This week in Olomouc, we came together for an informal meeting on Kinetochore and Centromere. We shared ideas, did science, and strengthened collaborations. Many thanks to all the researchers who joined us. It was a great way to close the year by sharing knowledge, projects, and future perspectives.

📣Plant Meiosis Meeting is back for its second edition‼️ Save the date: 9–11 September 2026, Poznań, Poland🌱 More details coming soon🤩

Excited to share our latest paper showing how heat stress halts DNA replication and mitosis in barley roots! 🌡️🌱 #PlantScience #HeatStress #Barley www.frontiersin.org/journals/pla...

This week our group attended the TANGENC Conference 2025 at CEITEC in Brno. Our PI, David Kopecký, delivered a talk on “Disrupted cytonuclear stoichiometry in newly developed plant polyploids and hybrids."

How do new centromeres evolve while staying compatible with the division machinery? Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore. 👉 doi.org/10.1038/s41586-025-09779-1

How do plants control the genes needed for successful sexual reproduction? Our new work uncovers the DREAM complex as a crucial regulator of meiotic recombination in Arabidopsis. Without DREAM, plants are sterile—key recombination genes like MER3 are switched off...

New OA Article: "Hybridization and low-light adaptability in California eelgrass" rdcu.be/eNFeT Seagrass genomes of the deep-water Zostera pacifica and shallow-water Z. marina from the Eastern Pacific Ocean provide evidence for low-light adaptation.

We mourn the passing of our Editor-in-Chief Steve Long. His vision to establish one of the first journals dedicated to Global Change over 30 years ago was truly ahead of its time. Through GCB, researchers have demonstrated that biology and ecosystems are not simply victims of global change..

Great experience at Plant Chromosome Biology 2025 in Vienna 🌱 Congratulations to Jana Szecówka for being awarded Best Poster!

We’re excited to share our new work on how plants restore cytonuclear balance after whole-genome duplication. Using Arabidopsis auto- and allopolyploids, we uncover distinct, organelle-specific strategies in chloroplasts and mitochondria across generations. doi.org/10.1111/tpj....

A chromatin remodeling-independent role for #ATRX in protecting centromeric cohesion – Fangwei Wang and colleagues find an unexpected additional mechanism for preventing Wapl-mediated #cohesin release from mitotic centromere www.embopress.org/doi/full/10....

Just completed @embl.org Heidelberg’s intensive course on multi-omics data analysis. A highlight was network visualisation with Cytoscape led by Dr. Scooter Morris. Also, thanks to SEB for awarding the travel grant & to the @widehybridization.bsky.social for their support! #EMBLDataIntegration #SEB

Only one week left to register to the first conference on holocentric chromosomes, from cells to species! 🧬🪱🦋🌱 Join us in Switzerland on the 25-26 April 2025 Travel grants available! Register here: holocentricity.ch

Check out our most recent work elucidating the dynamics of genomic dominance in hybrids of Allium cepa × A. roylei. doi.org/10.1002/tpg2...

#Chloroplasts import 3,000+ nucleus-encoded proteins via TOC/TIC complexes and a motor system. This new #FreeAccess review highlights structural advancements, insights into #protein quality control and retrograde signaling, and more! doi.org/10.1111/jipb... #PlantScience 🔓

The kinesin motor POS3 and the microtubule polymerase MOR1 coordinate chromosome congression during mitosis in Arabidopsis (Yu Chen, Haofeng Liu, Yuanfeng Li, Xiao Shen, Shuting Li, Lan Yang, Xue An, et. al.) doi.org/10.1093/plce... #PlantScience

Viral delivery of recombinases activates heritable genetic switches in plants (James C Chamness, Jon P Cody, Anna J Cruz, Daniel F Voytas) doi.org/10.1093/plph... @ASPB #PlantScience

Do you love meiosis? Have a cool story to share? Join us for the XVth British Meiosis Meeting 26-27 of March in Liverpool! docs.google.com/forms/d/e/1F... You only have till Sunday to submit an abstract for a talk! ECRs are prioritised for speaking slots so the odds are in your favour 😁 #meiosis4eva

Very excited to share this new preprint from the lab (shorturl.at/l7lNq)! @hendersi.bsky.social si.bsky.social @camplantsci.bsky.social

Pecinka group has an opened PhD position to study genomic imprinting in barley! See below for more info. Friendly environment and beautiful city is a plus!

The joys of interspecific hybridisation - Arabidopsis thaliana x A. lyrata. The bamboo sticks are 60cm long (for comparison) and the flowers even smell nice!😍

Our PI David Kopecký was invited to give a talk at the 9th annual seminar of Plant Breeding Working Group of ETH in Zurich organized by Bruno Studer and colleagues. Great company from Andreas Weber, past CEPLAS speaker, Rene Geurts from Wageningen University, and friends from ETH and Agroscope!
