摘要
从中国青岛沿岸潮间带采集9种海藻,包括3种褐藻、4种绿藻和2种红藻,通过传统培养方法共分离获得92株真菌。根据形态学特征和真菌转录间隔区(ITS)r DNA序列分析对所得菌株进行鉴定,结果显示:92株真菌隶属子囊菌门56种,担子菌门1种及接合菌门1种;优势属为枝顶孢属、曲霉属、枝孢属、青霉属和帚霉属;无性型真菌40种,占总菌株数量的75%;绿藻门刺松藻的真菌多样性最高,其次为褐藻门鼠尾藻,红藻门珊瑚藻的真菌多样性最低。本研究首次对中国沿岸潮间带海藻中的真菌多样性进行报道,为进一步研究藻生真菌生态功能提供参考。
Fungal diversity associated with nine species of marine macroalgae,including three brown algae,four green algae and two red algae from Qingdao coast of China were investigated using cultured-dependent method.A total of 92 fungal strains were isolated from 34 asymptomatic algal thalli.On the basis of morphological characteristics and internal transcribed spacer（ITS）r DNA sequences analysis,they were identified and assigned to 56 species of Ascomycota,one species of Basidiomycota and one species of Zygomycota.The dominant genera were Acremonium,Aspergillus,Cladosporium,Penicillium and Scopulariopsis.Anamorphic fungi were represented by 40 species,accounting for 75%of the total isolates.The highest fungal diversity was uncovered from the green alga Codium fragile,followed by the brown alga Sargassum thunbergii,and the lowest was observed from the red alga Corallina officinalis.This is the first report of the fungal diversity associated with marine algae from Chinese coastal regions,and will contribute to further insight into the understanding of the functions of algicolous fungi.
