中国金黄壳囊孢菌的致病性分化及遗传多样性
Pathogenic Differentiation and Genetic Diversity of Cytospora chrysosperma in China
摘要
Abstract
Forty-six Cytospora chrysosperma strains isolated from 31 cities or counties of 11 provinces in China were analyzed for their pathogenicity and genetic diversity.The results showed that there was no significant relationship between the geographical origin and the pathogenicity,but there was a certain relationship between pathogenicity and the host species.The strains isolated from Popular showed stronger pathogenicity than that from non-poplar hosts.The RAPD analysis of genetic diversity divided the C.chrysosperma strains into two groups.The first group included all strains of Beijing,Xinjiang,Liaoning,Shaanxi,Jilin,Qinghai,Gansu and 5 strains of Heilongjiang,2 strains of Shandong,1 strain of Inner Mongolia.The second group included all strains of Sichuan,7 strains of Inner Mongolia and 1 strains of Shandong.The cluster analysis of genetic diversity further divided the strains of the first group into the geographic groups of Beijing,Xinjiang,Liaoning,as well as the Gansu and Qinghai mixed group,the Heilongjiang,Jilin,Qinghai,Shaanxi,and Gansu mixed group.The strains of the second group were divided into the geographic groups of Inner Mongolia and Sichuan.The study indicated that there was an obvious relationship between the the geographical origin and the genetic diversity grouping.关键词
