Chromosome-level genome assembly of the endangered tree species Ormosia henryi Prain
Abstract
Ormosia henryi Prain, belonging to the Fabaceae family, is an endangered tree species with great economic, ornamental, and medicinal potential. The lack of genetic information and high-quality genome assembly hinders in-depth research on this species as well as its conservation and further utilization. Here, we assembled a chromosome-level genome of O. henryi using Pac-Bio HiFi, Hi-C and short read sequencing. The assembled genome size is approximately 2.69 Gb, with a scaffold N50 of 354.08 Mb and a complete BUSCO score of 98.20%. About 99.97% of the assembled sequences could be anchored to eight pseudo-chromosomes, and 69.09% of the assembled genome were repetitive sequences. In total, we predicted 42,260 protein-coding genes, 88.42% of which could be functionally annotated. This genome assembly provides a valuable resource for various applications, including future conservation and utilization, evolutionary studies, and elucidation of pathways involved in key biological traits of O. henryi.
