Antarctic icefish is an ideal model for studying cold adaptation mechanisms. The complete mitochondrial genome of was sequenced in this study. The genome sequence is 17 373 bp in length, which comprises 13 protein-coding genes, 22 tRNAs, two rRNAs and a control region. The overall base composition is A: 26.25%, T: 26.05%, G: 17.49% and C: 30.21%, with an A:T content of 52.3%. The phylogenetic analyses based on the concatenated nucleotide sequences of all the genes and control region supported a relatively close relationship with . The complete mitochondrial genome sequence will be useful for evolutionary and functional studies of Antarctic Notothenioids.
南极冰鱼是研究冷适应机制的理想模型。本研究对其完整线粒体基因组进行了测序。基因组序列长度为17373 bp，包括13个蛋白质编码基因、22个tRNA、2个rRNA和一个控制区。总体碱基组成为A：26.25%，T：26.05%，G：17.49%，C：30.21%，A:T含量为52.3%。基于所有基因和控制区的串联核苷酸序列进行的系统发育分析支持其与……有相对密切的关系。完整的线粒体基因组序列将有助于南极南极鱼亚目鱼类的进化和功能研究。
