High Quality Chromosome Level Genome Map of Heshouwu (Fallopia multiflora (Thunb.) Harald.)

Heshouwu (Fallopia multiflora (Thunb.) Harald.) is a commonly used tonifying medicinal herb in clinical practice, with a medicinal history of over a thousand years. It is the dried root tubers of Polygonum multiflorum, a perennial plant in the family of Polygonaceae. Fallopia multiflora contains rich chemical components, with stilbene glycoside as its core functional component and also an indicator component specified in the Chinese Pharmacopoeia. However, the lack of high-quality genome maps of Polygonum multiflorum limits the study of its material basis formation mechanism.

Recently, a study conducted on wild diploid Polygonum multiflora (Thunb.) Harald (2n=2x=22) as the material, using Illumina, Pacbio, 10×Genomics and Hi-C techniques were used to mount approximately 1.44 Gb of genome sequences onto 11 chromosomes, resulting in high-quality chromosomal level genome assembly and functional annotation.
This study not only provides references for revealing the biosynthetic pathway of stilbene glycosides, but also provides rich genetic resources for future research on Polygonum multiflorum.
