Chromosome-level genome assembly and annotation of the endangered species Ormosia henryi
Ormosia henryi of the legume family distributes in southern China, Vietnam and Thailand. This species is well-known as a rare and endangered plant, as well as a remarkable ornamental and timber tree. In this study, we present the first high-quality chromosome-level assembly of O. henryi based on HiFi and Hi-C data. The sequencing data were then assembled onto eight pseudo-chromosomes. The total length of genome assembly is 3.065 Gb, with a contig N50 of 110.65 Mb. We annotate 90,019 protein-coding genes in O. henryi genome, and the BUSCO evaluation exhibits a high score of 95.5%. The phylogenetic analysis displays a monophyletic genus Ormosia within the Leguminosae family, and O. henryi positions in an infrageneric clade of the Old World I. In summary, the high-quality genome sequences of O. henryi will facilitate exploration of the economic value of the species and the wild resources conservation, such as molecular breeding and improvement of disease resistance, will also promote future genomic comparative studies across more species within the amphi-Pacific distributed genus Ormosia.
