So proud to see this story finally out!🎉 We added new data since our previous preprint—transgenic barley plants with an engineered immune receptor that fights off two fungal pathogens at once. Short 🧵 and link to the original preprint thread on X👇 www.science.org/doi/10.1126/...

Check out our latest pre-print on the evolution of TIR activity/signalling: www.biorxiv.org/content/10.6...

The unicellular Euplotes gigatrox typically exists in large populations of filter-feeding clones. However, some individuals grow to become “supergiants” that change shape, modify their locomotion, and begin cannibalizing their kin. In PNAS: https://ow.ly/HjeT50Z5Gbg

Canonical NLR immune receptor architecture enforces EDS1-dependency onto divergent TIR domains https://www.biorxiv.org/content/10.64898/2026.05.20.726525v1

Preprint Alert 🚨 @philcarella.bsky.social lab stepping into TIR-ritory!! Project started by me but finished by talented PhD student @ebkennedy.bsky.social (Please follow her), with contribution from Zhao He and @jonathandgjones.bsky.social We investigated EDS1-dependency of TIR domain. See thread👇

@khongsamchia.bsky.social Extremely excited to share the first pre-print from my PhD project in the Carella lab, co-first authored with @khongsamchia.bsky.social 🎉 (Thread below ⬇️) www.biorxiv.org/content/10.6... Huge thanks to all co-authors and the #CarellaCapybaras for all the support 😊

Although the red pigments made by flowering plants and liverworts are produced by distinct chemical pathways, here we found that they are induced by homologous complexes of transcription factors. @currentbiology.bsky.social

Final version of our NRG1 MS is out! We uncover a surprising mechanism: the helper NLR NRG1 targets organellar membranes to trigger immunity Great collaborations with @KamounLab, @JiorgosKourelis, @jonathandgjones, @AdamWu9527, and the @Phil_Carella labs! science.org/doi/10.1126/sc…

We are very happy and proud to present a study led by @jorgehg.bsky.social (now PI in Madrid – keep an eye on him!) in our team @bic-wur.bsky.social. In this work, we discover how auxin-regulated ARF transcription factors learned to activate transcription. A 🧵…(1/17) www.biorxiv.org/content/10.6...

The last paper of my PhD work in Argentina. We dig deeper into the Marchantia MpC1HDZ transcription factor. Many experiments, but my favourite: in addition to its role in oil body cell differentiation, it is also important for another cell type! #PlantScience academic.oup.com/plphys/advan...

The final version of our Marchantia cell cycle paper is now published. A much improved version compared to the preprint. Cyclins, repressors, and more. Thanks to co-authors and reviewers. #PlantScience. academic.oup.com/plcell/advan...

just want to thank again @grandpahiro.bsky.social & @huguesrenault.bsky.social for saving us from an embarrassment: “We thank Hirofumi Nakagami and Hugues Renault for their feedback on not defining Marchantia polymorpha as an early land plant.” www.cell.com/developmenta...

We’re in for a treat today. Our seminar speaker is Christine Strullu-Derrien: “Early terrestrial microorganisms revealed through advanced imaging techniques.” Exploring the insane hundreds-of-millions-of-years timescales that we rarely think about.

New Preprint! Engineering quantitative root disease resistance in barley by targeting conserved SCAR susceptibility genes without compromising seed yield or mycorrhizal symbiosis. This work has been led by @binebrumm.bsky.social www.biorxiv.org/content/10.6...

🚨 New Preprint! 🚨 For my PhD, I investigated an over 20-year-old mystery in photosynthesis: What does the highly conserved but enigmatic protein cytochrome c6A actually do? We found: c6A helps algae stayin' alive in the "DISCO". 🪩 See the thread below & read the preprint: doi.org/10.64898/202...

Marchantia might seem an unlikely biotech crop, but it’s worth trying. In Aurore’s thesis, we pushed this concept by engineering the auronidins with MpMYB14 and using the pigments to dye cotton. It ended up giving a very unique and beautiful product. #PlantScience www.biorxiv.org/content/10.6...
