Abstract
The complete mitochondrial genome of Bombyx mori strain Baiyun (Lepidoptera: Bombycidae) was determined in this study. The genome was 15,629 bp long with 37 typical animal mitochondrial genes and 1 non-coding A + T-rich region. Its gene content and order were identical to those of other lepidopteran mitochondrial genomes. All protein-coding genes (PCGs) were initiated by ATN codons except for the COI gene, which began with CGA codon. Eleven PCGs stopped with termination codon TAA, whereas the COI and COII genes ended with single T. All the tRNA genes showed typical secondary cloverleaf structures. The 496 bp AT-rich region contains several features common to other lepidopterans, such as the motif ATAGA followed by an 18-bp poly-T stretch and two microsatellite-like (TA)8 and (AT)9 elements preceded by the ATTTA motif.
