The Rhus chinensis Genome Provides Insights Into Tannin, Flavonoid Biosynthesis, and Glandular Trichome Development

Plant Biotechnology Journal, EarlyView.
ABSTRACT The “salt tree”, Rhus chinensis, holds significant economic and medicinal value due to its ability to produce Galla chinensis (Chinese gall/gallnut), a plant‐derived medicinal material used in both traditional Chinese and modern medicine that is rich in tannins and flavonoids. It is also renowned for its remarkable stress tolerance.
