Abstract
The traditional Chinese medicinal plant Fallopia multiflora (hereafter AYY) is well known for its anti-hyperlipidaemia, immunomodulating, and hepatoprotective effects, attributed to its abundance of anthraquinones and stilbene glycosides, which are distinct to its variety F. multiflora var. angulata (hereafter CYY) in proportion and composition. In this study, telomere-to-telomere (T2T) genomes were assembled for AYY and CYY using PacBio HiFi reads and Hi-C data. The genome sizes, percentages of repetitive sequences, and numbers of protein-coding genes of AYY and CYY assemblies were 1,458.37 Mb/70.48%/84,768 and 1,174.38 Mb/67.36%/69,100, respectively. Comprehensive assessments confirmed high continuity (contig N50: 112.58 Mb and 94.83 Mb; number of gaps: 9 and 5), completeness (BUSCOs: 97.30% and 97.60%; LAI: 16.93 and 16.77), and correctness (QV: 51.42 and 52.60) of AYY and CYY assemblies. These T2T genomes of F. multiflora provide valuable resources for studying the biosynthesis of specialized metabolites and facilitating precise genetic improvement.
