Novel microsatellite markers reveal multiple origins of Botryosphaeria dothidea causing the Chinese grapevine trunk disease

Botryosphaeria dothidea causes diseases in many different hosts worldwide. This species has become the most prominent fungal taxon causing grapevine trunk disease in China, with a recent disease outbreak. To reveal the genetic diversity and explore the origin of B. dothidea, six novel microsatellite markers were developed and used for the genotyping of 151 isolates obtained from China and overseas. The results demonstrated the high genetic …
