METHODS FOR REGULATING EXTRACTABLE PROANTHOCYANIDINS (PAS) IN PLANTS BY AFFECTING LEUCOANTHOCYANIDIN REDUCTASE (LAR)

摘要

Adjustments to the amount of soluble and insoluble proanthocyanidins (PAs) in plants can be accomplished through regulation of leucoanthocyanidin reductase (LAR) functionality. Reducing LAR functionality increases epicatechin polymerization, leading to greater amounts of insoluble PAs and effects on astringency and other characteristics.
