Abstract:
:We found high diversity of vegetative compatibility (vc) types in native populations of the chestnut blight fungus, Cryphonectria parasitica, in Japan and China; almost every isolate was in a unique vc type. In Japan we found 71 vc types in a sample of 79 isolates pooled from six populations. Within two populations in China, all isolates (n=28 and 11) had unique vc types; we found 15 vc types among 25 isolates in a third Chinese population where multiple isolates were collected from some trees. None of the isolates from China and only three isolates in the 71 vc types from Japan were compatible with any of 64 vc type testers from Europe, which have known vegetative incompatibility genotypes. To our knowledge this is the first report of vc type diversity for C. parasitica in Japan or of any comparisons of vc types between Asia and Europe. The most significant result of this survey is the identification fungal isolates for expanding knowledge of the genetics of vegetative incompatibility.
