Within 20 min of its application, auxin enhances the transport processes that move auxin molecules through coleoptfle tissue. The effect was observed after treatment with indoleacetic acid and a-naphthaleneacetic acid, but not with growth-inactive auxin analogues.
Treatment of etiolated zucchini (Cucurbita pepo L.) hypocotyl tissue with sub-micromolar concentrations of the cationophore monensin rapidly ( < 20 min) inhibited the transport catalytic activity of the specific auxin-anion efflux carrier and reduced the inhibition of this carrier by the phytotropin
