摘要

雪霉(Racodium therryanum)是一种引起针叶树雪枯萎病和种子腐烂的雪霉菌。黄花蓟马的性期尚未发现，但据推测，引起褐叶枯病的刺槐Herpotrichia juniperi是黄花蓟马的性期。在这项研究中，我们使用28S大亚基(LSU) rDNA、18S小亚基(SSU) rDNA、翻译延伸因子1- α (tef1)和RNA聚合酶II第二大亚基(rpb2)进行了系统发育分析。根据形态特征鉴定4株为黄芽孢杆菌;它们与两株杜松组成了一个具有高自举和贝叶斯后验概率值支持的支系。因此，我们得出结论，以前被描述为therryanum的雪霉菌在系统发育上是juniperi。

Snow mold fungus Racodium therryanum is phylogenetically Herpotrichia juniperi.

Racodium therryanum is a snow mold causing snow blight and seed rot in conifers. The sexual stage of R. therryanum has not been found, however, it has been speculated that Herpotrichia juniperi, which causes brown felt blight, is the sexual stage of R. therryanum. In this study, we conducted phylogenetic analysis using 28S large subunit (LSU) rDNA, 18S small subunit (SSU) rDNA, translation elongation factor 1-alpha (tef1), and RNA polymerase II second largest subunit (rpb2). Four isolates were identified as R. therryanum based on their morphological characteristics; together with two strains of H. juniperi, they composed a clade supported by high bootstrap and Bayesian posterior probability values. Therefore, we conclude that the snow mold previously described as R. therryanum is phylogenetically H. juniperi.

期刊介绍： Mycoscience is the official English-language journal of the Mycological Society of Japan and is issued bimonthly. Mycoscience publishes original research articles and reviews on various topics related to fungi including yeasts and other organisms that have traditionally been studied by mycologists. The research areas covered by Mycoscience extend from such purely scientific fields as systematics, evolution, phylogeny, morphology, ecology, physiology, biochemistry, genetics, and molecular biology, to agricultural, medical, and industrial applications. New and improved applications of well-established mycological techniques and methods are also covered.
