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...

✨ Latest exciting story of the group in @nature.com. Here, we go beyond SNPs and built a species-wide atlas of genetic variants in yeast. With >1,000 near T2T genomes, we show how large genomic variations affect trait diversity. www.nature.com/articles/s41...

The #Drosophila Dscam1 gene generates 10000s of isoforms, but only a small fraction supports neuronal functions. This study shows that #fitness & #immunity are the likely primary evolutionary drivers of Dscam1 isoform diversity in #arthropods @plosbiology.org 🧪 plos.io/4gp8cWd

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

"We show that unrelated proteins have a universal tendency towards convergent evolution of secondary and tertiary motifs, causing an excess of high-scoring FP alignment... previous methods routinely overestimate significance by up to six orders of magnitude." www.biorxiv.org/content/10.1...

New paper out! 🎉 With an innovative approach of CRISPRing a gene mutation on many backgrounds, we provide a proof of concept for how “pan-genetic” analysis can reveal the true extent of genetic networks in a species. Thanks @plantevolution.bsky.social-lab! Open-access: tinyurl.com/3aw7t6ff

With the publication of a new preprint (www.biorxiv.org/content/10.1...) with collaborators @labschneeberger.bsky.social @plantevolution.bsky.social and @jurriaanton.bsky.social, I feel it is timely to talk about what will probably be the most successful 'failed' experiment of my career.

A ridiculous amount of very careful work by @jahemker.bsky.social and coauthors gave a clear answer - one needs ultra-long and not just long reads to call SVs correctly in Drosophila. Now we are ready to quantify evolutionary impact of Drosophila SVs. Let us know what you think!
