MM52A:
Fungi in the Marine Environment eLightning

Session ID#: 76592

Session Description:
Fungi are globally distributed in the marine environment and inhabit diverse environments from sea ice to the deep biosphere. Within these environments, fungi interface a wide range of lifestyles, e.g. top-down control on phytoplankton (parasitism), organic matter recycling (saprophytism). Marine fungi also harbor a rich potential for natural product discovery, with >300 novel marine fungal natural products described annually, or for bioremediation processes of recalcitrant pollutants. Secondary metabolisms of marine fungi generate nitrous oxide which is a strong greenhouse gas and ozone-depleting agent. Nevertheless, marine fungi have been largely overlooked compared to their terrestrial counterparts and compared to other members of marine microbial communities. Little is known about their diversity, ecology, and their contribution to global biogeochemical cycles. In this session, we aim to bring together microbial ecologists, cell biologists, bioinformaticians, geochemists, and all other scientists who are interested in advancing our understanding of novel roles played by marine fungi in the marine environment and/or their application for biotechnology. Interdisciplinary studies using innovative culturing, ‘omics’ approaches, isotope techniques, and novel bioinformatics methodologies are particularly welcome.
