摘要:
采用表型性状和序列相关扩增多态性(简称SRAP)分子标记对香茶菜(Isodon japonica)不同海拔居群的遗传多样性进行分析。结果表明:(1)香茶菜8个叶表型性状在居群间和居群内均存在显著或极显著差异,说明不同居群叶表型性状存在明显的变异;(2)香茶菜叶柄性状的平均变异系数(CV,19.707%)>叶片性状的平均变异系数(CV,9.905%),叶柄性状稳定性较低;(3)居群间平均表型分化系数(VST,69.89%)>居群内平均表型分化系数(VST,30.11%),居群间变异是其主要的变异来源;(4)非加权组平均法(简称UPGMA)聚类分析显示,8个香茶菜居群分为三大类;(5)香茶菜居群具有较高的遗传多样性,平均多态位点数(NPL)、平均多态位点百分率(PPB)、平均Shannon多样性指数(I)分别为60.875、82.083%、0.387;(6)8个居群遗传多样性变化规律随海拔的升高先增加后降低;(7)分子生物学方差分析(简称AMOVA)显示,居群间遗传变异占总变异的75%,与表型性状分析的主要变异来源一致;(8)聚类分析将8个居群分为3类,海拔相近的居群优先聚类。
