PIN phosphorylation is sufficient to mediate PIN polarity and direct auxin transport.

Proceedings of the National Academy of Sciences of the United States of America - 12 Jan 2010

Abstract excerpt

The plant hormone auxin plays a crucial role in regulating plant development and plant architecture. The directional auxin distribution within tissues depends on PIN transporters that are polarly localized on the plasma membrane. The PIN polarity and the resulting auxin flow directionality are mediated by the antagonistic actions of PINOID kinase and protein phosphatase 2A. However, the contribution of the PIN...
