Mitochondrial DNA. 2015;26(6):885-6. doi: 10.3109/19401736.2013.861443. Epub 2014 Jan 10.
The complete sequence of the mitochondrial genome of Pleuragramma antarcticum was obtained from the assembled genome data. The complete sequence was determined to be 18,460 bp in length, containing 13 protein coding genes, 22 tRNA genes, 2 rRNA genes, 2 control regions and a repeat. The general order and contents of the genes are identical with those of other fishes. The Antarctic notothenioid-specific translocation of ND6/tRNA(Glu) exists in the mitogenome. Pleuragramma antarcticum is the only pelagic species which dominates Antarctic fish fauna by more than 90%. Thus, the whole mitogenome sequences of P. antarcticum will provide the basis to understand the deep phylogeny of the Antarctic species.
南极冰鱼(Pleuragramma antarcticum)线粒体基因组的完整序列是从组装好的基因组数据中获得的。该完整序列长度为18460 bp,包含13个蛋白质编码基因、22个tRNA基因、2个rRNA基因、2个控制区和一个重复序列。这些基因的总体顺序和内容与其他鱼类相同。在该线粒体基因组中存在南极亚目特有的ND6/tRNA(Glu)易位。南极冰鱼是唯一一种在南极鱼类区系中占比超过90%的远洋物种。因此,南极冰鱼的完整线粒体基因组序列将为理解南极物种的深层系统发育提供基础。
