摘要:以蛇足石杉为材料,经过严格的表面消毒,分离纯化得到1株内生真菌JSM 10.对JSM 10进行培养特征、显微形态观察和基于ITS序列的系统发育分析.结果表明:菌株JSM 10和Fusarium属的 Fusarium oxysporum菌株系统发育关系最为密切,聚在同一个小枝上,相似程度为99%.因此,从系统发育分析来看,JSM 10应为Fusarium oxysporum菌株.

关键词: 蛇足石杉, 内生真菌, ITS序列, 系统发育分析, 鉴定

Abstract: Endophytic fungi JSM 10 was isolated from surface-sterilized Huperzia crispate.Phylogenetic analysis of JSM 10 was carried out based on ITS gene sequences.Phylogenetic analysis result showed that JSM 10 strain was closely related to the recognized members of the genus Fusarium,in which strain JSM 10 resembled Fusarium oxysporum at a rate of 99% and JSM 10 was identified as Fusarium oxysporum.

Key words: Huperzia crispate, endophytic fungi, ITS gene sequence, phylogenetic analysis, identification
