The complete mitochondrial genome of Dixella sp. (Diptera: Nematocera, Dixidae).

In the present paper, the first complete mitochondrial genome of the family Dixidae is reported. The complete mitochondrial genome ofDixellasp. is a circular molecule of 15,574 bp in length, containing all 37 genes including 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes (srRNAandlrRNA), and a long control region. Its gene arrangement is conserved with the ancestral gene order ofDrosophila yakuba, which is considered to exhibit the ground pattern of Hexapoda mitochondrial genome. Most PCGs start with standard ATN codons, whileCOIuses CCG,ND1uses TTG andND5uses GTG as start codons. All PCGs terminate in the common stop codons TAA, except forCOIIandND5which end with a single thymine stop codon. There is a 703 bp of the control region, located betweensrRNAandtRNAlle-tRNAGln-tRNAMet(IQM) cluster, without conserved blocks or long tandem repeats. [ABSTRACT FROM AUTHOR]
