This episode: Prions in yeast can allow better adaptation to changing conditions! Download Episode (9.5 MB, 13.9 minutes) Show notes: Microbe of the episode: Hepatovirus F News item Takeaways Prions can be deadly. They're misshapen proteins that cause a cascade of misfolding of similar proteins if they get into the nervous system, resulting in neurodegeneration in mammals. But in other organisms, they are not always so scary; some fungi use prions to regulate their behavior in varying conditions. In this study, a prion allows yeast to switch between a fast-growing lifestyle with shorter reproductive lifespan that can be beneficial in conditions where nutrients are often plentiful, and a slower-growing but more enduring lifestyle that helps in more scarce conditions.
