Abstract

Caddisflies of Stenopsyche angustata (Trichoptera, Stenopsychidae) are widely distributed in various freshwater bodies and a few species inhabit marine environments. The mitochondrial genome was sequenced by Illumina high-throughput sequencing, and then the complete mitochondrial genome sequence was obtained through splicing and assembly. The mitochondrial genome sequence size was 15,371 bp, comprising 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a control region. Two of the protein-coding genes (COX 2 and nad 5) had an incomplete termination codon T. In addition, the start codon of all protein-coding genes was ATN, except for the start codon of the nad4l gene which was GTG. The base composition of the mitochondrial genome was 41.64% A, 35.03% T, 7.81% G, and 15.52% C.

摘要

食肉夜蛾（Snonopsyche angustata）（食翅目，Stenopsychidae）的象鼻虫广泛分布在各种淡水体中，少数物种栖息在海洋环境中。通过Illumina高通量测序对线粒体基因组进行测序，然后通过剪接和组装获得完整的线粒体基因组序列。线粒体基因组序列大小为15371 bp，包含13个蛋白质编码基因，22个tRNA基因，两个rRNA基因和一个控制区。两个蛋白质编码基因（COX 2和nad 5）的终止密码子T不完整。此外，除nad4l的起始密码子外，所有蛋白质编码基因的起始密码子均为ATN。基因是GTG。线粒体基因组的碱基组成为41.64％A，35.03％T，7.81％G和15.52％C.
