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/...
Turnover of retroelements and satellite DNA drives centromere reorganization over short evolutionary timescales in Drosophila
Centromeres reside in rapidly evolving, repeat-rich genomic regions, despite their essential function in chromosome segregation. This study of centromere evolution over short evolutionary timescales i...

What I am pretty sure is Porpidia crustulata, although it seems Porpidia is a difficult genus. All I can say is that I can find no reason for it not to be crustulata. Potential second county record. #lichensGB

Lichen on a Twig... On my walk today, I picked up some twigs blown on the ground by the wind and found them covered by Star Rosette Lichen (Physcia stellaris) with abundant apothecia and picnidia! What a beautiful thing on the ground! #Lichen #beauty #NaturePhotography

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

@tbadet.bsky.social and I have a preprint out on transposon silencing in fungi!
Genome size evolution is fascinating and showcases the dynamic nature of transposon activation.
What we understand less are the dynamics of transposon defense systems encoded by the genomes.

The two toxins—cytolethal distending toxin B (cdtB) and apoptosis inducing protein of 56kDa (aip56)—are implicated in a defensive endosymbiosis in aphids. Our lab found HGT of these genes to insects in multiple orders, where they function in anti-parasitoid defense (2/n): tinyurl.com/m9mufn9a
