Auxin Transporters Controlling Plant Development

Part of the Signaling and Communication in Plants book series (SIGCOMM, volume 7)


The plant hormone auxin regulates many important aspects of plant development from the early embryogenesis to the seed production. On genomic and nongenomic levels, finely tuned auxin gradients form an important morphoregulatory trigger. In planta, auxin is transported to long distances using symplastic transport in the phloem. Besides, it is also a subject to the cell-to-cell transport, being able to move across the plasma membrane (PM) by diffusion and/or utilizing several types of auxin transporters. The role of the PM-localized auxin influx and efflux carriers lies mainly in the fast directional transport of auxin across the PM forming the basis for the establishment of developmentally significant auxin gradients. In addition to PM-localized auxin transporters, there is also a population of intracellular auxin transporters, which are probably involved in the regulation of auxin homeostasis and thus in the control of availability of free auxin molecules. This chapter summarizes recent knowledge on the types of auxin transporters, their functional characterization, and involvement in developmental processes in plants.
