The complete nucleotide sequence of the mitochondrial genome of Drosophila formosana (Diptera: Drosophilidae)

AbstractDrosophila formosana (Diptera: Drosophilidae) belongs to the Drosophilidae group of Drosophila. The mitochondrial genome sequence of Drosophila formosana is determined in this study. Mitochondrion of D. formosana is a circular DNA molecule of the 16 100 nucleotide pairs (bp) that contains one encoding region including 37 genes and 1 non-coding A + T-rich region. The similarity and typicality have been showed by the structure and organization analysis. All genes are arranged in the circular DNA molecule. In addition to DN5 that use GTG start codon, all other protein-coding genes (PCGs) start with an ATN start codon. Ten protein-coding genes stop with the termination codon TAN, while other protein-coding genes (PCGs) used incomplete termination codon TA– (cox2, nad5, nad1). The A + T-rich region with a length of 1088 bp is located between rrnS and trnI. The mitochondrial genome of D. formosana has been completely sequenced for the first time in this study.
