来自土壤的木霉属4个中国新记录种

摘要

从我国安徽、山东、湖北、广东、广西、海南、西藏的土壤分离物中发现了木霉属4个中国新记录种:阿帕拉契木霉Trichoderma appalachiense,须木霉7.barbatum,长梗木霉7.longifialidicum和橄榄色木霉7.oliascens.对上述种的形态学特征和培养特性进行了详细的描述和图示,联合rpb2和tef1基因序列分析确定了它们的分类地位,对新记录种与相近种的系统发育关系进行了讨论.%Strains of Trichoderma in soil from Anhui,Shandong,Hubei,Guangdong,Guangxi,Hainan and Tibet were examined.Four species,T.appalachiense,T.barbatum,T.Iongifialidicum and T.olivascens,are new to China.Morphology and culture characteristics are observed,described and illustrated in detail.The phylogenetic positions of them are determined by sequence analyses of the combined rpb2 and tef1.Relationships between the four species and their close relatives are discussed.
