Abstract

Objectives: Antiaris toxicaria is a tall tree belonging to the Moraceae family, known for its medicinal value. Its latex contains various cardiac glycosides, which hold significant research and potential application value. However, the lack of genomic resources for A. toxicaria currently hinders molecular genetic studies on its medicinal components. For its effective conservation and elucidation of the distinctive genetic traits of and medical components, we present its chromosome-level genome assembly.

Data description: Here, we assembled two haplotypes of A. toxicaria, including a 671.73-Mb HapA subgenome containing 27,213 genes and a 666.41-Mb HapB subgenome containing 28,840 genes. Their contig N50 sizes were 90.18 and 90.29 Mb, respectively. The transposable elements represented 61.15% and 64.13% of the total assembled genome in HapA and HapB subgenome, respectively. A total of 27,213 and 28,840 genes were predicted in the two haplotypes. Hopefully, this chromosome-level genome of A. toxicaria will provide a valuable resource to enhance understanding of the biosynthesis of medicinal compounds.

一种高质量的毒虫染色体水平基因组组装。

目的：毒藤是桑科的一种高大乔木，因其药用价值而闻名。其乳胶中含有多种心苷，具有重要的研究和潜在的应用价值。然而，毒草基因组资源的缺乏目前阻碍了其药用成分的分子遗传学研究。为了有效地保存和阐明其独特的遗传性状和医学成分，我们提出了其染色体水平的基因组组装。数据描述：在这里，我们组装了毒草的两个单倍型，包括671.73 mb的HapA亚基因组，包含27,213个基因和666.41 mb的HapB亚基因组，包含28,840个基因。它们的N50大小分别为90.18和90.29 Mb。在HapA和HapB亚基因组中，转座元件分别占总组装基因组的61.15%和64.13%。在这两种单倍型中，预计共有27,213和28,840个基因。希望这一染色体水平的基因组将为加强对药用化合物生物合成的理解提供有价值的资源。
