purpose of presentation
Purpose of Presentation
  • Introduce importance of environmental genomics to Canada
  • Outline how Canadian federal government and selected universities are organizing themselves in support of environmental genomics research and development
  • Identify some research elements of the current opportunity / challenge agenda for selected environmental genomics research activities
  • Introduce evolving North American / International efforts at environmental genomics research capacity building
  • Set the stage for discussion with you on how we can collaborate more fulsomely on complementary future environmental genomics research initiatives
what is environmental genomics
What is Environmental Genomics?
  • Environmental Genomics (EG)bridges the gap between genetics, physiology, and ecology
  • It involves utilization of a broad range of modern molecular techniques such as gene arrays and single nucleotide polymorphism (SNP) screens to monitor variation in gene structure and expression
  • EG can pinpoint potentially novel interactions between environmental stressors and expression of specific human, animal and plant genes
what is environmental genomics4
What is Environmental Genomics?
  • Applies knowledge gained on gene identification, structure and expression to environmental protection & management:
    • Can rapidly identify species in complex environments
    • Can indicate how environmental stressors affect gene expression in humans, animals & plants
    • Can demonstrate deleterious effects at molecular level before organism-level effects are shown
importance of environmental genomics i
Importance of Environmental Genomics (I)
  • Genomics builds upon and enhances traditional approaches to environmental toxicology determination
  • Genomics provides an understanding of organisms and biological systems that is a prerequisite for understanding environmental change
  • A key objective for environmental science is improved understanding, identification, and prevention of environmental problems
  • The behaviour and response of an organism / groups of organisms to environmental stressors is ultimately controlled by genes and the products they encode
importance of environmental genomics ii
Importance of Environmental Genomics (II)
  • Genomics can provide the next generation tools to help protect and manage the environment:
    • Environmental remediation & restoration (e.g. plants that can clean up contaminated sites)
    • Pollution abatement, prevention & detection (e.g. identification of soil / water pathogens, toxicants)
    • Wildlife management & conservation biology techniques (e.g. genetic ‘barcoding’ for species identification)
    • High throughput analysis and identification of soil / freshwater / marine microbial community
importance of environmental genomics iii
Importance of Environmental Genomics (III)
  • Genomics could be critical to examining biotechnology’s potential impacts on the environment, such as:
    • Unintended properties of genetically modified organisms (toxicity, allergenicity)
    • Emergence of invasive species
    • Displacement of native species
    • Spread of new ‘pest’ species
    • Gene transfer occurrence and mechanisms from genetically modified organisms to other organisms
why environmental genomics and why now
Why Environmental Genomics and Why Now?
  • “In the environment, virtually all microorganisms exist in complex communities whose function as a whole is far greater than the sum of what their individual members can achieve.. Understanding these interactions – the ways in which microorganisms work together to achieve complex tasks – will provide insights that can be used to address global challenges of energy production, improved human and animal nutrition, understanding infectious disease mechanisms, and furthering environmental remediation and restoration”
  • Source Jay Short – President and CEO Diversa 2004
why environmental genomics and why now9
Why Environmental Genomics and Why Now?
  • “The growth and survival of microorganisms drives biogeochemical cycling of elements, detoxifies many organic compounds, sequesters many inorganic compounds, produces a wide range of valuable and renewable industrial compounds, makes essential nutrients present in the biomass of one generation available to the next generation, and maintains the conditions critical to all life on earth”

  • Risk Assessment / Management
    • Test Method Development
      • TheEnvironmental Technology Centre (ETC) is developing & standardizing genomic-based procedures to ensure more accurate data for submission under the New Substances Notifications Regulations.
    • Environmental Monitoring
      • The Pacific Environmental Science Centre (PESC) & National Wildlife Research Centre (NWRC) are using toxicogenomic techniques to link observed effects of toxics to specific environmental exposures & providing improved “early warning” signals to industry regulators.
  • Conservation Biology and Wildlife Management
    • The Canadian Wildlife Service (CWS) is developing and applying genetic markers towards the resolution of conservation issues.
  • Improved Enforcement & Compliance
    • The PESC has completed a Pulp and Paper study that positively identifies mill effluents that are causing endocrine disruptor effects to fish.
toxicogenomic applications
Toxicogenomic Applications
  • Environment Canada BC Labs have created internal capacity for all phases of genomic testing, with the exception of gene array spotting.
  • Focus to use EC existing aquatic toxicological methods as platform (Rainbow trout test fry and early stage test, new amphibian methods in works)
  • Application to chronic endpoint; traditional methods not sensitive enough to detect molecular level toxicity. Good predicator to “real world” effects
development of microarrays

synopsis of environmental genomics research experiences 1999 2005
Synopsis of Environmental Genomics Research Experiences 1999-2005:
  • Potential environmental impacts from applied genomics in agroforestry, fisheries, mining, and industry
  • Low prominence / priority ascribed to environmental genomics writ large until recently
  • Little recognition outside EC given to stewardship issues (regulatory, ethics, IP, biodiversity)
  • Increasing importance being ascribed to environmental genomics & “smart regulations”
  • Sub-critical masses of environmental genomics capacity across Canada
  • Limited current EC capacity in environmental genomics against all research areas
  • Evidence of tremendous interest for green genomics on the horizon and attendant funding mechanisms to support basic and applied R & D
