    Abstract:
    The complete mitochondrial genome sequence of Danaus chrysippus (Lepidoptera: Nymphalidae: Danainae) was determined. The 15,236 bp long genome encodes 13 putative proteins, two ribosomal RNAs, 22 tRNAs and a non-coding AT-rich region. Its gene arrangement pattern is identical to most of other lepidopteran species. All protein-coding genes start with a typical ATN codon with the exception of COI gene which uses CGA as its initial codon; all PCGs terminate in the common stop TAA or TAG, except COI, COII, ND5 and ND4 which use single T as their stop codons. A total of 102 bp intergenic spacers and a total of 33 bp overlapping sequences are interspersed throughout the whole genome. The mitogenome harbors 22 txRNAs as those of most insect species and all tRNA genes evidence the typical clover leaf secondary structures with the exception of tRNAser (AGN) who loses its dihydrouridine (DHU) arm. The lrRNA and srRNA genes are 1339 and 783 bp, with the AT contents of 84.1 and 84.8%, respectively. The non-coding AT-rich region is 418 bp long, and contains the motif ATAGA followed by a 21-bp poly-T stretch and a microsatellite-like (AT)9 element preceded by the ATTTA motif.
