Sinosolenaiaoleivora(双壳类,Unionida,Unionidae),是一种濒临灭绝的可食用贻贝。2022年被农业农村部评选为十大水产种质资源,具有工业发展潜力。使用Illumina,PacBio,Hi-C技术,组装了S.oleivora的高质量染色体水平基因组。组装的S.oleivora基因组跨越2052.29Mb,重叠群N50大小为20.36Mb,支架N50大小为103.57Mb。302个重叠群,占组装基因组总数的98.41%,使用Hi-C支架锚定到19条染色体上。总共注释了1171.78Mb重复序列,并预测了22,971个蛋白质编码基因。与最近的祖先相比,共发现603个扩展基因家族和1767个收缩基因家族。这项研究为保护提供了重要的基因组资源,进化研究,和许多经济特征的遗传改善,如增长表现。
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.
