生于蔷薇科植物上的链格孢属真菌一新种

A new species of Alternaria on the Rosaceae

报道生于蔷薇科植物枇杷Eriobotrya japonica叶片上的链格孢属一新种,对该种结合形态描述及分子系统学分析明晰其分类地位。命名为枇杷链格孢Alternaria eriobotryae。研究标本保藏于贵州大学植物病理学实验室(HGUP)和中国科学院菌物标本馆(HMAS)。

An Alternaria strain isolated from the leaf of Eriobotrya japonica（Rosaceae） was identified by combining morphological characters and phylogenetic analysis based on sequences of the glyceraldehyde-3-phosphate dehydrogenase（gpd） and Alternaria major allergen（Alt a 1） genes. It was identified as Atlernaria eriobotryae sp. nov. The holotype and ex-type culture are deposited in the Herbarium of Department of Plant Pathology, Agricultural College, Guizhou University（HGUP） and the Herbarium Mycologicum Academiae Sinicae, Beijing, China（HMAS）.
