Abstract

We determined the complete mitochondrial genome (GenBank accession number: KF709435) of the Korean raccoon dog Nyctereutes procyonoides koreensis and compared it with a previously published mitogenome (GenBank accession number: GU256221) of a Chinese raccoon dog. The total length of N. p. koreensis mitogenome is 16,802 bp, with a base composition of 32.1% A, 26.9% T, 26.8% C and 14.2% G. High similarity of 98.7% was found between the complete mitogenome sequences of Korean and Chinese raccoon dogs. Sequence similarity of the two mitogenomes was 99.3% in the other gene regions except for D-loop. The sequence similarity of 99.1% was found in the 13 protein-coding gene regions, whereas 99.6% was identical in mtDNA regions covering all the 22 tRNA genes. There was no variation between 12S rRNAs, whereas 0.5% difference was found between 16S rRNAs.

摘要

我们测定了朝鲜貉Nyctereutes procyonoides koreensis的完整线粒体基因组(GenBank登录号:KF709435),并将其与先前发表的中国貉线粒体基因组(GenBank登录号:GU256221)进行比较。朝鲜貉线粒体基因组全长16,802 bp,碱基组成为32.1% A、26.9% T、26.8% C和14.2% G。朝鲜貉和中国貉的完整线粒体基因组序列之间的相似度高达98.7%。除D环外,两个线粒体基因组在其他基因区域的序列相似度为99.3%。在13个蛋白质编码基因区域的序列相似度为99.1%,而在覆盖所有22个tRNA基因的线粒体DNA区域,序列相似度为99.6%。12S rRNA之间没有差异,而16S rRNA之间存在0.5%的差异。
