Dasiphora fruticosa (Rosaceae), commonly known as shrubby cinquefoil, is a flowering shrub of high ornamental value yet underutilized in East Asian landscapes. Given its broad elevational distribution range, D. fruticosa serves as an ideal model for studying genetic adaptations and speciation along elevation gradients. Here, we present a high-quality chromosome-scale assembly of D. fruticosa with a genome size of 249.23 Mb and a contig N50 length of 14.01 Mb. The genome sequence contains 32,613 protein-coding genes, of which 30,643 (93.96%) were functionally annotated. Compared to the published D. fruticosa genome sequence, our assembly demonstrates higher completeness and continuity. Furthermore, comparative genomic analyses provide insights into the phylogenetic relationship and high-altitude adaptation of D. fruticosa. Overall, our study offers a valuable genetic resource for both molecular and evolutionary research on shrubby cinquefoil.
茶藨子(茶藨子科),俗称多枝茶藨子,是一种具有较高观赏价值的开花灌木,但在东亚景观中尚未得到充分利用。鉴于其广泛的海拔分布范围,茶藨子是研究沿海拔梯度遗传适应和物种形成的理想模型。在这里,我们提供了一个高质量的茶藨子染色体水平的组装,基因组大小为 249.23 Mb,contig N50 长度为 14.01 Mb。基因组序列包含 32613 个蛋白质编码基因,其中 30643 个(93.96%)具有功能注释。与已发表的茶藨子基因组序列相比,我们的组装具有更高的完整性和连续性。此外,比较基因组分析为茶藨子的系统发育关系和高海拔适应提供了深入了解。总的来说,我们的研究为灌木茶藨子的分子和进化研究提供了有价值的遗传资源。
