Abstract: Polar auxin transport is severely controlled in plants. The recent studies on regulation of polar auxin transport by flavonoids are reviewed. It is suggested that flavonoids act as negative regulators of auxin transport in vivo.

Key words: flavonoids, auxin, polar transport

摘要： 生长素在植物体内是通过极性运输方式输送的,这个运输过程是一个严格调控的过程。目前对其调控机理尚不了解。植物体内广泛存在的类黄酮类物质影响生长素运输,对生长素运输起负调控作用。
