日本落叶松群体的叶绿体SSR分析Analysis of Genetic Structure in Population of Larix Kaempferi by Chloroplast SSR Markers
叶绿体微卫星 日本落叶松 单倍型 群体遗传结构
2008/1/8
摘要
利用叶绿体微卫星（cpSSR）分子标记对日本国内的7个日本落叶松（Larix kaempferi）群体遗传结构进行了研究。11对cpSSR引物中筛选出的3对多态性引物，共产生10个长度不同片段，在197个样品中组合出现10个不同的单倍型（haplotype）。各群体的单倍型差异较大。cpSSR基因座揭示了日本落叶松的遗传变异：平均等位基因数A=3.33，平均有效等位基因数NE=1.20，基...
