Sinosolenaia oleivora (Bivalve, Unionida, Unionidae), is a near-endangered edible mussel. In 2022, it was selected by the Ministry of Agriculture and Rural Affairs as a top-ten aquatic germplasm resource, with potential for industrial development. Using Illumina, PacBio, and Hi-C technology, a high-quality chromosome-level genome of S. oleivora was assembled. The assembled S. oleivora genome spanned 2052.29 Mb with a contig N50 size of 20.36 Mb and a scaffold N50 size of 103.57 Mb. The 302 contigs, accounting for 98.41% of the total assembled genome, were anchored into 19 chromosomes using Hi-C scaffolding. A total of 1171.78 Mb repeat sequences were annotated and 22,971 protein-coding genes were predicted. Compared with the nearest ancestor, a total of 603 expanded and 1767 contracted gene families were found. This study provides important genomic resources for conservation, evolutionary research, and genetic improvements of many economic traits like growth performance.
橄榄蛏蚌（双壳纲、珠蚌目、珠蚌科）是一种濒危可食用贻贝。2022 年，它被农业农村部选为十大水生物种资源之一，具有发展潜力。利用 Illumina、PacBio 和 Hi-C 技术，组装了橄榄蛏蚌的高质量染色体水平基因组。组装的橄榄蛏蚌基因组跨度为 2052.29 Mb，contig N50 大小为 20.36 Mb，scaffold N50 大小为 103.57 Mb。302 个 contigs 占总组装基因组的 98.41%，使用 Hi-C 支架将其锚定到 19 条染色体上。共注释了 1171.78 Mb 的重复序列，并预测了 22971 个蛋白质编码基因。与最近的祖先相比，共发现 603 个扩展和 1767 个收缩基因家族。这项研究为保护、进化研究以及生长性能等许多经济性状的遗传改良提供了重要的基因组资源。
