The first PhD student in the group to graduate since I moved to Oxford! So proud for all the excellent work she did, and grateful for her contribution to a warm and friendly atmosphere in the team (and the taralli!)

Group 7 (again!) histone demethyalses (KDM7s) use oxygen as a substrate and are hypoxia sensitive. Under hypoxia, H3K4me3 increases globally in the plant and in root tips this causes activation of a number of genes that enhance tolerance

Our study led by the extraordinary multitasking Daai Zhang shows here (tinyurl.com/3uhbkh54) that an additional O2 sensing mechanism based on histone methylation helps roots to prepare for potentially lethal hypoxic stress (such as in waterlogging)

Hydrogen sulfide modulates plant hypoxic responses through the persulfidation of Plant Cysteine Oxidases Hydrogen sulfide (H₂S) is a gaseous molecule historically regarded as toxic. Nevertheless, increasing evidence has brought to light important physiological roles in both animals and plants. In plants,...

Happy to share the key part of my PhD! In our latest preprint with Salma Akter, @emilyflashman.bsky.social & @beagiuntoli.bsky.social, we show that H₂S is involved in oxygen sensing in plants!
How? Check it out!🌱✨

Many thanks to all the authors involved!

Great to see this out (as a preprint, for the moment)! And thank you for the opportunity to contribute to this new exploration of the connection between oxygen sensing and shoot development 🍃

Thank you Thomas! @ximenachirinos.bsky.social studied what happened to the O2 sensing machinery in flowering plants that are constantly or near-never.submerged. Spoiler: she discovered new PCOs and weird ERFVIIs...

Congratulations Vinay!!! Hard to describe how happy I am about this, except for the fact you'll leave Oxford soon 🥲.

Introducing the 1,000 Flower Collection 🧬🌹

I’m creating 1,000 genetically designed flowers each crafted with new colors, patterns, and shapes.

Here’s how I’m making it happen… and how you can join me on this journey 🧵(1/7)

Gas leakage triggers wound healing in plants

A plant's protective outer barrier is nearly impermeable to gases, making ethylene build up inside while oxygen depletes. But when wounded, the dynamics shift 🌱

New research shows this movement of gases through a wound triggers the plant's healing process 👇

@vinayshukla.bsky.social

Plants "bleed" too, but through gases!
When wounded, ethylene leaks out and oxygen seeps in. This gas shift acts as an alarm, triggering self-repair to seal the breach. Excited to share our new collaborative work uncovering this clever plant mechanism! Excellent summary here, indulge!
#plantscience

An exciting collaboration that has reignited @vinayshukla.bsky.social's interest for hypoxia and roots! Really happy that we could contribute! @isplore.bsky.social

Only our joint forces, @lauradc.bsky.social 's perseverance and the contribution of Hans van Veen, @vinayshukla.bsky.social, Monica Perri and Liem T. Bui could tackle this challenge with many plant species and several transgenic lines! It's really satisfying to see it published!

C-terminal amides mark proteins for degradation via SCF–FBXO31 - Nature SCF–FBXO31 scans proteins for C-terminal amidation and marks them for subsequent proteasomal degradation.

🎉Super excited to share our story on how the substrate receptor FBXO31 functions as a quality control factor by recognizing amides. This has been an amazing collaboration between Bode lab and @jcornlab.bsky.social. Special shutout goes to @matthiasmuhar.bsky.social www.nature.com/articles/s41...

The diverse aspects of hypoxia. The size of the oxygen bubble correlates with concentration. This collection highlights the importance of hypoxia for plant development and environmental adaptation such as during flooding, in compacted or poorly aerated soils, high altitudes, and within meristematic tissues.

With our new study, we engineered an orthogonal hypoxia-responsive system in plants inspired by mammalian HIF protein degradation. We demonstrated that this system could control protein stability and activity, enabling modulation of Oxygen sensing outputs. Here's how:
