【中文摘要】 應(yīng)用RAPD技術(shù)對木耳屬四個野生菌株進行了DNA指紋圖譜分析。綜合 10個隨機引物的RAPD聚類分析結(jié)果表明 ,供試的四個野生菌株與毛木耳 (Auriculariapolytricha)歸為一類 ,四個野生菌株間存在一定的遺傳差異 ,不是同一菌株。本研究揭示了木耳屬四個野生菌株的類源關(guān)系及DNA同質(zhì)性 ,為進一步界定其系統(tǒng)分類地位提供了較為重要的科學依據(jù)。

【英文摘要】 DNA fingerprints of four wild strains of Auricularia were analyzed by RAPD technique. These four wild strains were grouped into Auricularia polytricha based on the result of RAPD cluster analysis with ten random primers. But they were four distinct strains because there were certain genetic differences among them. The result revealed the phylogenetic relationship and the DNA homogeneity among these four wild strains of Auricularia. And it also provided more important scientific basis for delimiting their taxonomic position.
