🌱🧬 SnRK2.6 phosphorylates and stabilizes PTRE1, which boosts 26S proteasome activity during ABA signaling. Loss of PTRE1 increases ABI5 levels and enhances ABA sensitivity.
A dual mechanism fine tunes ABA responses #plantscience @mplantpcom.bsky.social

This study reports that abscisic acid (ABA) activates sucrose nonfermenting 1-related
kinase 2.6 (SnRK2.6), which phosphorylates proteasome regulator 1 (PTRE1) and inhibits
its degradation, thereby st...
