香菇菌株分子鉴别技术的分辨率比较 张瑞颖  黄晨阳  左雪梅  姜瑞波  王贺祥  张金霞  摘 要:本研究运用酯酶同工酶、RAPD、IGS1和IGS2 4种方法鉴别2个野生香菇菌株和19个栽培香菇菌株,并比较这4种鉴别方法的分辨率,结果表明:16条酯酶同工酶带中有15条具有多态性,将21个供试菌株分成11个类型,分辨率为0.92;10个随机扩增引物共扩增出86个DNA片段,其中95.3%具有多态性,将21个供试菌株分成16个类型,分辨率为0.97;IGS1将21个供试菌株分成7个类型,分辨率为0.81;IGS2将21个供试菌株分成7个类型,分辨率为0.73.这4种鉴别方法中RAPD的分辨率最高,与这4种鉴别方法的综合分析结果相同,因此RAPD可以作为香菇菌株鉴别的可靠依据. 关键词:酯酶同工酶;随机扩增多态性;转录单位间隔区 分类号:Q939.96 文献标识码:A 文章编号:1672-6472(2005)04-0517-0524 DISCRIMINATORY POWER OF MOLECULAR TYPING TECHNIQUES FOR LENTINULA EDODES ZHANG Rui-Ying  HUANG Chen-Yang  ZUO Xue-Mei  JIANG Rui-Bo  WANG He-Xiang  ZHANG Jin-Xia  日赚500 基金项目:北京市科委项目(D0705007040291)和国家科技基础条件平台工作项目(2004DKA30560) 作者单位:张瑞颖(中国农业科学院农业资源与农业区划研究所,北京,100081)       黄晨阳(中国农业科学院农业资源与农业区划研究所,北京,100081)       左雪梅(中国农业科学院农业资源与农业区划研究所,北京,100081)       姜瑞波(中国农业科学院农业资源与农业区划研究所,北京,100081)       王贺祥(中国农业大学生物学院,北京,100094)       张金霞(中国农业科学院农业资源与农业区划研究所,北京,100081)  参考文献: [1]Albee SR, Mueller GM, Kropp BR, 1996.
