| Abstract: | We determined the nucleotide sequence of the mitochondrial genome (mtgenome) of Spilonota lechriaspis Meyrick (Lepidoptera: Tortricidae). The entire closed circular molecule is 15,368 bp and contains 37 genes with the typical
gene complement and order for lepidopteran mtgenomes. All tRNAs except tRNASer(AGN) can be folded into the typical cloverleaf secondary structures. The protein-coding genes (PCGs) have typical mitochondrial
start codons, with the exception of COI, which uses the unusual CGA one as is found in all other Lepidoptera sequenced to
date. In addition, six of 13 PCGs harbor the incomplete termination codons, a single T. The A + T-rich region contains some
conserved structures that are similar to those found in other lepidopteran mtgenomes, including a structure combining the
motif ‘ATAGA’, a 19-bp poly(T) stretch and three microsatellite (AT)n elements which are part of larger 122+ bp macrorepeats. This is the first report of macrorepeats in a lepidopteran mtgenome. |
