Abstract excerpt
Aglycone flavonols are thought to modulate auxin transport in Arabidopsis thaliana via an as yet undefined mechanism. Biochemical studies suggest that flavonoids interact with regulatory proteins rather than directly with the PIN auxin efflux facilitator proteins. Auxin transport is enhanced in the absence of flavonoids (transparent testa4 [tt4]) and reduced in the presence of excess flavonols (tt7 and tt3)....
