By Owens, Daniel K Alerding, Anne B; Crosby, Kevin C; Bandara, Aloka B; Westwood, James H; Winkel, Brenda S J The genome of Arabidopsis (Arabidopsis thaliana) contains five sequences with high similarity to FLAVONOL SYNTHASE1 (AtFLS1), a previously characterized flavonol synthase gene that plays a central role in flavonoid metabolism. This apparent redundancy suggests the possibility that Arabidopsis uses multiple isoforms of FLS with different substrate specificities to mediate the...
