Cell polarity: PIN it down!

Curr Biol. 2011 Mar 8;21(5):R197-9. doi: 10.1016/j.cub.2011.01.062.

Abstract

How do plants create and maintain cell polarity? Recent studies reveal a plant-specific mechanism, which links the static cellulose-based extracellular matrix to the dynamic localization of PIN auxin carrier proteins.
