This is the first report of a transcriptome assembly of a newly discovered hydrothermal vent mussel, Gigantidas vrijenhoeki (Bivalvia: Mytilidae), on the Central Indian Ridge. Gigantidas vrijenhoeki was identified from material collected at the newly discovered Onnuri Vent Field (OVF) on the Central Indian Ridge in 2018, and was reported as a new species, distinct from another dominant hydrothermal vent mussel, Bathymodiolus marisindicus, in 2020. We sequenced the transcriptome of G. vrijenhoeki using the Illumina HiSeq X System. De novo assembly and analysis of the coding regions predicted 25,405 genes, 84.76% of which was annotated by public databases. The transcriptome of G. vrijenhoeki will be a valuable resource in studying the ecological and biological characteristics of this new species, which is distinct from other deep-sea mussels. These data should also support the investigation of the relationship between the environmental conditions of hydrothermal vents and the unique distribution of G. vrijenhoeki in the OVF of the Central Indian Ridge.

这是关于印度中部海脊新发现的热液喷口贻贝Gigantidas vrijenhoeki（双壳类：贻贝科）的转录组组装的第一份报告。Gigantidas vrijenhoeki是从 2018 年在印度中部新发现的 Onnuri Vent Field (OVF) 收集的材料中鉴定出来的，并于 2020 年被报告为一个新物种，与另一种主要的热液喷口贻贝Bathymodiolus marisindicus 不同。我们对使用 Illumina HiSeq X 系统的G. vrijenhoeki转录组。编码区的从头组装和分析预测了 25,405 个基因，其中 84.76% 被公共数据库注释。G. vrijenhoeki的转录组将成为研究这一新物种的生态和生物学特征的宝贵资源，这种新物种不同于其他深海贻贝。这些数据还应支持对热液喷口的环境条件与印度洋中脊 OVF 中G. vrijenhoeki独特分布之间关系的调查。
