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），是中国境内的极危物种。为支撑遗传学研究、加强野生鱼类资源保护，研究团队利用PacBio与Hi-C测序平台的整合技术，首次构建了花羔红点鲑的染色体水平参考基因组。该基因组组装总长2.52 Gb，重叠群N50（contig N50）为1.29 Mb，且所有重叠群均被锚定至42条染色体上。研究共预测得到45385个蛋白质编码基因，BUSCO完整度达98.8%。该花羔红点鲑染色体水平基因组将成为未来功能基因组学研究的宝贵资源，同时将极大推动该物种的资源探索与保护工作。
