Combinatorial expression of chacone synthase (CHS) and/or dihydroflavonol 4-reductase (BAN) and/or leucoanthocyanidine reductase (LAR) in plants to modify, for example, flavonoid biosynthesis

摘要

Disclosed are nucleic acid fragments encoding amino acid sequences for flavonoid biosynthetic enzymes in plants, and the use thereof for the modification of, for example, flavonoid biosynthesis in plants, and more specifically the modification of the content of condensed tannins. In particularly preferred embodiments, disclosed is the expression of chalcone synthase (CHS) and dihydroflavonol 4-reductase (BAN) and optionally leucoanthocyanidine reductase (LAR) in plants to modify, for example, flavonoid biosynthesis or more specifically the content of condensed tannins.
