We compared patterns of intraspecific polymorphism of two markers with contrasting modes of evolution, nuclear ribosomal DNA (rDNA) and mitochondrial DNA (mtDNA), in the lung fluke, diploid and triploid Paragonimus westermani from three geographical regions of Korea. The genetic distances between three populations of Korean diploid and triploid P. westermani showed no significant difference in the nucleotide sequences of the mitochondrial cytochrome c oxidase subunit I (mtCOI) and ribosomaal second internal transcribed spacer (ITS2) genes. A highly resolved strict-consensus tree was obtained that illustrated phylogenetically useful information of the ITS2 and mtCOI sequences from diploid and triploid P. westermani.
我们比较了来自韩国三个地理区域的二倍体和三倍体卫氏并殖吸虫中,具有不同进化模式的两个标记物——核糖体DNA(rDNA)和线粒体DNA(mtDNA)的种内多态性模式。韩国二倍体和三倍体卫氏并殖吸虫三个种群之间的遗传距离,在线粒体细胞色素c氧化酶亚基I(mtCOI)和核糖体第二内部转录间隔区(ITS2)基因的核苷酸序列上没有显著差异。我们获得了一个高度解析的严格一致树,该树展示了二倍体和三倍体卫氏并殖吸虫ITS2和mtCOI序列的系统发育有用信息。
