Abstract

Background: Persicaria amphibia, a member of the Polygonaceae family, exists both aquatic and terrestrial forms. It is native to North America, Asia, Europe, and some parts of Africa.

Objective: This study aimed to determine the genetic diversity within and among populations of P. amphibia and the distribution characteristics of each population to investigate insights into the genetic structure and conservation of P. amphibia.

Methods: In this study, the genetic diversity and structure of 84 P. amphibia individuals from 7 populations in South Korea were analyzed using genotyping-by-sequencing (GBS). We used 2,469 single nucleotide polymorphisms (SNPs) to analyze genetic diversity, principal components, structure, and phylogeny.

Results: Our results showed a mean observed heterozygosity and mean expected heterozygosity of 0.34409 and 0.34082, respectively. Genetic diversity analysis indicated that the variation among populations (60.08%) was greater than that within populations (39.92%). Fixation index values, principal components analysis, structure, and phylogeny analyses showed that the population in Gyodongdo, Ganghwa Island was highly different.

Conclusion: These results provide important insights for better understand the population history and genetic structure of P. amphibia.

利用基因分型测序技术研究韩国蓼科柿树属（Persicaria amphibia）的遗传多样性和结构。

背景介绍柿树是蓼科植物，有水生和陆生两种形态。它原产于北美洲、亚洲、欧洲和非洲的一些地区：本研究旨在确定两栖凤尾竹种群内部和种群之间的遗传多样性以及各种群的分布特征，以深入研究两栖凤尾竹的遗传结构和保护问题：本研究采用基因分型测序法（GBS）分析了来自韩国 7 个种群的 84 个两栖蛙个体的遗传多样性和遗传结构。我们使用了 2469 个单核苷酸多态性（SNPs）来分析遗传多样性、主成分、结构和系统发育：结果表明，平均观察杂合度和平均预期杂合度分别为 0.34409 和 0.34082。遗传多样性分析表明，种群间的变异（60.08%）大于种群内的变异（39.92%）。固定指数值、主成分分析、结构和系统进化分析表明，江华岛行洞岛的种群差异很大：这些结果为更好地了解两栖类的种群历史和遗传结构提供了重要的启示。

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.
