Clinopodium barosmum (C. barosmum), a rare species within the genus Clinopodium of the Lamiaceae family in northwestern Yunnan, is highly valued for its exceptional ecological and medicinal properties. This study presents the successful assembly of the chromosome-level genome of C. barosmum utilizing Nanopore sequencing technology and chromosome conformation capture techniques. The assembled genome spans 518.59 Mb, with a scaffold N50 length of 21.12 Mb. Notably, 99.97% of the genomic data (518.42 Mb) was accurately anchored and assigned to 24 chromosomes. Analysis revealed a high proportion of repetitive sequences, comprising approximately 51.81% of the genome, and identified 41,864 protein-coding genes. Furthermore, a comparative genomic analysis was conducted, establishing a robust foundation and providing valuable reference data for future investigations of C. barosmum.
滇西香薷（Clinopodium barosmum）是唇形科香薷属的一种珍稀植物，分布于云南西北部，因其独特的生态和药用价值而备受关注。本研究利用纳米孔测序技术和染色体构象捕获技术成功组装了滇西香薷的染色体水平基因组。组装后的基因组大小为518.59 Mb，支架N50长度为21.12 Mb。值得注意的是，99.97%的基因组数据（518.42 Mb）被准确锚定到24条染色体上。分析显示，重复序列占基因组的比例较高，约为51.81%，并鉴定出41,864个蛋白质编码基因。此外，还进行了比较基因组分析，为滇西香薷的未来研究奠定了坚实基础并提供了有价值的参考数据。
