Bacterial immune proteins have repeatedly evolved to become parts of eukaryotic immunity. But how? Our new preprint uncovers a recent horizontal transfer event & shows how eukaryotes co-opted a toxic bacterial immune protein 🦠🧪🧵 1/

Ancestral sequence reconstruction analysis indicates the S1/S2 insertion in the SARS-CoV-2 spike gene likely interrupted a codon
Abstract. The genome of the seasonal acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has a 12-nucleotide insertion that produced a furin cleava

Best practices for improving alignment and variant calling on human sex chromosomes
Aligning and calling variants in a way that accounts for the sex chromosome complement of the sample will reduce false-positive variants and increase true-positive variants on the X and Y chromosomes.

Pregnancy loss is common in humans, and chromosomal abnormalities are the leading cause. Using genetic data from ~140,000 IVF embryos, we show that maternal variation in meiosis genes influences recombination and aneuploidy risk. First authors: @saracarioscia.bsky.social & @aabiddanda.github.io

Analysis of data from pre-implantation genetic testing sheds light on the genetic basis of meiotic-origin aneuploidy, the leading cause of human pregnancy loss, identifying common genetic variants ass...

Happy to share the final story from my thesis, demonstrating that the common ancestor of all terrestrial fungi had zymocin-like killer plasmids, a toxin system found in some budding yeasts. Come with me on an all-too-familiar, database dumpster-diving journey (1/10) www.biorxiv.org/content/10.1...

Zymocin-like killer plasmids were present in the common ancestor of terrestrial fungi
Some budding yeasts secrete killer toxins made by linear dsDNA plasmids located in the cytosol. The best-known example is the Kluyveromyces lactis toxin zymocin, which is encoded by a 9-kb killer plas...

✨ 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...

Kamilla Laidlaw, Hatwan Nadir, Chris MacDonald @yorkyeast.bsky.social and team @biologyatyork.bsky.social discover that killer toxin K28 resistance in yeast relies on COG complex-mediated trafficking of Ktd1. journals.biologists.com/jcs/article/... Article: journals.biologists.com/jcs/article/...
Microscopy images showing that correct localisation of either Ktd1 or Snc1 requires the COG complex.

New paper from my lab! We describe our idea that high-throughput pooled experimental methods – typically used to test thousands of hypotheses at once – also have huge potential to help in “everyday” experiments testing one or a few focused hypotheses. Why? Two reasons: doi.org/10.1093/g3jo...
