Abstract

The mangrove clam (Geloina expansa) is widely distributed in Asia, but its phylogenetic relationship to congeners (especially G. erosa) remains unclear. The complete mitochondrial genome of G. expansa was 15,187 bp and contained the typical 37 genes. Most protein-coding genes started with ATN and terminated with TAA or TAG. Some genes exhibited a different order from those in published Geloina mitogenomes, suggesting gene rearrangement. Phylogenetic analysis revealed that G. expansa clustered with one G. erosa mitogenome. Their small genetic distance (0.029) supports conspecificity, whereas another G. erosa individual showed a distance of 0.189, suggesting an unidentified species within Geloina.

红树蛤（Geloina expansa）的完整线粒体DNA基因组（Mousson, 1849）。

红树蛤（Geloina expansa）广泛分布于亚洲，但其与同系物（尤其是红树蛤）的系统发育关系尚不清楚。全线粒体基因组为15187 bp，包含37个典型基因。大多数蛋白质编码基因以ATN开始，以TAA或TAG终止。一些基因表现出与已发表的Geloina有丝分裂基因组不同的顺序，表明基因重排。系统发育分析表明，大叶金丝桃与一个金丝桃有丝分裂基因组聚集在一起。它们的遗传距离较小（0.029），支持同源性，而另一个G. erosa个体的遗传距离为0.189，表明这是一个未确定的种。
