摘要

毛蕨属大约有200种，其中分类细分是困难的，但可能的。由于其蓬松的白色花序和小的微型花和喙状的种子，它是该地区最突出的毛蕨属物种之一。我们没有关于这个物种在伊朗的种群遗传结构的数据。因此，通过对该分类群的遗传和形态变异进行了种群遗传和形态调查。采用SCoT分子标记进行群体遗传调查。遗传多样性分析表明，各居群间存在中等程度的遗传变异，而PCoA居群间存在一定程度的遗传混杂。AMOVA在人群间产生了显著的遗传差异。形态计量学分析表明，所研究群体之间存在高度重叠。结果表明，SCoT标记具有良好的鉴别能力，能够区分研究人群。该标记可用于评价岷江花居群的遗传多样性和基因型鉴定。

Population genetic study in Epilobium minutiflorum (Onagraceae) in Iran

The genus Epilobium has about 200 species in which taxonomic subdivisions are difficult but possible. Species E. minutiflorum due to its fluffy white inflorescence and small miniature flowers and beaked seeds, it is one of the most prominent species of the genus Epilobium in the region. We have no data on the population genetic structure of this species in the Iran. Therefore a population genetic and morphological investigation was performed through light on genetic and morphological variability in this taxa. We used SCoT molecular markers for population genetic investigation. Genetic diversity analyses revealed a moderate genetic variability between E. minutiflorum populations, while PCoA showed some degree of genetic admixture among populations. AMOVA produced significant genetic difference among populations. Morphometric analysis showed that high degree of overlap among the studied populations. However, the results showed that SCoT marker has a good discrimination power and can differentiate the studied populations. This marker can be used to evaluate genetic diversity and identify genotypes of E. minutiflorum populations.
