In the leadup to the ISME conference, which will take place in Lausanne (Switzerland) in August 2022 (https://isme18.isme-microbes.org), we will hold several hybrid events on Microbial Ecology. You’re invited to join the first UP-ISME session on Tuesday, March 8th, at 10 am. The event will be opened by ISME President Prof. Nicole Dubilier. The session will include talks by two prominent international speakers, Prof. Lynne Boddy (Cardiff University, UK) and Prof. Colin Murrell (University of East Anglia, UK). Please see details below (speaker profiles attached).
The event is open to everyone. Please indicate your preference for in person vs online attendance by completing the google form (https://forms.gle/FETpbH1WHSakUKvM7). Note that, due to capacity issues, in person attendance is restricted.
Fungus wars : antagonistic mycelial interaction
Lynne Boddy (Cardiff University, UK)
Fungi are rarely found growing alone in nature but usually in communities with other fungi, and also with bacteria and invertebrates. Since they are all competing for space and resources, antagonistic interactions are the norm – fungi fight each other! They ‘attack’ and ‘defend’ their territory in different ways: (1) antagonism at a distance; (2) hyphal interference; (3) mycoparasitism; and (4) gross mycelial interaction. They employ a chemical arsenal of enzymes, volatile and diffusible organic compounds. Aggressive interactions are often the main reason for changes in fungal communities, but increasing/decreasing stresses and disturbance have major roles too.
Ecology of isoprene degrading bacteria- a missing link in an important biogeochemical cycle
Colin Murrell, School of Environmental Sciences, University of East Anglia, Norwich, UK
Isoprene is a climate-active, organic compound that is released into the atmosphere in similar quantities to that of methane, making it one of the most abundant trace volatiles. Large amounts of isoprene, a climate active gas, are produced by trees but also by microbes, including algae in the marine environment. We have been studying bacteria that grow on isoprene using a soluble diiron centre monooxygenase which is similar to soluble methane monooxygenase. Our studies on the physiology, biochemistry and molecular biology of aerobic isoprene degrading bacteria have enabled us to develop molecular ecology tools to examine these bacteria in the environment. Functional gene probing, DNA-stable isotope probing, metagenomics, metatranscriptomics and metaproteomics experiments show that isoprene-degrading bacteria are widespread in soils, leaf surfaces and estuarine sediments and that they are likely to play a major role in the metabolism of isoprene before it escapes to the atmosphere.
UP - ISME Speakers
Lynne Boddy is Professor of Fungal Ecology at Cardiff University UK. She has taught and researched into the ecology of fungiLynne Boddy is Professor of Fungal Ecology at Cardiff University UK. She has taught and researched into the ecology of fungi associated with trees and wood decomposition for 40 years. She is currently studying the fascinating communities of fungi and other organisms that rot the centres of old trees, the ash dieback fungus that is rampaging across the UK from Europe, the ways in which fungi fight each other and form communities, how they search the forest floor for food resources and respond to their finds, and how climate change is affecting fungi. She is a prolific author having co-authored “Fungal Decomposition of Wood” and “The Fungi”, her most recent (early 2021) being “Fungi and Trees: their Complex Relationships”, and the children’s book “Humongous Fungus”. She has edited six books, published over 300 scientific papers, and is chief editor of the journal Fungal Ecology. She was (2009–2010)president of the British Mycological Society. Lynne is an ardent communicator of the mysteries and importance of the amazing hidden kingdom of Fungi to the general public including TV, radio, popular talks, videos, articles and exhibitions. She was awarded an MBE in the Queen’s Birthday Honours list in 2019 for Services to Mycology and Science Outreach.
