Overview

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.

Project Participants

Margo Haygood

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.

Eric Schmidt

Associate Program 2 leader

Dr. Schmidt is a leader in marine natural products chemistry of bacterial symbionts. His group pioneered cloning, expression, and engineering of a secondary metabolite biosynthesis pathway of an uncultivated symbiont of a marine invertebrate. He brings strong expertise in marine natural products structural elucidation, combined with biochemistry and molecular biology of bacterial secondary metabolite production. Dr. Schmidt's research program has been funded primarily by the NIH. Dr. Schmidt will be responsible for leading chemical characterization of lead compounds from the screening program, including training Filipino researchers to become self-sufficient in using instrumentation provided by PharmaSeas. He will provide expertise in biosynthesis to all participants. He will lead AP2, investigating mollusk symbionts as sources of drug leads.

Baldomero Olivera

Participant, Associate Program 2

Dr. Olivera is an internationally recognized biochemist whose investigation of neuroactive peptides from cone snail venom is a classic example of elegant basic biomedical science linked to marine biotechnology. He brings expertise on central nervous system physiology and biochemistry together with deep knowledge and experience of marine biology research in the Philippines.

Dr. Olivera's research program has been funded primarily by the NIH. Dr. Olivera will lend his expertise in neurobiology to identifying central nervous system leads particularly to AP2.

University of Utah: The University of Utah is the leading Carnegie Research I University in the Intermountain West, and emphasizes interdisciplinary and interactive opportunities via the Huntsman Cancer Institute, the Pediatric Pharmacotherapy Program, the Brain Institute, and many departments in the School of Medicine, College of Engineering, and College of Pharmacy, where AP2 will be based. The College of Pharmacy recently ranked second in NIH support among colleges of pharmacy in the US after UCSF. This solid research base is backed by shared core facilities providing access via expert operators to the most advanced equipment in chemistry and biology, as described in Resources. In drug development, Utah features the NIH Anticonvulsant Drug Development Program, a large zebrafish core facility that is focused on drug screening and mechanism, and a mouse transgenic core facility based upon the research of recent Utah Nobelist M. Capecchi. An emphasis on graduate education has led to the creation of several cross-disciplinary training programs that bring more than 60 graduate students to the University per year, in addition to the usual department-centered direct admissions process. The shared core facilities and training programs reinforce the university emphasis on interaction between departments and colleges.

Gisela Concepcion

Associate Program 4 leader

Dr. Concepcion is a leading Filipino marine natural products chemist. Her focus has been on marine natural products from sponges and their associated microbes, contributing to discoveries of anti-cancer and anti-malarial marine natural products and leading to numerous publications and patents.

This study is designed to provide the most pertinent information to support conservation goals, while supporting the focused research of APs 2 and 3 and the broad sampling required to provide a diverse set of bacterial isolates for AP4 by providing mollusk identification, suitable molecular investigations, sample archiving and dissemination of results via appropriate databases. The main sampling area will be on a transect from Cebu City to Zamboanga. Sampling will focus on coral reefs, mangroves, seagrass beds and intertidal flats. AP1 will provide training in taxonomy and cooperate in outreach.

Associate Program 2: Bacterial symbionts of gastropod molluscs: cultivation, drug discovery, and neurological activity

Schmidt (leader), Olivera, Haygood, Concepcion, Rosenberg

AP2 will focus on microbes associated with gastropod molluscs. It will provide chemistry support to AP3 and 4. It will provide training opportunities in microbiology, neurophysiology, biochemistry and structural elucidation.

Associate Program 3: Microbes associated with shipworms (Teredinidae) as sources of drug leads and cellulolytic enzymes

Haygood (leader), Distel, Schmidt, Concepcion, Rosenberg

AP3 will build upon an existing collaboration between Haygood and Distel's groups and that of Carlos Soares, Federal University of Rio de Janeiro. It will focus on specific symbionts as well as other associated microbes of shipworms and other herbivorous molluscs, and will characterize both secondary metabolites and enzymes for converting biomass to biofuels. The research will include both proven and innovative cultivation methods and state-of-the-art cultivation-independent community analysis and sophisticated microscopy. It will provide cultivation, and microscopy support to AP2 andAP4. It will provide training opportunities in microbiology, molecular biology and microscopy.

Associate Program 4: Screening of mollusk isolates for biological activity and enzymes for biomass conversion.

Concepcion (leader), Olivera, Schmidt, Distel

AP4 will combine existing assets in antimicrobial and anti-cancer screening in the Philippines with neurological, cancer and cellulase screens available in the US participants laboratories with the ultimate goal of transferring most screening technology to the host country by the end of the project. AP4 will also take a lead role in data stewardship and technology transfer to the private sector. It will provide the screening for the broad-based cultivation effort in the Philippines as well as support the focused efforts of AP2 and 3. It will provide training opportunities in marine biotechnology and conservation outreach. We plan to develop biodiversity education for primary school children in areas of high marine biodiversity. The ICBG team will build upon this foundation to help teachers and their students to monitor key molluscan species in their area. We hope to encourage students to become emissaries for conservation through their involvement as "citizen scientists" in reporting the state of their local biodiversity.
