Here, we report the complete mitochondrial (mt) genome of Qing_6, an improved strain serving silk production and edible insect resource for 50 years in Northeast China. The circular mt genome spans 15,572 bp in length and contains 37 typical coding genes (13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes). Its A + T-rich region is 552 bp in size exhibiting identical sequence with the first modern improved strain Qinghuang_1. Comparison analysis identified only 12 variable sites (5 substitutions and 7 indels) between Qing_6 and Qinghuang_1. The phylogenetic analysis also clustered Qing_6 and Qinghuang_1 together first, which was in line with the breeding history of the two strains.
在此，我们报道了青6的完整线粒体（mt）基因组，青6是一种在中国东北地区用于蚕丝生产和食用昆虫资源已有50年的改良品系。该环状线粒体基因组长度为15,572 bp，包含37个典型编码基因（13个蛋白质编码基因、2个核糖体RNA基因、22个转运RNA基因）。其富含A+T的区域大小为552 bp，与首个现代改良品系青黄1具有相同序列。比较分析发现青6和青黄1之间仅存在12个可变位点（5个替换和7个插入缺失）。系统发育分析也首先将青6和青黄1聚类在一起，这与两个品系的育种历史一致。
