Dr. Alfredo Justo, curator of botany and mycology at the New Brunswick Museum, unveils the mysterious world beneath our feet - the vast, largely undocumented kingdom of fungi. With backgrounds spanning Spain, the United States, and now Canada, Dr. Justo brings a wealth of expertise to our discussion about the cutting edge of fungal research.
Unlike plants and animals, fungi remain largely enigmatic because we rarely see the actual organisms themselves - only their fruiting bodies (mushrooms) that occasionally emerge. This fundamental challenge has left mycology decades behind other biological sciences. As Dr. Justo explains, studying fungi is like trying to understand plants by only examining their fruits, never seeing the plants themselves.
The conversation explores how DNA sequencing has revolutionized the field, allowing researchers to identify species with unprecedented accuracy. Through initiatives like the Fungal Diversity Survey (FunDIS) and MicroMap Atlantic Canada, scientists and citizen researchers are collaborating to document North America's fungal diversity. With over 70,000 mushroom specimens DNA barcoded so far, we're just beginning to understand the scope of fungal biodiversity.
Beyond taxonomy, we delve into fungi's remarkable potential applications. From mycorrhizal relationships that enhance forest health to bioremediation of contaminated soils, from pre-inoculated trees that produce edible mushrooms to promising medical compounds like those found in chaga and lion's mane, fungi offer solutions to some of our most pressing challenges.
