Abstract
|
|
|
|
In Korea, powdery mildew has been observed on Quercus rubra , commonly called the northern red oak tree. Based on its morphological and molecular phylogenetic analyses, the fungal agent was identified as Erysiphe quercicola, but it was distinct from the other four Erysiphe species, specialized to Quercus species. This is the first confirmed report on the identity of powdery mildew found on Q. rubra in Korea. This finding can help understand the host expansion of E. quercicola and the biodiversity of powdery mildew on Quercus species.
