The complete mitochondrial genome of Yang, 1987 was sequenced in this study. The complete mitochondrial genome is a typical double-stranded circular molecule of 16,343 bp (GenBank accession number: MT268963) comprising of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region. The gene order is identical to that of the putative ancestral arrangement of insects and other lacewings. All protein-coding genes initiate with ATN, except use CGA as start codons and terminate with TAG or TAA, expect and use TA- or a single T-- residue as the stop codon. All tRNAs, ranging from 63 to 72 bp, can be folded into typical clover-leaf secondary structure except for , in which the dihydrouridine (DHU) arm did not form a stable stem-loop structure. The control region is 1433 bp long with an A + T content of 91.4%. In the sampled families of Neuroptera, each family showed a monophyletic cluster and Polystoechotidae + Rapismatidae, Hemerobiidae + (Chrysopidae + (Polystoechotidae + Rapismatidae)), are recovered in phylogenetic analyses with high supports.
本研究对1987年的杨氏样本的线粒体全基因组进行了测序。线粒体全基因组是一个典型的双链环状分子,长度为16343bp(GenBank登录号:MT268963),由13个蛋白质编码基因、22个转运RNA基因、2个核糖体RNA基因和一个控制区组成。基因排列顺序与推测的昆虫和其他草蛉祖先排列相同。所有蛋白质编码基因均以ATN起始,除了 使用CGA作为起始密码子,并以TAG或TAA终止,除了 和 使用TA-或单个T--残基作为终止密码子。所有tRNA长度在63至72bp之间,除了 外,均可折叠成典型的三叶草二级结构,其中二氢尿嘧啶(DHU)臂未形成稳定的茎环结构。控制区长1433bp,A+T含量为91.4%。在脉翅目采样的科中,每个科都显示为一个单系类群,在系统发育分析中,多痣蛉科+瘤蛉科、褐蛉科+(草蛉科+(多痣蛉科+瘤蛉科))得到了高度支持。
