By cloning the genes from Arabidopsis halleri into A. thaliana, we first recapitulated the SI system in that model plant, with all its power to decipher the regulatory mechanisms.

Ever wondered what makes some alleles dominant (A) and others recessive (a) ? In our new paper, we explored how a series of recently discovered "dominance modifiers", genetic elements that have long remained elusive, achieve their regulatory function. journals.plos.org/plosgenetics...

2/Cardamine fruit rely on a polar secondary cell wall in the endocarp b layer to explode. C. chenopodiifolia also produces non explosive fruit with a uniform SCW. But if you exposed these underground fruit to light… Surprise! Their SCW pattern switches to polar and this make them explosive!💥

Happy to share the third chapter of my postdoctoral adventure at @mpipz.bsky.social ➡️doi.org/10.64898/2026.04.20.719616 We used C. chenopodiifolia's ability to produce explosive aerial fruit and non-explosive underground fruit to identify REVOLUTA's role in cell fate and wall patterning🌿💥 ⬇️🧵

I don’t know if you saw the MASSIVE news announced by @erc.europa.eu today: from now on, if you get a B at step 1 you are eligible to apply at N+3(!!!) years. Say you got a B in STG2026 step 1, you thought you could apply in STG2028, but no: only in STG2029! erc.europa.eu/news-events/...

I am thrilled and beyond grateful to receive a CNRS bronze medal this year - this is an incredible honour especially for an INRAE researcher like myself! A big thanks to my amazing team and the research community @RDP for all the great science we have done together!

It’s beginning. 🌵

Expert's Dilemma: the more specialized you become, the less open you are to creative solutions from other fields. But the more you explore other fields, the more you risk losing credibility in your home field. (Night Science recap, Day 3)

On en est arrivé là en France. C'est juste complètement fou. 🤦

📢 MicroRNA folks : We are looking for RNA-seq data comparing transcriptomes of mutants in which one particular miRNA locus of the genome was inactivated (by e.g. a tDNA insertion or by CRISPR) with their wt controls. Any hint ?

Our work on chromatin evolution in brown algae is now published in @natecoevo.nature.com! We show that developmentally complex brown algae evolved without epigenetic silencing pathways long thought universal, underscoring why non-model lineages are important to study. www.nature.com/articles/s41...

We have been cooking up this story for a while and we are excited to finally be able to share! Read on if you're interested in whole plant regeneration WITHOUT the application of hormones!

This is fascinating, and well worth a read. 🧪 www.forbes.com/sites/johndr...

Our paper is now out in PNAS! Crops often show boron deficiency in volcanic soils. Here, we identified six variants in two key boron transporter genes, BOR1 and BOR2, that increase leaf boron in natural populations of A. thaliana from volcanic islands in Cape Verde. www.pnas.org/doi/10.1073/...

Our work on the E3 ligase mechanism of target-directed microRNA degradation is now published! Amazing collaboration with Brenda Schulman’s lab led by @jakobfarnung.bsky.social and @elenaslo.bsky.social, with special thanks to @wyppeter.bsky.social, Lianne Blodgett, and Daniel Lin! tinyurl.com/Z8TDMD

I am happy to announce the launch of a new Arabidopsis genomics resource! Check out arabidopsislyrata.org Now you can easily look at the natural genetic variation across the entire species range of A. lyrata and A. arenosa.

The final part of the story: "The arduous path to obligate asexuality in Daphnia" is out in #ProcB 🥳 royalsocietypublishing.org/rspb/article.... 1. Instead of comparing long-established asexuals to sexuals, we generated new asexual lineages to observe the transition in action.

I am hiring a Postdoc (18 months contract in Montpellier, France) to study how polyploidy affects sex chromosomes in the plant Silene latifolia, using bioinformatic analyses of RNA-seq and DNA-seq data. Deadline for applications March 24th. euraxess.ec.europa.eu/jobs/412961

This is worth reading! A beautiful testimony of remembering why we chose to do science in the first place: curiosity and excitement, not pressure to publish and secure grants. Even if the research system always tells us otherwise!

In celebration of #BlackHistoryMonth let’s learn more about Marie Taylor, a plant biologist and chair of Howard University’s Botany Department. Love her focus on photomorphogensis and using light microscopy on living plants! 🌱 en.wikipedia.org/wiki/Marie_T...
