Mitochondrial DNA. 2015;26(6):887-8. doi: 10.3109/19401736.2013.861444. Epub 2014 Jan 10.
The complete sequence of the mitochondrial genome of the Antarctic icefish Chaenocephalus aceratus was determined to be 17311 bp in length, and to contain 13 protein coding genes (PCGs), 22 tRNA genes and 2 rRNA genes. The total A+T content is 52.8%. The notothenioid-exclusive ND6/tRNAGlu translocation was observed in the mitogenome of C. aceratus. Generally, the order and contents of the other genes are identical with those of other fishes. Antarctic icefishes, the only vertebrates which do not have hemoglobins, have evolved to survive sub-freezing temperature. Therefore, the whole mitogenome sequences of C. aceratus will provide the insights into resolving the evolutionary history of icefish.
南极冰鱼（Chaenocephalus aceratus）线粒体基因组的完整序列长度为17311 bp，包含13个蛋白质编码基因（PCGs）、22个tRNA基因和2个rRNA基因。A+T总含量为52.8%。在南极冰鱼的线粒体基因组中观察到了南极鱼亚目特有的ND6/tRNAGlu易位。一般来说，其他基因的顺序和内容与其他鱼类相同。南极冰鱼是唯一没有血红蛋白的脊椎动物，它们已经进化到能够在亚冰点温度下生存。因此，南极冰鱼的完整线粒体基因组序列将为解析冰鱼的进化历史提供见解。
