Mitochondrial DNA A DNA Mapp Seq Anal. 2016 Nov;27(6):4189-4190. doi: 10.3109/19401736.2014.1003907. Epub 2015 Jan 20.
Thunnus alalunga is an excellent food fish and is of great importance in recreational fisheries. In the study, the complete mitochondrial genome (mitogenome) of T. alalunga is sequenced and annotated, which is a circular DNA molecule with 16,527 bp in length. The overall nucleotide base composition of T. alalunga mitogenome is as follows: A, 28.37%; G, 16.69%; T, 25.46%; and C, 29.49%, with the A+T content of 53.83%, showing an obvious anti-G bias. The entire mitogenome encodes 37 genes in all, comprising 13 protein-coding genes (ATP6 and ATP8, COI-III, Cytb, ND1-6 and 4L), 22 transfer RNA genes (tRNAs), and two ribosomal RNA genes (12S and 16S rRNAs). The complete mitochondrial genome sequence of T. alalunga can provide useful information for the studies on molecular systematics, stock evaluation, and conservation genetics of teleost fishes.
长鳍金枪鱼是一种优质食用鱼，在休闲渔业中具有重要意义。在本研究中，对长鳍金枪鱼的完整线粒体基因组（线粒体基因组）进行了测序和注释，其为一个长度为16,527 bp的环状DNA分子。长鳍金枪鱼线粒体基因组的总体核苷酸碱基组成为：A，28.37%；G，16.69%；T，25.46%；C，29.49%，A+T含量为53.83%，呈现明显的抗G偏向性。整个线粒体基因组共编码37个基因，包括13个蛋白质编码基因（ATP6和ATP8、COI-III、Cytb、ND1-6和4L）、22个转移RNA基因（tRNAs）和两个核糖体RNA基因（12S和16S rRNAs）。长鳍金枪鱼的完整线粒体基因组序列可为硬骨鱼类的分子系统学、种群评估和保护遗传学研究提供有用信息。
