Abstract

The present study evaluated genetic diversity of Lithuanian populations of Lythrum salicaria in relation to parameters of riparian environment. Growing along Nemunas, Seaside and Lielupė river basins, 15 populations were examined using amplified fragment length polymorphism markers. Molecular data were related to the river basins, type of land use and cover, natural vice versa regulated fragments of the rivers. Population mean genetic diversity parameters were as follows: percentage of polymorphic loci (57.2), expected heterozygosity (0.183), polymorphismc information content (0.218). Mantel test revealed correlation (R2 = 0.0986, p = 0.01) between genetic and geographic distance of populations. Greater genetic diversity within, rather than among populations (ΦPT = 0.213) was observed. According to the Bayesian clustering, studied populations are admixtures of two gene pools. Analysis of molecular variance revealed significant differentiation between populations belonging to distinct river basins, between populations from natural vs. regulated fragments of the rivers.

李种群遗传与环境特征的关系

本研究利用河岸环境参数评价了立陶宛水杨曲(Lythrum salicaria)居群的遗传多样性。利用扩增片段长度多态性标记对生长在Nemunas、Seaside和lielupnik河流域的15个种群进行了检测。分子数据与河流流域、土地利用类型和覆被有关，反之亦然。群体平均遗传多样性参数为:多态性位点百分率(57.2)、期望杂合度(0.183)、多态性信息含量(0.218)。Mantel检验表明，种群遗传距离与地理距离呈正相关(R2 = 0.0986, p = 0.01)。种群内遗传多样性大于种群间遗传多样性(ΦPT = 0.213)。根据贝叶斯聚类，研究群体是两个基因库的混合物。分子变异分析显示，不同流域的种群之间、自然种群与调节种群之间存在显著差异。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
