Genetic variation within and among foundation plant species is known to affect arthropod, plant and soil
microbial communities. We hypothesized that the same would be expected for pathogen communitie...

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...
