Localization of the auxin permease AUX1 suggests two functionally distinct hormone transport pathways operate in the Arabidopsis root apex
Auxins represent an important class of plant hormone that regulate plant development.
Plants use specialized carrier proteins to transport the auxin indole-3-acetic acid (IAA) to
target tissues. To date, efflux carrier-mediated polar auxin transport has been assumed to
represent the sole mode of long distance IAA movement. Localization of the auxin permease
AUX1 in the Arabidopsis root apex has revealed a novel phloem-based IAA transport
pathway. AUX1, asymmetrically localized to the plasma membrane of root protophloem …
