竹类煤烟病大型病原菌——海绵胶煤炱菌的分子鉴定

Molecular identification of Scorias spongiosa of a large pathogen of the bamboo sooty molds

煤烟病是竹类常见的一类病害。在四川省成都、德阳、绵阳、宜宾和江苏、浙江等地共采集到100多份竹类煤烟病的一种产生大型子实体的病原菌标本,经组织、孢子分离得到纯培养菌株。提取纯培养子实体的总DNA,进行ITS序列分析,鉴定为Scorias spongiosa,海绵胶煤炱菌。该菌是中国竹类病原菌的新记录种。

Sooty molds is a disease common type of bamboo.The number of specimens of the bamboo sooty molds were collected more than 100 from Chengdu,Deyang,Mianyang,Yibin of Sichuan Province,Zhejiang and Jiangsu Province.It was discovered that the bamboo sooty molds produced large fruiting bodies,and pure strains were obtained by tissue and spores isolation method.The total DNA of the pure culture fruiting bodies were extracted for ITS sequence analysis,and the molds were identified as Scorias spongiosa,a new record species of bamboo pathogenic fungus in China.
