    What Fungi Reveal About Multicellular Life

    What Fungi Reveal About Multicellular Life

    How did multicellular life evolve? We don’t know! However, fungi are helping us develop ideas about the emergence of complex life. Today we are joined by Dr. William Ratcliff, who has successfully induced naturally unicellular yeast to evolve into multicellular ‘snowflake yeasts’ in his lab at Georgia Tech. Prepare for a delightful interview featuring evolutionary history, biotechnology, semantics, philosophy, and life itself.

    Dr. William Ratcliff has his Ph.D. in Ecology evolution and Behavior and runs the Ratcliff lab at Georgia Tech and is the Co-Director of the Interdisciplinary Graduate Program in Quantitative Biosciences.
    Topics covered:
    The difference between multicellular life and single cellular lifeWhat is an organism?Evolutionary trends and novelties in multicellular lifeCatalyzing multicellular life in vitro Why yeast— specifically saccharomyces cerevisiae — are so widely used in genomics research and biotechnologyThe Ratcliff Lab’s development of multicellular yeasts dubbed ‘snowflake yeast’Mechanistic basics of multicellular yeasts, particularly entanglementPrototaxites and its characteristics of entanglements Cellular differentiation and cellular suicide in evolving snowflake yeasts Reversing multicellular evolution  Cyanobacteria, Bangiomorpha pubescens and other early forms of multicellular life Ways that multicellularity can be expressedMyxococcus xanthusAcellular slime moldsHow to grow snowflake yeast at home!Show notes:

    Mushroom Chocolate

    Mushroom Chocolate

    Love chocolate? You have fungi to thank for that! On today's show we are walking you through the complex journey between the cocoa bean and a chocolate bar.  The unmatchable decadence is achieved by unique fermentation methods and microbes. Yeast, filamentous fungi, and bacteria are all at play and today we have a chocolate scientist and PhD candidate, Caitlin Clark, who has dedicated her research to chocolate fermentation.

    Topics Covered
    Lactic acid fermentation versus chocolates specialty microbesThe complex and ethical journey of chocolate makingAlkalizing chocolatePolyphenol content in a variety of chocolate productsPsychoactive properties in chocolate’s constituents such methylxanthine and theobromine How fermentation alters potency of these constituents Mycorrhizal, endophytic, and pathogenic fungi involved in the cacao trees Other fungal relationships such as endophytes and mycorrhizal species Microbiome of fermentation in cocoa including yeasts, filamentous geotrichum, bacillus bacteria and moreWild ferments, aseptic ferments and experiments with starter culturesChemical and mechanical ways that fungi transform the stockWhat determines a ‘good’ microbial presence versus a ‘bad’ one in the chocolate making processHow cocoa byproducts are madeBloom in chocolateHow to shop for the best quality chocolate

    Kew's Fungarium: The World's Largest Collection of Fungi

    Kew's Fungarium: The World's Largest Collection of Fungi

    Over one million specimens of fungi share a space known as the Fungarium at the Royal Botanic Gardens, Kew. It is the largest collection of dried fungi in the world with specimens as old as the 1700s.

    Today we welcome lead mycologist Tuula Niskanen, and Fungarium curator Lee Davies to spotlight this important collection. We discuss when, where, why, and how fungi from all over the world are collected, studied and preserved. 
    Topics Covered:
    How the Kew Fungarium is curated and maintained The value and importance of saving physical specimensShelf life and preservation methods of fungi in the form of spores, mycelium and fruiting bodiesSpecimen highlightsThe Kew Gardens State of the World’s Fungi ReportHow citizen science can help and benefit from Kew

    Mycoviruses: Fungi Can Get Sick, Too

    Mycoviruses: Fungi Can Get Sick, Too

    Today’s show covers a field known as mycovirology, or the study of viruses that infect fungi. This esoteric science is nascent but profound in its applications, and we are welcoming one of the few people in the world who are studying these relationships. Why do mycoviruses matter? How can we work with and against them? How can this subfield influence mycology as a whole?
    We welcome Dr. Brenda Wingfield from the university of Pretoria in South Africa. Brenda holds her degree in fungal genomics and has published over 300 respective articles. Her work has expanded the mycological fields of taxonomy, phylogeny, ecology and tree pathology. 
    Topics Covered:
    Defining mycovirology What makes fungal viruses unique from othersStuck fermentation caused by killer yeastsAsymptomatic vs symptomatic virusesMechanisms of viral infection in fungiUsing mycoviruses to combat Chestnut BlightViruses transferring from plants to fungiArmillaria virusesGenetic engineering with virusesWhat we know about the fungal immune systemThe detriment of La France disease in Agaricus bisporus farms 1000 Fungal Genome Project Show notes:

    Mycopesticides for Malaria Mosquitoes

    Zombie fungi aren't just cool — they're extremely useful.

    Dr. Brian Lovett is back on the show to discuss the powers of entomopathogenic fungi. We get into the weeds of what makes these fungi equip for success as carnivores, transgenic engineering, the evolution of pathology and more. Brian also shares cutting edge research from the MosquitoSphere in Burkina Faso, where he and his team work to combat malaria using Metarhizium fungi.

    Topics Covered:
    Defining entomopathogenic fungiChemical signaling and mechanisms of infectionCircadian rhythms in fungi, and how entomopathogenic fungi time keep in their hostsMycopesticides, especially to fight Malaria in mosquitoes Transgenic engineering of fungi with spider venom genes to target insects Metarhizium as a platform fungi for board and narrow range target specific Current practices, successes and challenges in the fight against malariaEthics of developing and deploying biotechnology in international local communities Synergies between bio and chemical insecticidesUnique chemical  compositions of entomopathogenic fungi
