Flueggea virosa (Roxb. ex Willd.) Royle, an evergreen shrub and small tree in the Phyllanthaceae family, holds significant potential in garden landscaping and pharmacological applications. However, the lack of genomic data has hindered further scientific understanding of its horticultural and medicinal values. In this study, we have assembled a haplotype-resolved genome of F. virosa for the first time. The two haploid genomes, named haplotype A genome and haplotype B genome, are 487.33 Mb and 477.53 Mb in size, respectively, with contig N50 lengths of 31.45 Mb and 32.81 Mb. More than 99% of the assembled sequences were anchored to 13 pairs of pseudo-chromosomes. Furthermore, 21,587 and 21,533 protein-coding genes were predicted in haplotype A and haplotype B genomes, respectively. The availability of this chromosome-level genome fills the gap in genomic data for F. virosa and provides valuable resources for molecular studies of this species, supporting future research on speciation, functional genomics, and comparative genomics within the Phyllanthaceae family.
羽叶榕（Flueggea virosa）为叶下珠科常绿灌木或小乔木，在园林景观和药理学应用方面具有很大的潜力。然而，由于缺乏基因组数据，其园艺和药用价值的科学研究受到了限制。在本研究中，我们首次组装了羽叶榕的单倍型 resolved 基因组。这两个单倍体基因组，分别命名为 haplotype A 基因组和 haplotype B 基因组，大小分别为 487.33Mb 和 477.53Mb，contig N50 长度分别为 31.45Mb 和 32.81Mb。组装序列的 99%以上被锚定到 13 对假染色体上。此外，在 haplotype A 和 haplotype B 基因组中分别预测到了 21587 个和 21533 个蛋白编码基因。该染色体水平基因组的提供填补了羽叶榕基因组数据的空白，为该物种的分子研究提供了有价值的资源，支持了叶下珠科内种形成、功能基因组学和比较基因组学的未来研究。
