Arabidopsis DELLA protein degradation is controlled by a type-one protein phosphatase, TOPP4.

PLoS genetics - 1 Jul 2014

Abstract excerpt

Gibberellins (GAs) are a class of important phytohormones regulating a variety of physiological processes during normal plant growth and development. One of the major events during GA-mediated growth is the degradation of DELLA proteins, key negative regulators of GA signaling pathway. The stability of DELLA proteins is thought to be controlled by protein phosphorylation and dephosphorylation. Up to date, no...
