Phylogenetic analysis of Armillaria gallica from North America and China
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 differentiationwithin Chinese clade was clear and more ancient. Chinese isolates might be the ancestry of A. Gallica in the two continents.
