  1. Cyber Metagenomics; Challenge to See The Unseen Majority in The Ocean Kayo Arima California Institute for Telecommunications and Information Technology (Calit2)-University of California, San Diego Division

  2. Looking Back Nearly 4 Billion YearsIn the Evolution of Microbe Genomics Eukaryote has the nuclei . Prokaryotes has genes but no nuclear membrane. Science Falkowski and Vargas 304 (5667): 58

  3. Evolution is the Principle of Biological Systems:Most of Evolutionary Time Was in the Microbial World You Are Here Much of Genome Work Has Occurred in Animals Source: Carl Woese, et al

  4. Two completely different approach to get microbial genomic information Source: Karin Remington J. Craig Venter Institute Microbial whole genomics Metagenomics Environmental sample Culture (grow) in lab Isolate the colony Culture the isolated colony DNA extraction Enz. digestion Shotgun sequencing Gene assembly Environmental sample DNA extraction Enz. digestion Shotgun sequencing Scaffold assembly

  5. Down Side of Metagenomics Often fragmentary Often highly divergent Rarely any known activity No chromosomal placement No organism of origin Ab initio ORF predictions Huge data

  6. Genomic Data Is Growing Rapidly, But Metagenomics Will Vastly Increase The Scale… 100 Billion Bases! 35,000 Structures Protein Data Bank GenBank www.rcsb.org/pdb/holdings.html www.ncbi.nlm.nih.gov/Genbank Total Data < 1TB

  7. Full Genome Sequencing is Exploding:Most Sequenced Genomes are Bacterial First Genome 1995 6 Genomes/ Year 2000 Ongoing Genomes Completed Genomes 90 Metagenomes Total 422 Total 1665 www.genomesonline.org

  8. Marine Metagenomics • Microbes account for more than 90% of ocean biomass, mediate all biochemical cycles in the oceans and are responsible for 98% of primary production in the sea. • Metagenomics is a breakthrough sequencing approach to examine the open-space microbial species without the need for isolation and lab cultivation of individual species.

  10. Marine Genome Sequencing ProjectMeasuring the Genetic Diversity of Ocean Microbes Sorcerer II Datafrom this area has already reach to 10% of GenBank. The Entire Data Will Double Number of Proteins in Embank!

  11. Sample Metadata from GOS • Site Metadata • Location (lat/long, water depth) • Site characterization (finite list of types plus “other”) • Site description (free text) • Country • Sampling Metadata • Sample collection date/time • Sampling depth • Conditions at time of sampling (e.g., stormy, surface temperature) • Sample physical/chemical measurements (T (oC), S (ppt), chl a (mg m-3), etc) • “author” • Experimental Parameters • Filter size • Insert size
