Craigia yunnanensis, endemic to East Asia, is an endangered species with important economic and scientific research values. However, the absence of a reference genome has hindered studies on genetic variation and conservation management of C. yunnanensis. To address this gap, we present a high-quality chromosome-level genome sequence of C. yunnanensis by using PacBio HiFi sequencing and Hi-C scaffolding. The genome has a total length of 1,618.96 Mb with scaffold N50 of 39.39 Mb and 98.00% of the genome assigned to 41 chromosomes. BUSCO assessment yielded a completeness score of 99.40%. Furthermore, we predicted 58,969 proteincoding genes, and 94.09% of them was functionally annotated. Assembly of the C. yunnanensis genome facilitates a deeper understanding of adaptive evolution in Craigia, knowledge that is fundamental to promoting the conservation and enabling evidence-based management of this endangered plant.
