Can yeast help us fight fungal crop diseases?
Every year, fungal pathogens destroy more than 10% of the world’s major crops, threatening global food security, biodiversity, and farmers’ livelihoods. It’s a silent crisis that costs billions and fu...

So cool, a novel archaeon with a super small genome and no metabolic genes!

A cellular entity retaining only its replicative core: Hidden archaeal lineage with an ultra-reduced genome
Defining the minimal genetic requirements for cellular life remains a fundamental question in biology. Genomic exploration continually reveals novel microbial lineages, often exhibiting extreme genome...

This paper makes me CACKLE. Every so often a fungus comes along that is like "oh, you think you understand genetics? lol. You're cute." and completely upends everything we thought we knew.

Distribution of haploid chromosomes into separate nuclei in two pathogenic fungi
Nuclei define eukaryotes, enabling macromolecular compartmentalization and cellular regulation. Each nucleus is believed to contain one or more haploid sets of chromosomes (1N). However, we discovered...

Can we link satellite images and fungal community composition in the soil? Yes! How? Check this paper.
It was a pleasure to collaborate on this story. Big congrats to Mathies and all the co-authors.

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...

Out now! We consolidated >600 Dutch yeast and characterised their activity against spoilage yeasts and relevant human and plant pathogens, focusing on yeasts that secrete antifungal proteins. Great resource for biocontrol and beyond.
