| Abstract |
|
Recently, the oak wilt diseases especially on Quercus mongolica, have been increasing in various districts of Korea. A collection of 38 strains of the oak wilt pathogen Raffaelea qeurcus-mongolicae and R. quecivora isolated from Quercus spp. in Korea and Japan was characterized by β-tubulin gene sequence and randomly amplified polymorphic DNA (RAPD) analysis. In cluster analysis based on β-tubulin gene sequence the strains were divided into 4 clusters, of which clusters 2 and 4 were composed of Japanese strains except for one Korean strain. RAPD analysis showed that they were also effectively differentiated by a strong RAPD fragments. On the basis of the two genetic analysis, significant differences were detected between Korean strains and Japanese strains. |
