Researchers at the University of California, Riverside collected fungi from seven wildfire burn sites across California over five years. They sequenced fungal genomes and tested some fungal isolates with charcoal to see how they respond to burned material.
The study found both genetic and physical ways fungi survive and use charcoal. Some fungi copy genes to make enzymes that digest char. Others mix genes by mating. Some form heat-resistant structures underground and others grow fast when competitors are gone. These abilities could be useful to clean polluted soil or help restore burned landscapes.
