The complete mitochondrial genome of a balanced sex-linked lethal silkworm and its phylogenetic analysis

Abstract

Male-only rearing has long been desirable in sericulture because males have superior economic characteristics. To this end, a balanced sex-linked lethal (BSL) system has been developed. Here, we report the first complete mitochondrial genome of the BSL silkworm (Bombyx mori). Phylogenetic analysis revealed that the BSL silkworm is more closely related to Japanese B. mori than Chinese B. mori. The new mitochondrial genome provides valuable information to further explore genetic diversity and origin of this species.
