理隔离产生明显的遗传分异，在系统发育树上分别形成了各自的进化分支；北美大陆的分支内部遗传分化尚不明显，而中国的进化分支遗传分化程度相对较大且更为古老，中国菌株可能是两个大陆A. gallica的祖先株系。 |
| 英文摘要: |
| Fifteen and 53 isolates of Armillaria gallica were collected respectively in North America and China. The phylogeny and genetic relationship of these isolates were analyzed by ISSR-PCR. The results indicated that isolates of North America and those of China showed obvious genetic differentiation caused by geographic isolation, forming different clades in the phylogenetic tree. The genetic differentiation within North American clade was not obvious, but the differentiation within Chinese clade was clear and more ancient. Chinese isolates might be the ancestry of A. gallica in the two continents. |
