摘　　要：Proanthocyanidins(PAs)are natural flavan-3-ol polymers that contribute protection to plants under biotic and abiotic stress,benefits to human health,and bitterness and astringency to food products.They are also potential targets for carbon sequestration for climate mitigation.In recent years,from model species to commercial crops,research has moved closer to elucidating the flux control and channeling,subunit biosynthesis and polymerization,transport mechanisms,and regulatory networks involved in plant PA metabolism.This review extends the conventional understanding with recent findings that provide new insights to address lingering questions and focus strategies for manipulating PA traits in plants.
