Abstract

Two strains, isolated from in Italy and in Vietnam respectively, proved to be members of an undescribed clade within the species complex based on phylogenetic species recognition on ITS, partial RPB2 and EF-1α gene fragments. Macro- and micro-morphological investigations followed with physiological studies done on this new species: can be distinguished by its conidial morphology. Both isolates of were shown to be pathogenic to the monocot when inoculated on roots and induced hollow root symptoms within two weeks in seedlings. In comparison mild disease symptoms were observed by the same strains on seedlings.

摘要

分别从意大利和越南分离出的两个菌株，基于ITS、部分RPB2和EF-1α基因片段的系统发育物种识别，被证明是一个未描述的进化枝中的成员，该进化枝属于物种复合体。随后对这个新物种进行了宏观和微观形态学研究以及生理学研究：可以通过其分生孢子形态来区分。当接种在根部时，两个分离株均对单子叶植物表现出致病性，并在两周内在幼苗中诱导出空心根症状。相比之下，相同菌株在幼苗上观察到轻微的病害症状。
