Inhibition of polar auxin transport by ethylene.
Applied ethylene influences the growth of etiolated pea stem sections cut from untreated plants, but has no effect on (14)C-indoleacetic acid uptake, polar transport or destruction. However, the capacity of the polar auxin transport system is markedly reduced in sections cut from plants grown in ethylene, while the velocity of auxin transport is unchanged under these conditions. Inhibition of t...
متن کاملKinetics of polar auxin transport.
The movement of auxin in the basipetal and acropetal directions is compared for 4 types of tissue. It is observed that the transport may proceed in either a linear or a non-linear manner with time. The polarity of transport through any given type of tissue increases exponentially with increasing lengths of tissue traversed, suggesting that the polarity of transport is developed as a consequence...

متن کاملA major facilitator superfamily transporter plays a dual role in polar auxin transport and drought stress tolerance in Arabidopsis.
Many key aspects of plant development are regulated by the polarized transport of the phytohormone auxin. Cellular auxin efflux, the rate-limiting step in this process, has been shown to rely on the coordinated action of PIN-formed (PIN) and B-type ATP binding cassette (ABCB) carriers. Here, we report that polar auxin transport in the Arabidopsis thaliana root also requires the action of a Majo...
متن کاملPolar Auxin Transport: Cell Polarity to Patterning
Auxin is a signaling molecule with profound influence on plant morphogenesis. Because of its activity gradient-related effects on plant development and response programs, it is considered as a plant morphogen. Auxin displays a spectacular ability to mobilize in a cell-to-cell and polar fashion. Auxin efflux carrier PIN proteins direct this intercellular flow of auxin and thus bear a ratelimitin...
