Chromosome-level genome assembly and annotation of the endemic and endangered karst medicinal plant Corydalis saxicola
Corydalis saxicola , an endangered herbaceous plant belonging to the Papaveraceae family and used traditionally as folk medicine, is exclusively endemic to karst habitats. However, the lack of a reference genome limits the implementation of molecular techniques in its breeding, pharmacology and domestication. Here, we present a high-quality chromosome-level genome assembly of C. saxicola based on PacBio HiFi and Hi-C data. The assembled genome size is 240.94 Mb with a contig N50 of 29.21 Mb and BUSCO completeness of 97.71%. Approximately 93.26% of the assembled sequences could be anchored to eight pseudo-chromosomes. A total of 74.29 Mb repeat sequences were identified, which account for 32.33% of the genome. In addition, 24,203 protein-coding genes were identified with a BUSCO completeness of 97.89%. This high-quality genome assembly will serve as a valuable resource for understanding the ecology, genetics, and evolution of C. Saxicola and will help towards its cultivation.
