The complete mitochondrial genome of Ideopsis similis (Lepidoptera: Nymphalidae: Danainae)

Abstract

The complete mitochondrial nucleotide sequence of Ideopsis similis is 15,200 bp in size, containing typical metazoan 37 genes: 13 protein-coding genes (PCGs), 22 tRNA genes, 2 ribosomal RNA genes and 1 non-coding AT-rich region. All the 13 PCGs initiated with ATN, except for COI gene which started by CGA codon. Nine PCGs used the complete termination codon (TAA), whereas the COI, COII, ND4 and ND5 genes ended with single T. The two rRNA genes (rrnL and rrnS) were 1318 bp and 786 bp in size, with their AT contents of 84.7% and 85.7%, respectively. All tRNA genes display typical secondary cloverleaf structures except for trnS1(AGN) which loses DHU arm. The 404 bp long AT-rich region contains several features common to the other lepidopterans, such as the ATAGA motif followed by a 19 bp poly-T stretch, a 9 bp poly-T stretch and some microsatellite-like (AT)n elements.
