Abstract
Several derivatives of 2-(1’,3’-dioxo-3’-phenylpropyl)phenylacetic acid, a homolog of the auxin transport inhibitor 2-(1’ ,3’-dioxo-3’-phenylpropyl)benzoic acid (CPD), were synthesized. The phenylacetic acids with a heterocyclic ring such as isoxazole between the two phenyl groups inhibited the growth of lettuce, rice, and buckwheat. They prevented the active movement of auxin within the bean segments and abolished the root geotropic response of lettuce seedlings, as well as auxin transport-inhibiting benzoic acids. These phenylacetic acids may be intrinsic inhibitors of auxin transport.
