Abstract

Sclerotinia borealis is among the most psychrophilic snow mold pathogen, mainly attacking Poaceae crops such as winter wheat and forage grasses as well as non-Poaceae plants under snow. Isolates were collected through the extensive surveys from North Atlantic islands through European and Asian Russia to Japan. Morphological characterization as well as the effects of temperature and water potential on mycelial growth defined three varieties, i.e., vars. borealis, subarctica, and okhotskana. Phylogenetic analyses based on ITS and EF1-α regions of genomic DNA indicated the monophyly of S. borealis and supported varietal differentiation.

北核菌及其变种，亚北极11月变种和11月变种okhotskana。

北方菌核菌（Sclerotinia borealis）是最嗜冷的雪霉菌病原菌之一，主要侵染禾本科作物如冬小麦和牧草，也侵染雪下的非禾本科植物。通过从北大西洋岛屿到欧洲和亚洲俄罗斯到日本的广泛调查收集了分离株。形态表征以及温度和水势对菌丝生长的影响定义了三个品种，即vars。北方、亚北极和鄂霍茨卡那。基于ITS和EF1-α区基因组DNA的系统发育分析表明，北方稻属植物具有单系性，支持品种分化。

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.
