Abstract excerpt
In plants, hypoxia sensing is controlled by the stabilization of group VII ethylene response factors (ERF-VIIs), which are post-translationally activated by the mitogen-activated protein kinases (MAPKs) MPK3 and MPK6. However, how plants fine-tune the MPK3/MPK6-mediated phosphorylation of ERF-VIIs to maintain cellular homeostasis remains largely unknown. Here, we show that the Arabidopsis thaliana TDY-type MAPK...
