title: The complete mitochondrial genome of Bombyx mori strain Yu5 (Lepidoptera: Bombycidae).
abstract: The complete mitochondrial genome of Bombyx mori strain Yu5 (Lepidoptera: Bombycidae) is a circular molecule of 15,644  bp in length, containing 37 typical coding genes and one non-coding AT-rich region. The overall composition of the mitogenome was A (43.07%), G (7.34%), C (11.33%), and T (38.26%). Its gene order and content were identical to the common type found in most insect mitogenomes. All protein coding genes (PCGs) started with a typical ATN initiation codon, except for the cox1 gene, which began with CGA codon. Eleven genes used standard complete termination codon TAA, whereas the cox1 and cox2 genes ended with single T. All tRNA genes displayed typical secondary cloverleaf structures as those of other insects. Additionally, the 494  bp long AT-rich region contained several structures common to the other lepidopterons, such as some structures of repeated motifs and microsatellite-like elements and a poly-A element upstream of transfer RNA M (trnM) gene.
