Persicaria tinctoria (2n = 40) is an important traditional medicinal plant and natural dye source within the genus Persicaria. P. tinctoria has been utilized for its antibacterial, antiviral, anti-inflammatory, and tumor treatment properties. Additionally, it has served as a natural blue dye for thousands of years worldwide, and continues to be used in countries such as China and Japan. Here, we assembled a tetraploid chromosome-scale genome of P. tinctoria, organized into two subgenomes: subgenome A, which contains 10 pseudochromosomes with a genome size of 888.67 Mb and a scaffold N50 of 90.56 Mb, and subgenome B, which also comprises 10 pseudochromosomes with a genome size of 771.58 Mb and a scaffold N50 of 76.84 Mb. Repeat sequences constitute 77.9% of the genome. A total of 76,742 high-confidence protein-coding genes were annotated, with 94.28% of these genes assigned functional annotations. This high-quality genome assembly of P. tinctoria will provide valuable genomic resources for studying the biosynthesis and evolution of indigoids in indigo plants, as well as for further research on the Polygonaceae family.
虎杖（2n = 40）是蓼属中一种重要的传统药用植物和天然染料来源。虎杖因其抗菌、抗病毒、抗炎和肿瘤治疗特性而被利用。此外，它在全球范围内已作为天然蓝色染料使用了数千年，并且在中国和日本等国家仍在使用。在此，我们组装了虎杖的四倍体染色体水平基因组，其被组织成两个亚基因组：亚基因组A，包含10条假染色体，基因组大小为888.67 Mb，支架N50为90.56 Mb；亚基因组B，也由10条假染色体组成，基因组大小为771.58 Mb，支架N50为76.84 Mb。重复序列占基因组的77.9%。总共注释了76742个高可信度蛋白质编码基因，其中94.28%的基因被赋予了功能注释。虎杖的这种高质量基因组组装将为研究靛蓝植物中靛类化合物的生物合成和进化以及蓼科的进一步研究提供有价值的基因组资源。
