The complete mitochondrial genome of Argopecten irradians strain Zhongkehong was sequenced and annotated: it is 16,212 bp in length and contains twelve protein-coding genes (atp8 is absent, as in most species in Anisomyaria), two ribosomal RNA genes, and 21 transfer RNA genes (trnS is absent and there are two copies of trnF). The heavy strand has an overall A + T content of 57.3%; GC and AT skews are 0.249 and -0.262, respectively, indicating more Gs and more Ts than Cs and As. Phylogenetic analysis based on Bayesian Inference and Maximum Likelihood of the twelve protein-coding genes shows that A. irradians has close relationships with A. purpuratus and A. ventricosus; this indicated that A. irradians belongs to the Pectinidae family. The Pectinidae was sister to (Ostreidae + Mytilidae). This work provides general information on the evolution of cultured scallops.
中国科学院海洋研究所“中红 1 号”海湾扇贝的线粒体基因组序列测定及分析：基因组全长 16212bp，共包含 12 个蛋白编码基因（与大多数 Anisomyaria 种类一样，atp8 基因缺失）、2 个核糖体 RNA 基因和 21 个转移 RNA 基因（trnS 基因缺失，并且 trnF 基因有两个拷贝）。重链的 A+T 含量整体为 57.3%；GC 含量和 AT 偏斜分别为 0.249 和-0.262，表明 G 和 T 的含量多于 C 和 A。基于贝叶斯推断和最大似然法对 12 个蛋白编码基因的系统发育分析表明，“中红 1 号”海湾扇贝与虾夷扇贝和华贵栉孔扇贝亲缘关系较近；这表明“中红 1 号”海湾扇贝属于扇贝科。扇贝科与（牡蛎科+贻贝科）并列。本研究为养殖扇贝的进化提供了一般性信息。
