Oxalis articulata is a widely distributed perennial herb known for its adaptability to diverse environmental conditions. Here, we report the first haplotype-resolved, chromosome-scale genome assembly for O. articulata (Oxalidaceae), generated through PacBio HiFi long reads and Hi-C technology. The resulting assembly comprises two haplotypes with sizes of 377.04 Mb (contig N50 = 31.13 Mb) and 342.70 Mb (contig N50 = 47.46 Mb), respectively. We predicted 36,063 protein-coding genes (94.33% functionally annotated) and 38,292 protein-coding genes (93.80% functionally annotated) in the two haplotypes, respectively. This high-quality genome assembly lays a solid groundwork for future initiatives in ecological and biochemical research for O. articulata.
关节酢浆草是一种广泛分布的多年生草本植物，以其对多种环境条件的适应性而闻名。在此，我们报告了通过PacBio HiFi长读长和Hi-C技术生成的首个关节酢浆草（酢浆草科）单倍型解析的染色体水平基因组组装。所得组装分别包含两个单倍型，大小分别为377.04 Mb（重叠群N50 = 31.13 Mb）和342.70 Mb（重叠群N50 = 47.46 Mb）。我们在这两个单倍型中分别预测了36,063个蛋白质编码基因（94.33%具有功能注释）和38,292个蛋白质编码基因（93.80%具有功能注释）。这种高质量的基因组组装为关节酢浆草未来的生态和生化研究奠定了坚实基础。
