In this study, the complete mitochondrial genome of was assembled through next-generation sequencing data. This circular mitochondrial genome of is 16,947 bp in length and has a base composition of A (30.8%), T (24.7%), C (29.9%), and G (14.5%), demonstrating a bias of higher AT content (55.5%) than GC content (44.5%). The mitochondrial genome contains a typically conserved structure among bird mitogenomes, encoding 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), two ribosomal RNA genes (12S rRNA and 16S rRNA), and a control region (D-loop region). Except ND6, all other PCGs were located on the H-strand. ATP8 gene and ATP6 gene were overlapped by 8 bp. The whole mt genome of and other Corvoidea mitogenomes (24 species, in total) were used for phylogenetic analysis. The result indicated has the closest relationship with (NC_024698) and clustered within clade of genus .
在本研究中，通过下一代测序数据组装了[物种名称]的完整线粒体基因组。该[物种名称]的环状线粒体基因组长度为16,947 bp，碱基组成为A（30.8%）、T（24.7%）、C（29.9%）和G（14.5%），显示出AT含量（55.5%）高于GC含量（44.5%）的偏向性。线粒体基因组包含鸟类线粒体基因组中典型的保守结构，编码13个蛋白质编码基因（PCGs）、22个转运RNA基因（tRNA）、两个核糖体RNA基因（12S rRNA和16S rRNA）以及一个控制区（D-loop区）。除ND6外，所有其他PCGs都位于H链上。ATP8基因和ATP6基因重叠8 bp。[物种名称]的整个线粒体基因组和其他鸦总科线粒体基因组（共24个物种）用于系统发育分析。结果表明，[物种名称]与[参考物种名称]（NC_024698）关系最密切，并聚类在[属名]属的分支内。
