Diploid origins and early genome stabilization in the allotetraploid Arabidopsis suecica Burns et al. [email protected] [email protected] nph.onlinelibrary.wiley.com/doi/10.1111/...

Very excited to share our work published in Nature Comms last week! Here we describe a range of cool things that can be done once you have the power to control deposition of H3K4me3… rdcu.be/eNEf4 A short thread:

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from? Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria. www.biorxiv.org/content/10.1...

In these dark times, it comes as a rare pleasure to highlight @natanaels.bsky.social ‬ & @marcdemanuel.bsky.social's work on germline and somatic mutations in humans. 1/n www.biorxiv.org/cgi/content/...

Out after peer review, collaborative study from Nordborg & Weigel labs with help from many others. Not the largest collection of new Arabidopsis thaliana genomes, but we hopefully put forward some good ideas for how to think about pangenomes and their analysis! www.nature.com/articles/s41...

1/ How do animals develop immunity against a newly encountered transposable element from scratch? Our study reveals that the mobility of TEs is their Achilles heel, allowing hosts to develop a powerful small RNA-mediated silencing response. www.biorxiv.org/content/10.1...

Just out in Science: we demonstrate a micro-evolutionary shift in a single generation, involving thousands of genomic loci, giving younger ash trees more resistance to ash dieback, on average, than their parents www.science.org/doi/10.1126/science.adp2990

Thrilled to share our new paper in @science.org describing our discovery that bacteria can switch from competitors to bonafide predators when resources run dry—arming nanoscale “spears” (T6SS) to stab & consume neighbours. www.science.org/doi/10.1126/... #MicroSKy #Microbiology

Life-history trade-offs explain local adaptation in Arabidopsis thaliana https://www.biorxiv.org/content/10.1101/2025.05.18.654693v1

Excited to share our work on using pathway-specific polygenic scores to discover gene-environment interactions www.medrxiv.org/content/10.1...

. @pnas.org just published the final version of our manuscript on how generation time and effective population size interact to shape vertebrate germline mutation rates, led by Luke Zhu and Annabel Beichman: www.pnas.org/doi/10.1073/...

New research by @egonzalezduran.bsky.social shows that DSB repair suppresses gene transfer from chloroplasts to nucleus. With DSB repair impaired, transfer rates jump 20× — revealing how plants protect genome stability, with lessons beyond plant biology. Read: nature.com/articles/s41477-025-02005-w

I'm so very excited to see this out - a single cell and spatial transcriptomic analysis in the rice root reveals mechanisms by which roots can respond to different below-ground growth conditions - including compaction. Congratulations to everyone for persisting in difficult times. rdcu.be/ej8Ui

Awesome new paper by @lucalivraghi.bsky.social et al. doi.org/10.1016/j.cu... in @currentbiology.bsky.social on the evo-devo of a butterfly color variation enjoy the show!

It’s 🌿International Plant Appreciation Day🌿, so here’s a Corydalis melanochlora from the Hengduan Mountains. I can’t stop praising my favorite alpine flora 🥰 #LetsGoPlants #IamaBotanist

Our new paper on the rapid evolution of centromeres in Drosophila is out! 🚀 Discover how transposable elements and satellite DNAs shape centromere dynamics and drive karyotype evolution over short timescales. @amlarracuente.bsky.social 🌟 Check it out here: journals.plos.org/plosbiology/...

Our paper on ancient human population structure is now published. We find that the ancestors of modern humans lived in multiple populations during the period when Homo sapiens evolved in Africa. www.nature.com/articles/s41...

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 🧵👇

We have a funded PhD position available in Exeter @exeter.ac.uk Gene Regulation in Brain Development and Disease 🧬 Please share / repost www.exeter.ac.uk/study/fundin...

Excited to share a couple of new items (links below): 1. Our work on gene-environment interactions in the UKBiobank is up at the American Journal of Human Genetics 2. Our work on modeling ancient human population size history is up at Molecular Biology and Evolution

Botany valentine. Another from years past. New one on Monday!

The consequences of polyploidy are... well, complicated. A deep dive into polyploidy in a massively successful tribe of grasses. A masterpiece led by Michelle Stitzer, representing the work of a lot of folks on the PanAnd project over last 7 years. www.biorxiv.org/content/10.1...

The outer ear is a mammalian innovation but where did it come from? In our study in Nature, Mathi Thiruppathy and colleagues find that the outer ear arose from modification of an ancestral gill program first originating in marine invertebrates. www.nature.com/articles/s41... 1/n

There's a super fun story about these spurless Columbines! Pollinators mainly visit flowers for nectar, but these nectarless populations were very stable, and this study found both molecular & biological basis for these supposedly disadvantageous forms. 🧪 Link: www.sciencedirect.com/science/arti...

Happy to share our preprint on our favourite polyploid hybrid, Arabidopsis suecica. We examine the evolutionary cycle of polyploidy in this young allotetraploid, focusing on three key parts of the cycle: origin, meiotic adaptation and rediploidization
