Abstract Oxyria digyna is a perennial herb widely distributed across Arctic and Alpine regions, representing one of the oldest extant Arctic plant lineages. Despite its ecological and evolutionary importance, no chromosome-scale reference genome has been published as a research paper to date. Here, we present two high-quality chromosome-level genome assemblies of O. digyna generated using high-fidelity long-read sequencing data and long-read–based chromatin conformation capture sequencing data.

Abstract The genus Vandenboschia exhibits significant diversity, driven by complex hybridization events and varying ploidy levels in the natural habitats of Korea, leads to misidentifications that obscure its true distribution and classification. To address this issue, the present study employed morphological, cytological, and genotype analyses to clarify the taxonomical circumscription and distribution patterns of the Vandenboschia radicans complex in Korea.
