Abstract
In October 2022, Erysiphe powdery mildew from the section Typhulochaeta was found on Quercus aliena for the first time in Korea. Based on morphological characteristics and molecular-phylogenetic analysis of the internal transcribed spacer region (ITS) and large subunit (LSU) gene sequences of the rDNA, the fungus was identified as Erysiphe japonica var. japonica. This is the first report of E. japonica var. japonica in Korea and the third report of this mildew on Q. aliena, with this current fungus-host association spreading to China and Japan. Based on Korean samples, this study provides detailed morphology and molecular phylogeny of E. japonica var. japonica.
2022年10月，在韩国首次在栎树上发现了斑疹白粉病。基于形态学特征和rDNA内部转录间隔区(ITS)和大亚基(LSU)基因序列的分子系统发育分析，鉴定该真菌为Erysiphe japonica var. japonica。这是韩国首次报道的日本血吸虫变种，也是第三次报道的这种真菌，目前这种真菌与宿主的联系正在向中国和日本蔓延。本研究以韩国样品为基础，提供了粳稻变种(e.japonica var. japonica)的详细形态和分子系统发育。
期刊介绍：
This peer reviewed, highly specialized journal covers forest pathological problems occurring in any part of the world. Research and review articles, short communications and book reviews are addressed to the professional, working with forest tree diseases caused by fungi, bacteria, nematodes, viruses, and phytoplasms; their biology, morphology, and pathology; disorders arising from genetic anomalies and physical or chemical factors in the environment. Articles are published in English.
Fields of interest: Forest pathology, effects of air pollution and adverse environmental conditions on trees and forest ecosystems.
