Les ScienceGuardians, fantômes de l’intégrité — TheMetaNews Un groupe d’activistes anonymes s’emploie depuis près d’un an à suivre, voire à menacer juridiquement, les détectives de l’intégrité scientifique. Chroniques d’une guerre invisible.

A lire, la contre attaque de la sphère complotiste/trumpiste contre ceux qui tente de debunker la fausse science. @themeta.news themeta.news/les-scienceg...

We would be happy to host a postdoctoral fellow with a projet related to metal homeostasis and accumulation in plants!

Symbiotic diversification relies on an ancestral gene network in plants Symbioses have been fundamental to colonization of terrestrial ecosystems by plants and their evolution. Emergence of the ancient arbuscular mycorrhizal symbiosis was followed by the diversification o...

1/ It is my pleasure to share the latest preprint of the team: "Symbiotic diversification relies on an ancestral gene network in plants"

doi.org/10.1101/2025...

Here, we identified and functionally validated a novel master regulator of intracellular symbioses!

I started to work on MscS-Like proteins 20 years ago, dreaming that they were involved in plant mechanotransduction. And it is becoming more & more clear that they are!

"DmMSL10 is crucial for mechanosensing, facilitating AP firing by generating a receptor potential (RP) amplitude."

Out after peer review, collaborative study from Nordborg & Weigel labs with help from many others. Not the largest collection of new Arabidopsis thaliana genomes, but we hopefully put forward some good ideas for how to think about pangenomes and their analysis!

NEW ARTICLE FROM THE LAB 🎉🍀🧫

Groundbreaking work performed by @hueihsuantsai.bsky.social and all!

Please, go have a read! Congrats to making it to the cover!!!

Engineered geminivirus replicons enable rapid in planta directed evolution Directed evolution can rapidly generate genetic variants with new and enhanced properties, yet efficient platforms for performing such evolution directly in plant cells have been lacking. We developed...

EPP1 is an ancestral component of the plant Common Symbiosis Pathway The success of plants on land has been enabled by mutualistic intracellular associations with microbes for 450 million years (Delaux and Schornack 2021). Because of their intracellular nature, the est...

Great story in collaboration with @pierremarcdelaux.bsky.social and @jeanmichelane.bsky.social groups. EPP1 story continues after many years of collaborations with Pierre-Marc and Jean-Michel!!!

Pendant des siècles, les plantes n’ont cessé de changer de nom, voici pourquoi cela est en train de s’arrêter Selon les époques et les naturalistes, de nombreuses plantes ont pu changer de nom et de famille.

Thank you Yohan ! Was so difficult for me to catch-up 🥵

Bryophytes hold a larger gene family space than vascular plants - Nature Genetics A super-pangenome analysis incorporating 123 newly sequenced bryophyte genomes reveals that bryophytes exhibit a larger number of unique and lineage-specific gene families than vascular plants.

A milestone for plant genomics just out @natgenet.nature.com

130 bryophyte genomes!

Gain and loss of gene function shaped the nickel hyperaccumulation trait in Noccaea caerulescens Nickel hyperaccumulation is an extreme adaptation to ultramafic soils observed in more than 500 plant species. However, our understanding of the molecular mechanisms underlying the evolution of this t...

Back online after few months of silence...
We had time to finalize our last paper
www.biorxiv.org/content/10.1...
where we describe the genome assembly of Noccaea caerulescens and provide new evidence for the role of IRT1 in nickel hyperaccumulation

...by the way, if you want to develop a Postdoctoral project with us on #metal #hyperaccumulation, the Toulouse University is opening the TIRIS AToUT Posdoctoral Fellowship program tiris.univ-toulouse.fr/en/programs/...
