The number of high-quality genomes is rapidly increasing across taxa. However, it remains limited for coral reef fish of the Pomacentrid family, with most research focused on anemonefish. Here, we present the first assembly for a Pomacentrid of the genus . Using PacBio long-read sequencing with 94.5× coverage, the genome of the Sapphire Devil, , was assembled and annotated. The final assembly comprises 896 Mb pairs across 91 contigs, with a BUSCO completeness of 97.6%, and 28,173 genes. Comparative analyses with chromosome-scale assemblies of related species identified contig-chromosome correspondences. This genome will be useful as a comparison to study specific adaptations linked to the symbiotic life of closely related anemonefish. Furthermore, is found in most tropical coastal areas of the Indo-West Pacific and could become a model for environmental monitoring. This work will expand coral reef research efforts, highlighting the power of long-read assemblies to retrieve high quality genomes.
跨分类群的高质量基因组数量正在迅速增加。然而,雀鲷科珊瑚礁鱼类的高质量基因组数量仍然有限,大多数研究集中在海葵鱼上。在这里,我们展示了雀鲷属鱼类的首个基因组组装。利用PacBio长读长测序技术,测序深度达94.5倍,对蓝魔雀鲷(Chrysiptera cyanea)的基因组进行了组装和注释。最终组装结果包含91个重叠群,共896 Mb对,BUSCO完整性为97.6%,含有28173个基因。与相关物种的染色体水平组装进行比较分析,确定了重叠群与染色体的对应关系。该基因组将有助于研究与近亲海葵鱼共生生活相关的特定适应性。此外,蓝魔雀鲷分布于印度-西太平洋的大多数热带沿海地区,有望成为环境监测的模型。这项工作将扩大珊瑚礁研究的范围,凸显长读长组装技术在获取高质量基因组方面的强大作用。
