【摘要】 应用RAPD技术对木耳属四个野生菌株进行了DNA指纹图谱分析。综合 10个随机引物的RAPD聚类分析结果表明 ,供试的四个野生菌株与毛木耳 (Auriculariapolytricha)归为一类 ,四个野生菌株间存在一定的遗传差异 ,不是同一菌株。本研究揭示了木耳属四个野生菌株的类源关系及DNA同质性 ,为进一步界定其系统分类地位提供了较为重要的科学依据。更多还原

【Abstract】 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.更多还原
