【摘要】 采用组织分离的方法从野生硫磺菌(Laetiporus sulphureus)子实体上分离得到菌株ts,以其基因组为模板扩增获得该菌株的ITS序列,序列分析结果表明:该菌株与GenBank中Laetiporus sulphureus var.sulphureus的3个日本分离株聚为一簇,ITS核苷酸一致率为98.31%～99.25%,而与其它22个来自不同国家的硫磺菌属菌株的ITS核苷酸一致率为91.93%～98.12%,依此结果,ts菌株应为L.sulphureus var.sulphureus。

【Abstract】 Fungal mycelium,isolated from a fruit body of Laetiporus sulphureus growing in the wild on a species of Quercus located on Tai Mountain,was identified as a strain(designated strain ts) of L.sulphureus var.sulphureus based on ITS sequencing.The ITS sequence(deposited in GenBank under the accession number,JF946748) was used along with ITS sequences from other Laetiporus species to construct a phylogenetic tree using the neighbor-joining method.This revealed a high genetic similarity(98.31%-99.25%)...
