This study reports the first complete mitochondrial genome of Guérin-Méneville 1855 (Lepidoptera: Saturniidae) strain Dingzhou_1, a silkworm resource serving silk production in North Korea. The mitochondrial genome is circular with 15,573 bp in length encoding 37 typical mitochondrial genes (13 protein-coding genes, two ribosomal genes, and 22 transfer genes). The 553-bp A + T-rich region harbors a repeat region composed of 6 ∼ 38 bp tandem repeat units, as found in other known inbred strains from Chinese populations. The phylogenetic analysis clustered Dingzhou_1 from North Korea together with Chinese Liaoning population, suggesting that oak silkworm in North Korea might be introduced from her neighbor China Liaoning.
本研究报道了朝鲜用于丝绸生产的家蚕资源——1855年格氏大蚕蛾（鳞翅目：大蚕蛾科）定州1号品系的首个完整线粒体基因组。该线粒体基因组呈环状，长度为15573 bp，编码37个典型的线粒体基因（13个蛋白质编码基因、2个核糖体基因和22个转移基因）。富含A+T的553 bp区域含有一个由6至38 bp串联重复单元组成的重复区域，这与中国种群中其他已知的近交系相同。系统发育分析将来自朝鲜的定州1号与中国辽宁种群聚类在一起，表明朝鲜的柞蚕可能是从邻国中国辽宁引入的。
