ATR and MKP1 play distinct roles in response to UV-B stress in Arabidopsis.

The Plant journal : for cell and molecular biology - 1 Mar 2013

González Besteiro Marina A, Ulm Roman

Abstract excerpt

Ultraviolet-B (UV-B) stress activates MAP kinases (MAPKs) MPK3 and MPK6 in Arabidopsis. MAPK activity must be tightly controlled in order to ensure an appropriate cellular outcome. MAPK phosphatases (MKPs) effectively control MAPKs by dephosphorylation of phosphothreonine and phosphotyrosine in their activation loops. Arabidopsis MKP1 is an important regulator of MPK3 and MPK6, and mkp1 knockout mutants are...
