本文报道了第一个完整的迪克斯科线粒体基因组。Dixella sp.线粒体基因组全长15, 574 bp，包含37个基因，包括13个蛋白质编码基因（PCG）、22个转运RNA基因（tRNA）、2个核糖体RNA基因（srRNA和lrRNA）和一个长的控制区。其基因排列与果蝇的祖先基因顺序一致，被认为具有六足动物线粒体基因组的基本模式。大多数PCG以标准ATN密码子开始，而COI使用CCG，ND 1使用TTG，ND 5使用GTG作为起始密码子。所有的PCG终止于共同的终止密码子TAA，除了COII和ND 5以单个胸腺嘧啶终止密码子终止。在srRNA和tRNA（Ile）-tRNA（Gln）-tRNA（Met）（IQM）簇之间有一个703 bp的控制区，没有保守的区段或长串联重复序列。
In the present paper, the first complete mitochondrial genome of the family Dixidae is reported. The complete mitochondrial genome of Dixella sp. is a circular molecule of 15,574bp in length, containing all 37 genes including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (srRNA and lrRNA), and a long control region. Its gene arrangement is conserved with the ancestral gene order of Drosophila yakuba, which is considered to exhibit the ground pattern of Hexapoda mitochondrial genome. Most PCGs start with standard ATN codons, while COI uses CCG, ND1 uses TTG and ND5 uses GTG as start codons. All PCGs terminate in the common stop codons TAA, except for COII and ND5 which end with a single thymine stop codon. There is a 703bp of the control region, located between srRNA and tRNA(lle)-tRNA(Gln)-tRNA(Met) (IQM) cluster, without conserved blocks or long tandem repeats.
