Our new preprint is out! 🍄 Decoupled evolution of antimicrobial repertoires in lichen-forming fungi We compared many lichen-forming fungal genomes to ask how different photobiont associations relate to their antimicrobial repertoires.

Overall, AMP repertoire size is conserved, but its composition is highly variable. CAZyme and BGC repertoires show stronger differences between photobiont associations. Different molecular repertoires may be shaped by different evolutionary constraints. Preprint: www.biorxiv.org/content/10.6... 🍄

6/ Looking back, the 2014 S. pennellii genome was only the beginning. The first map showed us that TEs mattered. The new assemblies show us how those elements shaped genome structure, gene neighborhoods, and recombination landscapes and a decade later, we can still learn new things

5/ In S. pennellii, these IPT genes are particularly enriched in regions containing Tekay elements, including complex clusters on chromosomes 8 and 11. A burst of transposable element activity may have helped reshape these genomic regions …. and may influence recombination

2/ Indeed back in 2014, www.nature.com/articles/ng...., we saw evidence that transposable elements had contributed to its evolutionary history. The 2014 genome was already telling us that “junk DNA” was not necessarily junk as many of them were inserted close to stress genes.
