An oxygen-sensing Polycomb-group protein encodes flooding stress memory in plants

Most organisms, including plants, can encode stress memories that improve resilience to repeated environmental challenges. Flooding events expose plants to recurrent hypoxia, yet whether plants establ...

Flooding gives plants a big blow. In this week’s Plant & Zo roundup I talk about how one of the techniques plants use to recover from flooding. Further I talk about what auxin is and this week’s scientific articles and plant science in the media open.substack.com/pub/plantenz... 🧪 #PlantScience

Plant & Zo weekly roundup #22-2026

In which I talk about how plants after flooding treat young and old leaves different, what auxin is and this week’s scientific articles and plant science in the media

@carlos-rc.bsky.social together with @rimchaudhury15.bsky.social designed this figure describing some of the key temporal signalling events during a flooding event that were shown to contribute to differential stress resilience 🌱🌊 #plantscience

Circular schematic illustrating signalling events before, during and after plant submergence. The figure is divided into three interconnected phases arranged around a central ring labeled “Acclimation,” “Submergence,” and “Recovery,” with ethylene (Et) positioned at the center as a key regulator. The upper left region “Acclimation” depicts environmental flooding anticipation cues, including rain, waterlogging, humidity, and mechano-stimulation, leading to activation of EIN3 signalling. The upper right half, labeled as “Hypoxia,” represents submerged conditions with blue shading. Ethylene signalling through EIN2 stabilizes EIN3 and promotes accumulation of PGB1, which limits nitric oxide (NO)-dependent degradation of ERFVII transcription factors. Translation is globally repressed while stress-induced mRNA translation is promoted through GCN2. Sugar-dependent TOR signalling phosphorylates ERFVII, enabling interaction with MED25 and RNA polymerase II to activate hypoxia-responsive genes (HRGs). EIN3 also promotes ORE1-mediated senescence in old leaves, while miR164 suppresses ORE1 activity in young leaves. The lower left recovery section, shaded yellow, depicts re-oxygenation after flooding. Oxygen and hydrogen peroxide generated during a reactive oxygen species (ROS) burst stabilize ERFVII and activate oxidative stress-responsive genes (ORGs) while repressing HRGs. Ethylene signalling is attenuated through EBF-mediated ubiquitin–proteasome system (UPS) degradation and autophagic turnover of EIN3. Curved arrows around the outer circle indicate progression through flooding, hypoxia, and recovery, emphasizing that these signalling events are overlapping and interconnected rather than strictly linear.

Excited to see our #plantscience review published in @jxbotany.bsky.social! It really captures our lab’s perspective on how plants use spatiotemporal signaling under environmental contexts when floods occur, to coordinate acclimation responses and achieve stress tolerance. doi.org/10.1093/jxb/...
