The chromosome-level genome assembly and annotation of the Salvelinus malma

<i>Salvelinus malma</i>, belonging to the Salmonidae family, is an a critically endangered species in theChina. To support genetic research and strengthen the protection of wild fish resources, the first chromosome-level reference genome of <i>S. malma</i> generated through integrated technologies from PacBioand Hi-C sequencing platforms. The genome assembly has a total length of 2.52 Gb and a contig N50 of 1.29 Mb, with contigs further assigned to 42 chromosomes. A total of 45,385 protein-coding genes were predicted, showing 98.8% BUSCO completeness. The chromosome-level genome of <i>S. malma</i> will serve as a valuable resource for future functional genomics research, while greatly facilitating its exploration and conservation.

花羔红点鲑（Salvelinus malma）隶属于鲑科（Salmonidae），是中国境内的极度濒危物种。为支撑遗传研究并强化野生鱼类资源保护，研究人员通过整合PacBio与Hi-C测序平台技术，构建了该物种的首个染色体级参考基因组。该基因组组装总长为2.52 Gb，contig N50为1.29 Mb，并将contig序列进一步锚定至42条染色体上。研究共预测得到45,385个蛋白质编码基因，BUSCO完整度达98.8%。该花羔红点鲑的染色体级基因组将成为未来功能基因组学研究的宝贵资源，同时可极大助力相关探索与保护工作。
