ERFVIIs as transducers of oxygen-sensing in the evolution of land plant response to hypoxia Short summary:This study investigates the evolution of the low-oxygen response in land plants mediated by group VII Ethylene Response Factors (ERFVIIs). We identified conserved transcriptional signatu...

How did oxygen-sensing evolve in plants?

Great to see this work published

VRN2-PRC2 facilitates light-triggered repression of PIF signaling to coordinate growth in Arabidopsis Osborne et al. show that the angiosperm-specific PRC2 subunit VRN2 is enriched in hypoxic regions of the Arabidopsis shoot, where it is required for stable deposition of H3K27me3 in key PIF4 target ge...

Happy to see our latest paper by @drosborneplantsci.bsky.social et al out today in Developmental Cell @cellpress.bsky.social! We identify a role for VRN2-PRC2 in regulating light-responsive growth in Arabidopsis through the conditional epigenetic repression of PIF signalling. tinyurl.com/swbyff24

Bluetorial: Light and Life: The incredible life of Lubert Stryer

I described my involvement with Lubert Stryer and how it led to one of the great opportunities of my life, taking over his textbook. Today, I detail his truly incredible life story.

Ubiquitin E3 ligases in the plant Arg/N-degron pathway
From @petermabbitt.bsky.social and Keely Oldham
A really informative and interesting review of the E3 ligases associated with the plant N-degron pathways

Flooding events are becoming increasingly common worldwide, therefore the research of @aidamaric.bsky.social is essential to understand the epigenetics caused by flooding stress. Plants primed by submergence or hypoxia show higher survival rates than naive plants under the second stress.

The letters "AI" overlaid with a red circle with a diagonal line through it.

I think the best thing I learned this week is to add " -ai" at the end of a search term in google. It works!

Subtilase SBT5.2 inactivates flagellin immunogenicity in the plant apoplast - Nature Communications Plants recognize bacteria by perceiving a 22-residue epitope in flagellin. Plant-secreted SBT5.2 subtilases are found to inactivate this epitope, leading to elicitor removal and reducing costly immuni...
