The complete mitochondrial genome of the wild silkworm Bombyx mandarina strain Shenyang

Abstract

Here, we report the complete mitochondrial genome of Bombyx mandarina strain Shenyang. The genome is 15,682 bp in length and contains a typically conserved 37 metazoan genes (13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and an A + T-rich region). The A + T-rich region of B. mandarina Shenyang contains only one copy of the repeat element of a 126-bp as found in Chinese B. mandarina. A phylogenetic analysis provides a solid evidence that B. mandarina Shenyang belongs to Chinese B. mandarina, rather than Japanese B. mamdarina. The mitochondrial genome will provide useful information for the origin of the present day silkworm.
