Warburgia ugandensis and Saururus chinensis are two of the most important medicinal plants in magnoliids and are widely utilized in traditional Kenya and Chinese medicine, respectively. The absence of higher-quality reference genomes has hindered research on the medicinal compound biosynthesis mechanisms of these plants. We report the chromosome-level genome assemblies of W. ugandensis and S. chinensis, and generated 1.13 Gb and 0.53 Gb genomes from 74 and 27 scaffolds, respectively, using BGI-DIPSEQ, Nanopore, and Hi-C sequencing. The scaffold N50 lengths were 82.97 Mb and 48.53 Mb, and the assemblies were anchored to 14 and 11 chromosomes of W. ugandensis and S. chinensis, respectively. In total, 24,739 and 20,561 genes were annotated, and 98.5% and 98% of the BUSCO genes were fully represented, respectively. The chromosome-level genomes of W. ugandensis and S. chinensis will be valuable resources for understanding the genetics of these medicinal plants, studying the evolution of magnoliids and angiosperms and conserving plant genetic resources.
乌干达紫檀和中华蛇根草是木兰类植物中最重要的药用植物之一，分别在肯尼亚传统医学和中医药中广泛应用。由于缺乏高质量的参考基因组，这些植物的药用化合物生物合成机制的研究受到了阻碍。我们报告了乌干达紫檀和中华蛇根草的染色体水平基因组组装，使用 BGI-DIPSEQ、Nanopore 和 Hi-C 测序，分别从 74 个和 27 个支架中生成了 11.3 亿碱基对和 5.3 亿碱基对的基因组。支架 N50 长度分别为 82.97 兆碱基对和 48.53 兆碱基对，组装分别锚定在乌干达紫檀和中华蛇根草的 14 条和 11 条染色体上。总共注释了 24739 个和 20561 个基因，分别有 98.5%和 98%的 BUSCO 基因完全代表。乌干达紫檀和中华蛇根草的染色体水平基因组将成为理解这些药用植物遗传学、研究木兰类和被子植物进化以及保护植物遗传资源的宝贵资源。
