Abstract

Sambus kanssuensis Ganglbauer, 1890 (Coleoptera: Buprestidae), distributed in Gansu and Sichuan Provinces of China, is a phytophagous pest that feeds on the toxic plant Buddleja. However, the genomic resources of this beetle remain unknown, which impedes the understanding of its ecological adaptations. Consequently, this study presents a complete, well-assembled, and annotated genome of S. kanssuensis. The assembled results indicate a genome size of 312.42 Mb, comprising 206 scaffolds, with an N50 of 34.04 Mb; 98.68% of the assembly sequences were anchored to 11 chromosomes, including one sex chromosome. The genome contains 12,723 protein-coding genes, of which 11,977 have been annotated. BUSCO analysis revealed that the completeness of the chromosome-level genome is 97.9%. This chromosome-level genome provides valuable data for further investigations into detoxification mechanisms, ecological adaptations, population genetics, and the evolution of Buprestidae.

摘要

甘肃桑天牛（Sambus kanssuensis Ganglbauer，1890年）（鞘翅目：天牛科）分布于中国甘肃省和四川省，是一种以有毒植物醉鱼草为食的植食性害虫。然而，这种甲虫的基因组资源尚不清楚，这阻碍了对其生态适应性的了解。因此，本研究展示了甘肃桑天牛完整、组装良好且经过注释的基因组。组装结果表明，基因组大小为312.42 Mb，由206个支架组成，N50为34.04 Mb；98.68%的组装序列被锚定到11条染色体上，包括一条性染色体。该基因组包含12723个蛋白质编码基因，其中11977个已被注释。BUSCO分析显示，染色体水平基因组的完整性为97.9%。这个染色体水平的基因组为进一步研究解毒机制、生态适应性、群体遗传学和天牛科的进化提供了有价值的数据。
