Nya upptäckter om svamparnas evolution - Kungl. Vetenskapsakademien Nya upptäckter om svamparnas evolution

Looking forward to give this open, and public, lecture tonight! Will be possible to see online later if you miss it today.

Highly recommended! Hanna’s team is doing ground-breaking research, Stockholm is a lovely city, and a Swedish PhD position is very attractive - an actual job with paid holidays, sick leave, parental leave and pension rights.

We have several open positions in my group, funded from the ERC Grant on the Early Sequestered Germline of Fungi. We search broadly for applicants at both PhD and master-level, with a dedicated interest in fungal evolutionary biology. Please forward and RT!

Early germline sequestration in a basidiomycete fungus In sexual organisms, inheritance of new mutations is highly dependent on the timing of germline definition. Here, we used the fairy ring–forming fungus Marasmius oreades to challenge the general assum...

It started as a master thesis project by Markus Hiltunen, and ended up in this publication in Science. What a fun project to work on! Thanks Markus - and all other coauthors, too, for a great team work! www.science.org/doi/10.1126/...

Thanks, Daniel! It is a fantastic opportunity to scale up the work. I will soon post adds for people joining the project, so mycologists - stay tuned!

Great to have you in joining the group, Gulya! 😀

Isolation and characterization of edible mushroom-forming fungi> from Swedish nature Fungi are a highly diverse group of organisms, of which only a small subset has been taken into cultivation for application in biotechnology and food industry. Accordingly, outside of a few model...

Our lab went out in the forest and helped our dedicated master student Mario to gather edible mushrooms for cultivation. Here is the end product! In particular proud of Hericium coralloides who fruited nicely for Mario in the lab! 😀 imafungus.pensoft.net/article/1422...

Evolution of a bipolar sexual compatibility system in Marasmius Sexual compatibility in the Basidiomycota is governed by genetic identity at one or two loci, resulting in compatibility systems called bipolar and tetrapolar. The loci are known as HD and P/R, enc...

Our paper on the evolution of a bipolar sexual compatibility system in Marasmius is out! We show that Marasmius obeys to the typical Agaricomycete way to evolve bipolarity from tetrapolarity - by loss of mating compatibility function of the P/R locus. doi.org/10.1080/0027...

Happy #worldsoilday !! Have you ever looked INTO soil ? If no, join us at Soilwatching: Windows to the #soil let us peek at all its inhabitants. If you know the channel already - stay tuned, there will soon be two new episodes:) www.youtube.com/@Soilwatching

JOB ALERT!
A fully funded PhD opportunity awaits at Uppsala University, Sweden, focusing on the evolution and biology of lichen photobionts.

The position will involved field work, molecular lab work and data analyses (from meta-omics to pop genetics).

Thanks for the really great talk, Rike!

Got to give a talk on a BIG screen today! 🤩 Thanks @loreament.bsky.social for the photo and the #Mycology Nordics conference for hosting!🧪🍄🍄‍🟫

Thanks @edithhammer.bsky.social‬ and everyone else who attended and made the meeting so awesome! Look forward to the next one 😀
