Gene duplication, horizontal gene transfer, and trait trade-offs drive evolution of postfire resource acquisition in pyrophilous fungi

Proceedings of the National Academy of Sciences, Volume 123, Issue 1, January 2026. <br/>SignificanceWildfires affect large tracts of the terrestrial biosphere, and while much is understood about plant adaptations to fire, here we uncovered genomic adaptations in fungi that can be modeled to predict impacts on global C and N cycling. We …
