Letters: Auxin and vesicle traffic (Plant Physiol)

Three letters to Plant Physiology address the role of vesicles in auxin transport, discussing the evidence and conclusions from a recently published paper from three perspectives. Does auxin accumulate in endocytic vesicles? If so, how, and why? The Letters address both the methods used and the intrepetation of the study’s results. This link takes you to a Letter by Robinson et al., and a Rebuttle by Baluška et al. This link takes you to another Letter by Hertel on the question of auxin in vesicles.  (Summary by Mary Williams) Plant Physiol.
