MITOGEN‐ACTIVATED PROTEIN KINASE9 fine‐tunes hypoxia signaling by phosphorylating ERF‐VII transcription factors in Arabidopsis
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 (MA...

From root death to repatterning.
Today we heard @kevindaniel.bsky.social (from @hartman-plantlab.com) talk about Arabidopsis root shape plasticity under waterlogging stress.

Curious to hear more? You’ll have another chance next week at the ISRR Symposium.
