Chromosome-level and haplotype-resolved assembly of Bougainvillea glabra. Bougainvillea glabra

Bougainvillea. glabra Choisy, a common perennial shrub or climbing vine in tropical and subtropical areas, has significant ornamental and ecological value due to its immensely showy, floriferous blooms and multiple stresses adaptability. In this study, based on PacBio and Hi-C sequencing data, we presented the haplotype-resolved, and chromosome-level assembled genomes for B. glabra (2n=34). We totally get two haplotypes with genome size from 2,855,692,602 to 2,889,511,499 bp, N50 of 165~167 Mbp, and both anchored to 17 pseudochromosomes with anchor ratio of 97.07% and 97.55% respectively. Through the BUSCO evaluation process, the two assembled haplotypes both exhibited the high score of 96%. By combining the high-confidence different evidence of genome structure annotation pipeline we annotated each haplotype containing ~33,000 predicted genes, of which 86% were functionally annotated by different databases. These high-quality haplotypes assembly and annotation results will serve as a great genomic resource to explore the ornamental traits and environmental adaptability and accelerate improvement in future.
