- Reposted by Ferdinand MarlétazOur work on the evolution of the regulatory genome of echinoderms is now out in @natecoevo.nature.com. Led by my former PhD Marta Magri, Danila Voronov & Saoirse Foley. Great collaboration of Arnone, Hinman & Maeso labs, started long time ago with our missed José Luis Gomez-Skarmeta: rdcu.be/eXX8l

- Reposted by Ferdinand MarlétazOut 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
- Reposted by Ferdinand MarlétazGene annotations matter for downstream analyses: different structural gene-annotation pipelines yield markedly different orthology calls. We compare four strategies across species and argue for standards & QC before inference. Work led by @silviaprietob.bsky.social. Paper: doi.org/10.1093/bioi...
- Reposted by Ferdinand MarlétazPleased to share our latest paper led by @tomlewin.bsky.social, now out in @currentbiology.bsky.social! We present the first chromosome-level genome of a phoronid and show that shared chromosomal fusions unite phoronids and bryozoans as sister groups. www.cell.com/current-biol...

- After nearly twenty years in the making, our attempt at understanding what makes the chaetognath phylum so unique has finally been published! www.nature.com/articles/s41... with #LauraPiovani @dariagavr.bsky.social @alexdemendoza.bsky.social @chemamd.bsky.social and others /1
- We found that chaetognath genome is as puzzling as their body plan with extensive shuffling of gene repertoire, lots of gene novelty and loss, without evidence of WGD, which appear to be involved in the making of lineage-specific cell types /2

- Reposted by Ferdinand MarlétazATLASea Mission – Day 6 In the dissection room, the final sampling steps are underway 🔬 Tissue fragments are collected, labeled, weighed, and logged into a data sheet for full traceability ❄️ Samples are flash-frozen in liquid nitrogen at -196°C to preserve DNA quality for sequencing at Genoscope
- Reposted by Ferdinand MarlétazI am looking for a new postdoc to join the lab. Interested in pluripotency, germ cells, and in investigating these in a genetically tractable cnidarian? Get in touch! We offer a long-term contract, excellent research environment, and a lovely city #Galway. www.urifranklab.org

- Reposted by Ferdinand MarlétazCheck out our latest work‼️Fantastic study with really cool data and findings led by @allancarbal.bsky.social in collaborarion with Stephan’s lab. The one and many ways of getting a belly…
- It's finally here! Great start of the summer. We got our latest preprint from @chemamd.bsky.social in @qmulsbbs.bsky.social @qmulse.bsky.social, showing evidence of developmental system drift in the specification of dorsoventral (belly vs back) axis in annelids 🪱🪱🪱 #DevBio #EvoDevo
- So glad to see this work on single cell of squid visual system finally published in @natecoevo.nature.com , a long adventure from Okinawa to London !

- Reposted by Ferdinand MarlétazIt was a pleasure to write a N&Vs on @danielibrahim.bsky.social's latest paper in @natgenet.nature.com. Enhancers tend to stay put even if their sequence changes beyond recognition. Quoting Il Gattopardo, everything must change so that everything can stay the same: www.nature.com/articles/s41...

- Reposted by Ferdinand MarlétazPostdoc job opportunity! We're looking for ECR in evolutionary genomics to study the relation between intra-specific gene expression variability, polymorphism, and macro-evolutionary rates. We have the data in 3 fishes & amphioxus, just waiting for your expertise and enthusiasm! tinyurl.com/3aewk286
