The near-complete genome assembly of Reynoutria multiflora reveals the genetic basis of stilbenes and anthraquinones biosynthesis
Reynoutria multiflora is a widely used medicinal plant in China. Its medicinal compounds are mainly stilbenes and anthraquinones which possess important pharmacological activities in anti-aging, anti-inflammatory and anti-oxidation, but their biosynthetic pathways are still largely unresolved. Here, we reported a near-complete genome assembly of R. multiflora consisting of 1.39 Gb with a contig N50 of 122.91 Mb and only one gap left. Genome evolution analysis revealed that two recent bursts of long terminal repeats (LTRs) contributed significantly to the increased genome size of R. multiflora, and numerous large chromosome rearrangements were observed between R. multiflora and Fagopyrum tataricum genomes. Comparative genomics analysis revealed that a recent whole-genome duplication specific to Polygonaceae led to a significant expansion of gene families associated with disease tolerance and the biosynthesis of stilbenes and anthraquinones in R. multiflora. Combining transcriptomic and metabolomic analyses, we elucidated the molecular mechanisms underlying the dynamic changes in content of medicinal ingredients in R. multiflora roots across different growth years. Additionally, we identified several putative key genes responsible for anthraquinone and stilbene biosynthesis. We identified a stilbene synthase gene PM0G05131 highly expressed in roost, which may exhibit an important role in the accumulation of stilbenes in R. multiflora. These genomic data will expedite the discovery of anthraquinone and stilbenes biosynthesis pathways in medicinal plants.
期刊介绍:
Journal of Systematics and Evolution (JSE, since 2008; formerly Acta Phytotaxonomica Sinica) is a plant-based international journal newly dedicated to the description and understanding of the biological diversity. It covers: description of new taxa, monographic revision, phylogenetics, molecular evolution and genome evolution, evolutionary developmental biology, evolutionary ecology, population biology, conservation biology, biogeography, paleobiology, evolutionary theories, and related subjects.
