One protein. One pathway. A whole germline fate. New paper from my postdoc @mpi-bio-fml.bsky.social out in PNAS: Germline fate determination by a single ARGONAUTE protein in Ectocarpus www.pnas.org/doi/10.1073/...

Germline fate determination by a single ARGONAUTE protein in Ectocarpus | PNAS

ARGONAUTE (AGO) proteins are a highly conserved family of RNA-binding proteins that play central roles in gene regulation and developmental process...

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

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9

Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics

Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.

Excited to share our new preprint on BioRxiv! A collaborative effort spanning many years and several labs to uncover what the germline chromosomes of Paramecium really look like. 🔗 www.biorxiv.org/content/10.1... 1/5

The tiny germline chromosomes of Paramecium aurelia have an exceptionally high recombination rate and are capped by a new class of Helitrons

Background. Paramecia belong to the ciliate phylum of unicellular eukaryotes characterized by nuclear dimorphism. A diploid germline micronucleus (MIC) transmits genetic information across sexual gene...

This Halloween, we have a spooky evolutionary story for you. The brainchild of @delaconcepcionjc.bsky.social, Nick Irwin and our fantastic collaborators is now out in @natplants.nature.com www.nature.com/articles/s41... Here’s why I love this work — and why I think you’ll enjoy it too. 👇

1/ Ever needed to annotate TEs in a fungal genome, but didn't know where to start? We have released #MycoMobilome, a community-focused non-redundant database of transposable element consensus sequences for the fungal kingdom, constructed from >4,000 fungal genomes! www.biorxiv.org/content/10.1...

Excited to introduce Auxenochlorella as a new algal reference organism for fundamental plant science and bioengineering. A paper in two parts: a genetic toolkit for site-specific genomic manipulation, paired with the most unusual genome I’ve ever worked on academic.oup.com/plcell/artic...

So happy to see my first first-author paper published! 🎈 A short thread on how Ectocarpus and its TE secrets have kept me busy lately: rdcu.be/eITQH

Fortunate to have played a small role in this project led by @caroleduchene.bsky.social. Phaeoviruses likely integrate into their host genomes using a promiscuous tyrosine recombinase, before reactivating in reproductive cells. Exciting to see diverse latency mechanisms emerging for giant viruses
