摘要
利用PCR产物克隆测序测定了阿魏蘑、白灵菇与杏鲍菇rDNA内转录间隔区(ITS)的序列,并对所测序列进行分析。结果表明,阿魏蘑、白灵菇和杏鲍菇三者之间具有较近的亲缘关系,白灵菇与杏鲍菇具有非常近的亲缘关系,但阿魏蘑、白灵菇和杏鲍菇为3个不同的种。
The PCR amplified and cloned sequences of rDNA intemal transcribed spacer （ITS） region of Pleurotus ferulae, P. nebrodensis and P. eryngii were analyzed. The results were as follows： the relationship of P. ferulae , P. nebrodensis and P. eryngii were dose, especially between P. nebrodensis and P. eryngii , but P. ferulae, P. nebrodensis and P. eryngii were three different species.
