New research: With ancient origins & surprising flexibility, #BrownAlgae reveal a compelling story of sex chromosome evolution. This could rewrite how we view sex determination. Learn more: s.gwdg.de/YDoZ3L Congrats to @agalip.bsky.social & Josue Barrera for their work in @natecoevo.nature.com

Genomes of brown algae with different sex determination systems show that U/V sex chromosomes evolved 450–224 million years ago and show remarkable conservation of genes within the sex-determining region, despite independent expansions of the sex locus in each lineage www.nature.com/articles/s41...

Delighted to share the peer-reviewed version of our study led by @tomlewin.bsky.social now out in Genome Biology @bmc.springernature.com! We analyzed 64 chromosome-level genomes across 15 animal phyla and found that extensive genome rearrangements are the norm in bilaterians. doi.org/10.1186/s130...

💥🥳 At long last, our latest paper is out! Gag proteins of endogenous retroviruses are required for zebrafish development www.pnas.org/doi/10.1073/... Led heroically by Sylvia Chang & @jonowells.bsky.social A study which has changed the way I think of #transposons! No less! 🧵 1/n

Transposable elements in brown algae? 🌊 Yes, they’re full of surprises ✨ Come meet Ectocarpus at #ESEB2025! 📍Room 113 - S28.03 🗓️ Thursday, 2:30pm

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬 But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯 Our new study reveals how retrotransposons invade the germline directly from somatic cells. www.biorxiv.org/content/10.1... A short thread 🧵👇

DFAM (database of transposable elements) 3.9 is out! A lot of cool new stuff and a special update for Drosophila melanogaster... 1/2 #Transposon #DFAM

So happy to see @petrollromy.bsky.social first-author preprint at @biorxiv-genomic.bsky.social ✨ Could you imagine the impact of Plavaka elements on the genome expansion of Bostrychia moritziana? 🌊

In our latest @biorxiv-genomic.bsky.social preprint, we describe our approach to use PacBio HiFi reads to detect somatic TE transposition -- good enough to detect rare events that are present in only single cells. Led by Andrea Movilli. #plantscience www.biorxiv.org/content/10.1...
