Abstract

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.
