河南省烟草疫霉遗传多样性与遗传结构的RAPD分析
烟草疫霉 随机扩增多态性DNA 遗传多样性 遗传结构
2021/4/7
为了明确河南省烟草疫霉群体的遗传多样性与遗传结构，利用RAPD分子标记对河南省的34个烟草疫霉菌株进行分析。结果表明，6条RAPD引物共扩增出30个条带，多态性条带比率为90%；Nei’s基因多样性指数为0.271 0，Shannon信息指数为0.402 8；菌株间的遗传相似系数在0.59~1.00，相似系数0.80水平下UPGMA聚类可将34个菌株划分为6个类群，类群Ⅰ包括26个菌株，为优势类群...

运用RAPD技术对云南省魔芋软腐病菌系进行类群划分的初步研究
魔芋 软腐病 遗传多样性 RAPD
2008/5/28
引起魔芋发生病害的病菌有很多种,其中软腐病是对云南魔芋生产和产量影响最为严重的病害。本试验运用RAPD技术对从云南省部分地区采集并分离得到的26个病菌进行遗传多样性的分析,从而对所分离得到的病菌进行病菌类群的初步划分。用已筛选出的7条引物对26个菌进行RAPD扩增后,发现7条随机引物共得到64条电泳带。在71.8%的相似水平上,将其分成3个类群：a,b和c。c组是SM-2（嵩明）;b组为HZ-2(...
