Mitochondrial 16S rRNA gene and COⅠ gene fragments were amplified and sequenced from 4 wild populations of Portunus trituberculatus. Respectively, 524bp and 658bp long partial gene fragments of the 16S rRNA gene and the COⅠ gene were obtained. A high percentage of A+T base composition in the two sequences was observed, which was similar to the results of studies on drosophila, shrimp, crab and other invertebrates.

对分别采自辽东湾、莱州湾、海州湾和舟山的三疣梭子蟹4个野生群体的线粒体16S rRNA和COⅠ基因片段进行了扩增和测序，分别得到长度为524bp和658bp的片段。2段序列的碱基组成均显示较高的A+T比例（16S rRNA基因70.8%，COⅠ基因63%），这与果蝇、虾类、蟹类等无脊椎动物的16S rRNA和COⅠ基因片段研究结果相似。
