Excited to share my latest work in @newphyt.bsky.social. Here, we used TurboID proximity labeling with CLAVATA receptors FEA3 and BAM1D in maize meristems to better understand the signaling pathways important for meristem regulation. #PlantScience

Coming soon! PhD opening joint with @drjonbaxter.bsky.social at @gdsc-sussex.bsky.social
Keep a look out and get in touch if you are interested in any and all of: Chromosomes, Genome Stability, Chromatin and DNA Topology in Mitosis and Meiosis.

🌱 EPIPLANT is live!

Registration is now open for the EPIPLANT 2026 conference (June 22–25).

We look forward to welcoming you to Nantes, France for an exciting conference on the epigenetics of photosynthetic organisms!

I’ll be spending the next four weeks at @agroscope.bsky.social Changins, working on the eccDNA identification in Arabidopsis. Big thanks to @plantepigenetics.ch who agreed to host me and OPJAK Tangenc @iebcas.bsky.social for funding the mobility 😉 🌱🥼🔬

A zz plant in a brown plot. The plant has waxy lush green leaves.

Today I learned that the common houseplant Zamioculcas (the zz plant) is monocot w/ pinnately compound leaves. So called leaves are in fact leaflets. Unlike most species w/ compound leaves, the leaflets of zz plants are highly regenerative, from which whole plants can be readily regenerated.

The HeatDDR doctoral network training school in full swing @iebcas.bsky.social @pecinka-grp.bsky.social @zeiss-microscopy.bsky.social #microscopy #DNAdamage

📢 Three new #bioRxiv preprints from our team on holocentric chromosomes.

Together, they connect centromere repeat evolution, karyotype dynamics, and meiotic recombination outcomes, revealing how holocentric genomes evolve and function. 🧬👇

We are hosting the training school of the HeatDDR PhD program over this week at the Center for Structural and Functional Plant Genomics of the Institute of Experimental Botany, Olomouc! 🧬

Doctoral students of the network from all over Europe will learn cutting edge techniques related to DNA damage!

Excited to share our latest paper showing how heat stress halts DNA replication and mitosis in barley roots! 🌡️🌱 #PlantScience #HeatStress #Barley

Starting off the new year with a kick-off meeting of a new collaborative grant with
Jan Paleček from Brno. We're excited to unravel how new candidates of DNA damage repair work their magic in Arabidopsis! ☘️ 🧪 🧬

P.S. Good brainstorming needs good pizza🍕

🌟 Wrapping up the year with Christmas sweets and mulled wine at our final lab meeting before Christmas! 🎄#HappyHolidays

❄️Proper Winter is here!!! ❄️
So we had to try out the snow. ⛷️🏂

We're thrilled to welcome Manuel Escalona Sendín from Spain to our group! Manuel will be diving into the effects of temperature stress on DNA damage in barley. #HeatDDR
He's already sampled Czech cuisine and beer 🍻—and even a snowballs fight! ❄️ #phdlife

Starting on September, 2026, our doctoral student will be a part of the Marie Sklodowska-Curie Actions Doctoral Network Consortium AGILE, involving leading European Labs in advanced microscopy of plant chromosomes.

🧪☘️🧬

We're thrilled to announce our new PhD position in the AGILE Doctoral Network on nuclear lamina's role in the maintenance of Rabl configuration in barley!🔬🌾🧬

Identification d’un mécanisme global de répression de la transcription chez la plante modèle Arabidopsis thaliana Dans une étude publiée dans PNAS, l’équipe Dynamique des Chromosomes de l’Institut des Sciences des Plantes de Paris-Saclay - IPS2 (CNRS/INRAE/UEVE/UPSaclay, Gif-sur-Yvette) met en évidence l’existence d’un mécanisme global de répression de la transcription chez la plante modèle Arabidopsis thaliana.   À l’aide d’un crible génétique, les chercheurs ont montré que la protéine LUMINIDEPENDENS (LD) intervient dans la réponse au stress réplicatif. L’analyse de ses cibles, réalisée par immunoprécipitation de la chromatine et des approches transcriptomiques normalisées par spike-in, révèlent que LD agit comme un régulateur négatif de la transcription à l’échelle du génome.   L’étude de ses partenaires protéiques suggère que LD module la transcription par divers mécanismes, notamment la modification des histones, la phosphorylation de l’ARN polymérase II ou encore son recrutement sur la chromatine par le complexe Mediator.   Ainsi, LD apparaît comme un régulateur global de la transcription, dont le rôle dans la réponse au stress réplicatif pourrait s’expliquer par une réduction des conflits transcription-réplication, sources majeures de stress réplicatif et d’instabilité génomique.   -> Contact : cecile.raynaud@universite-paris-saclay.fr

Fig. 1 (shortened, full legend in paper): Complexity of gynoecium development shown with confocal microscopy imaging. (A) Meristematic stages of floral development in which the inflorescence meristem (IM) is observed; from stage 3, the sepal primordia (asterisks) are observed; in stage 4, the developing sepals (asterisks) partially cover the floral meristem (FM); and in stage 5, the FM is completely covered by the sepals. (B) Stage 6 in which the gynoecium is established with the appearance of the primordium of the gynoecium. (C) In stage 7, the middle and lateral domains can be differentiated (marked by dotted lines). (D–H) Longitudinal view of the gynoecium from stage 8 to 12. At stages 8 and 9, the gynoecium grows as a hollow tube and the valves and young replum can be seen. (F and G) Longitudinal view of stage 10 and 11 gynoecia showing the replum and valves. (H) Mature stage 12 gynoecium showing the stigma, style, and ovary, the latter formed by the valves and replum.
