The 18S rRNA gene from three scallop species (Placopecten magellanicus, Chlamys islandica, Argopecten irradians) and 7 mactrid clam species (Spisula solida, S. subtruncata, S. solidissima, Mactromeris polynyma, Tresus nuttallii, T. capax, Mulinia lateralis) have been fully sequenced. Phylogenetic analyses have supported the scheme of Waller (1991) for the Pectinidae but conflict with current evolutionary concepts and classification within the Mactridae. The Mactridae are shown to have evolved monophyletically. The current subfamilial position of Mactromeris, and the subgenera Spisula and Hemimactra of the genus Spisula, are not supported by this data.
已对三种扇贝物种(大西洋扇贝、冰岛厚壳贻贝、海湾扇贝)和七种帘蛤科蛤蜊物种(坚固薄壳蛤、亚截形薄壳蛤、极坚固薄壳蛤、多节马珂蛤、努氏獭蛤、大型獭蛤、侧偏穆氏蛤)的18S核糖体RNA基因进行了全序列测定。系统发育分析支持了沃勒(1991年)提出的扇贝科分类方案,但与帘蛤科目前的进化概念和分类存在冲突。结果表明,帘蛤科是单系进化的。这些数据不支持马珂蛤目前的亚科地位以及薄壳蛤属的薄壳蛤亚属和半壳蛤亚属。
