Abstract

The presence of Pleochaeta shiraiana associated with powdery mildew of Celtis sinensis in Korea is dubious, mainly due to incomplete records of earlier workers. To confirm the occurrence of the powdery mildew and the identity of the causal fungus, morphological characteristics of the anamorph and teleomorph from nine samples deposited in KUS (Herbarium in Korea University) were examined by light microscopy. Identification of the fungus was supported by comparing four ITS sequences from Korean samples with two Japanese data. This is the first confirmed report of the powdery mildew associated with P. shiraiana in Korea.

지금까지 우리나라에서 팽나무 뒷면흰가루병 및 병원균 Pleochaeta shiraiana의 존재에 대하여 확실하게 알려지지 않았으므로 이를 확인하기 위하여 고려대학교 표본실에 보존된 9개 시료를 대상으로 병원균의 무성세대와 유성세대의 형태적 특징을 현미경으로 관찰하고 기록하였다. 또한 4개 시료에서 획득한 ITS 염기서열을 일본의 2개 시료에서 알려진 자료와 비교하여 99% 이상의 상동성을 확인하였다. 이로써 P. shiraiana에 의한 뒷면흰가루병이 우리나라에서 발생함을 확인할 수 있었다.
