Auxin inhibits expansion rate independently of cortical microtubules

Tobias I Baskin. Trends Plant Sci. 2015 Aug.

Abstract

A recent publication announces that auxin inhibits expansion by a mechanism based on the orientation of cortical microtubules. This is a textbook-revising claim, but as I argue here, a claim that is supported by neither the authors' data nor previous research, and is contradicted by a simple experiment.

Keywords: auxin-binding protein 1 (ABP1); growth direction; growth rate; microtubule orientation; tropism.
