The Philippine Mollusk Symbiont ICBG (PMS ICBG) project links a biodiversity survey of marine mollusks in one of the world's hotspots of diversity, with enzyme and drug discovery aimed at bacterial symbionts of mollusks. Mollusks constitute the most diverse marine eukaryotic group, occupying virtually every possible ecological niche. The diversity of microbes associated with mollusks is equally vast.
Within the mollusks, three particular groups exhibit what we believe to be the highest biotechnological and scientific potential: the bivalve family Teredinidae (genus Teredo) and the gastropod superfamilies Conoidea (genus Conus) and Muricoidea (genus Murex). The project directly addresses the goals of the ICBG program and will yield drug leads in central nervous system, cancer and antimicrobial areas, as well as strains and enzymes for cellulosic biofuels production. The project will characterize symbiotic diversity and pharmaceutical and biofuels potential of mollusk-associated bacteria in a comparative framework for the first time.
The plan focuses on training, conservation, and the development of drug discovery and biofuels programs within the Philippines. The Republic of the Philippines represents a unique nexus of exceptional biodiversity, dense human population with pressing societal and energy needs, consequent urgent conservation goals, and government and private sector commitment to education and technology to harness national human and natural resources for a sustainable future.
The project is led by Margo Haygood, marine microbiologist, University of Utah, in association with Gisela Concepcion, marine natural products chemist, Marine Science Institute, University of the Philippines, Baldomero Olivera, biochemist, and Eric Schmidt, natural products chemist and biochemist, both of University of Utah, Gary Rosenberg, evolutionary biologist, Academy of Natural Sciences, Philadelphia, and Daniel Distel, marine microbiologist, Ocean Genome Legacy.
Principal Investigator and Associate Program 3 leader
Dr. Haygood is a marine microbiologist by training, with 30 years of experience investigating marine bacterial symbioses. She is well known for her in-depth studies of marine invertebrate symbioses, particularly the association between the bryozoan Bugula neritina and its symbiont Endobugula sertula, which produces the anti-cancer bryostatins to protect the bryozoan's offspring from predation. Due in large part to the work of her group, this is now the best-understood example of a marine chemical defense symbiosis. Innovative use of laser-scanning confocal microscopy to characterize symbioses by localization of both symbionts and symbiotic compounds is a important recent contribution. She has led field expeditions in Japan, Honduras, Palau and Egypt, and has served on the board of directors of the Coral Reef Research Foundation, Palau.
Prior to her academic career, she was a program manager for the Office of Naval Research, where she managed extramural molecular biology and microbiology programs worth over 30 million dollars annually in current value, and received recognition for her management performance. The NIH, NSF, USDA, California and Oregon Sea Grant (NOAA) and the Office of Naval Research have funded her research program. As PI, Dr. Haygood will be responsible for the overall administration of the PMS ICBG including financial management, stewardship of data and resources, organizing communication and reporting, tracking of leads and ensuring compliance with legal requirements and broad standards of research and financial integrity. She will also lead AP 3, the OHSU/OGL/UU/UP collaboration investigating the potential of shipworm symbionts for discovery of drug leads and cellulolytic enzymes for biofuels production.
