应用5.8S rDNA及ITS区序列分析链格孢种级分类APPLICATION OF SEQUENCING OF 5.8S rDNA, ITS1 AND ITS2 ON IDENTIFICATION AND CLASSIFICATION OF ALTERNARIA AT SEPECIES LEVEL

摘要(Abstract):
对9个链格孢小孢子种和3个大孢子种共20个链格孢菌株的5.8S rDNA及其两侧的ITS1区和ITS2区进行了序列分析。聚类分析结果表明形态差异大的种可以明确加以区分,而供试的9个小孢子种之间差异很小,不能根据对所选区段的序列分析加以区分。传统分类上的滨菊链格孢不属于Alternaria, 其分类地位需进一步研究。
