Spiraea crenata L. is a deciduous shrub distributed across the Eurasian steppe zone. The species is of cultural and horticultural importance and occurs in scattered populations throughout its westernmost range. Currently, there is no genomic information on the tribe of Spiraeeae. Therefore we sequenced and assembled the whole genome of S. crenata using second- and third-generation sequencing and a hybrid assembly approach to expand genomic resources for conservation and support research on this horticulturally important lineage. In addition to the organellar genomes (the plastome and the mitochondrion), we present the first draft genome of the species with an estimated size of 220 Mbp, an N50 value of 7.7 Mbp, and a BUSCO score of 96.0%. Being the first complete genome in tribe Spiraeeae, this may not only be the first step in the genomic study of a rare plant but also a contribution to genomic resources supporting the study of biodiversity and evolutionary history of Rosaceae.
刺梨（Spiraea crenata L.）是一种落叶灌木，分布于欧亚草原带。该物种具有文化和园艺重要性，在其最西端的分布范围内呈分散种群存在。目前，关于蔷薇科绣线菊属（Spiraeeae）还没有基因组信息。因此，我们使用第二代和第三代测序以及混合组装方法对 S. crenata 进行了全基因组测序和组装，以扩大保护基因组资源，并为该具有重要园艺价值的谱系的研究提供支持。除了细胞器基因组（质体基因组和线粒体基因组），我们还呈现了该物种的首个草图基因组，估计大小为 220 Mbp，N50 值为 7.7 Mbp，BUSCO 得分为 96.0%。作为绣线菊属的首个完整基因组，这不仅可能是稀有植物基因组研究的第一步，也是对支持蔷薇科生物多样性和进化历史研究的基因组资源的贡献。
