By restoring a fungal specimen that was shockingly described and preserved by the "father of modern taxonomy" Carl Linnaeus a quarter of a thousand years ago, this study echoes history and highlights modern research projects The untapped potential of Chinese museum collections
For centuries, the "desert coprinus" fungus Podaxis has attracted scientists and explorers, but relatively little research has been done on this genus
The study found that fungal spores can grow after 2-5 years in the museum, so the researchers tested the limits of fungal resurrection
-"It is incredible to let these fungi grow in our laboratory.
The researchers used these specimens to ask whether the free-living Podaxis species that grows in the desert is genomically and physiologically different from the species that grows on termite mounds
"These findings indicate that Podaxis living with termites is experiencing a relaxed selection pressure and a potential protection from competition and exposure to environmental stressors," said corresponding author Michael Poulsen
Podaxis growing on a termite mound
-"Although Podaxis living in the obligatory association with termites showed a loose choice, we also found that some Podaxis can either live on termite mounds or live freely in the desert
The museum has a large collection of knowledge resources, and we should work hard to ensure that these specimens can be used to answer important questions in science in the future
