Yesterday, our team ran the Blodomloppet in Stockholm, to help draw attention to the importance of blood donation. We all ran 5 or 10 kilometers, we all made it to the finish, and got to recharge with a picnic! #blodomloppet

One more piece of work from Lore’s PhD-thesis is published! Here, she presents chromosome-level assemblies of the remaining species of the Podospora species complex - and make an attempt to resolve their phylogenetic relationships. Go, Podo, go! academic.oup.com/gbe/advance…

High-Quality Genome Assemblies of 4 Members of the Podospora anserina Species Complex

Abstract. The filamentous fungus Podospora anserina is a model organism used extensively in the study of molecular biology, senescence, prion biology, meio

Yes, we work on fungi… but, one or two of those prokaryotes also gets in! Here is a study on Microcoleus, together with our friends from Czech @dvorikus published in Nature communications. Check it out and read about barriers to gene flow in a microbe! link.springer.com/article/10…

The global speciation continuum of the cyanobacterium Microcoleus

Nature Communications - The relative importance of the various mechanisms that can drive microbial speciation is poorly understood. Here, Stanojković et al. explore the diversification of the...

Marieke van der Poel came from Utrecht to is join us for an internship. She got her own lab T-shirt 😊 and will let the (spore-) killers go alive again by picking up the work on meiotic drive in Neurospora! Thanks for joining us!

Alert: the first chapter of Ivar’s PhD is out! Here we can learn about how crapaud (a TE in Podospora... i.e., not a frog!) evolves. Great work, @Iv_wster, we look forward to more TE and RIP-stuff from you. mobilednajournal.biomedcentr…

Trying to avoid sideprojects, but …. now, lab-grown mycelia of the local Morchella importuna is back into the ground, together with quicklime and other good stuff. High risk (of freezing), but high gain (if it works!). Excited to see what comes up next year!!

Our paper on spore formation in Morchella galilaea, is published online in Frontiers in Microbiology. @XiHui_Du shows intriguing data on variability in ascospore size, number and shape and conidia produced directly from ascospores in this species! frontiersin.org/articles/10.…

Just back from Szeged, and a visit to the @laszlognagy group. We had a blast, hearing about all the interesting ongoing projects, shared ours and planned collaborative work on inheritance in basidiomycetes. And some great food and drinks, too! Thanks so much for hosting us!

Hmmm, why do fairy rings grow outwards?! Boel shows her three supervisors how to dig and move around parts of rings - to figure this out! Stay tuned (a couple of years) to see where the fungi goes 😅
