A mutation in protein phosphatase 2A regulatory subunit A affects auxin transport in Arabidopsis.

The EMBO journal - 1 May 1996

Garbers C, DeLong A, Deruére J, Bernasconi P, Söll D

Abstract excerpt

The phytohormone auxin controls processes such as cell elongation, root hair development and root branching. Tropisms, growth curvatures triggered by gravity, light and touch, are also auxin-mediated responses. Auxin is synthesized in the shoot apex and transported through the stem, but the molecular mechanism of auxin transport is not well understood. Naphthylphthalamic acid (NPA) and other inhibitors of auxin...
