Abstract

Pharyngocirrus Di Domenico, Martínez, Lana & Worsaae, 2014 belongs to the family Saccocirridae Bobretzky, 1872 and comprises 12 species. Of these, Pharynogocirrus uchidai is known as distributed in only East Asia (Korea and Japan). This study reports the first complete mitogenome of the Protodriliformia group as well as Saccocirridae. The mitogenome of P. uchidai was 15,415 bp long and included 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region. Based on the phylogenetic data, it was difficult to assess the phylogenetic position of Saccocirridae because of the low bootstrapping value and lack of mitogenome references of the Protodriliformia group. Nevertheless, this genetic data is important for better understanding of the phylogenetic position of the Protodriliformia group.

摘要

Pharyngocirrus Di Domenico，Martínez，Lana和Worsaae，2014年隶属于Saccocirridae Bobretzky家族，生于1872年，共有12种。其中，Pharynogocirrus uchidai仅在东亚（韩国和日本）分布。这项研究报告了原毛虫病族和鼠科的第一个完整的有丝分裂基因组。内田假单胞菌的有丝分裂基因组长度为15,415 bp，包括13个蛋白质编码基因，两个rRNA基因，22个tRNA基因和一个控制区。基于系统发育数据，由于自举值低且缺乏原生动物群组的有丝分裂基因组参考，因此难以评估球虫的系统发育位置。尽管如此，这些遗传数据对于更好地了解原形目群的系统发育位置很重要。
