Berchemiella wilsonii Genome sequencing and assembly

Berchemiella wilsonii (Schneid.) Nakai is one of the National Key Protected Wild Plants in China, and one of the 120 Plant Species with Extremely Small Populations in China. By combining PacBio HiFi sequencing, DNBSEQ sequencing and Hi-C sequencing, we have assembled a chromosome-scale,haplotype-resolved genome for B. wilsonii. The final assembled haplotype A and haplotype B genomes were 216.84Mb and 217.69Mb, anchored to 2n=24 chromosomes, with contig N50 lengths of 18.24 Mb and 18.03 Mb, respectively. Further, BUSCO analysis showed an extremely high assembly completeness (98.9% complete BUSCO genes). The genome contains a total of 22,828 coding genes, of which 21,992 (96.34%) were functionally annotated. This is the first report of the genome of B. wilsonii and the high-quality genome will provide valuable genomic resource for endangered plant species conservation .
