The chromosome-scale genome assembly, annotation of Bischofia polycarpa (H. Lév.) Airy Shaw, Phyllanthaceae

Bischofia polycarpa (2n = 68), belonging to Phyllanthaceae family, is a native deciduous tree with naturally distribution ranging from southern Qinling Mountains and Huaihe River basin to the northern regions of Fujian and Guangdong, China. It holds significant horticultural, ornamental, and medicinal value and serves as a crucial winter food resource for wild birds. Herein, we report a de novo genome assembly for B. polycarpa, utilizing a combination of PacBio HiFi Reads and Hi-C data. In total, the genome size reaches 585.68 Mb with a contig N50 of 12.62 Mb, and 99.06% (580.18 Mb) of the assembly successfully anchored on 34 chromosomes. The genome comprises approximately 62.77% repetitive sequences and 32,554 protein-coding genes, of which 96.15% could be functionally annotated. The BUSCO analysis reveals a genome completeness of 95.42% (n = 1,540), including 1,499 (92.87%) single-copy BUSCOs and 41 (2.54%) duplicated BUSCOs. This high-quality genome of the Phyllanthaceae enriches our understanding of the genetic underpinnings of plant reproductive ecology.
