  • Great book! I'm on the second week and seeing definite improvement on my yeast infection symptoms. I must also note that the texture of my skin became very soft and consistent. I completely agree with many of your arguments in the book especially those about conventional methods for treating Yeast Infection. I wanted to let you know that I feel so fine you have no idea. I am not so tired all the time and I feel very energetic. The rashes on my neck and on the right side of my nose have also cleared up. I wish you all the health and happiness in the world and thanks so much for helping me. I really appreciate your time and efforts to assist me. ●●●

  13. 13. TIGRTIGRTIGRTIGR “Nothing in biology makes sense except in the light of evolution.” T. H. Dobzhansky (1973)
  14. 14. TIGRTIGR Evolution and Genomics Overlap • Genome sequences contain a record of the evolution of a species and all its genes • Evolutionary analysis is the key to interpreting genome sequences and making the most use out of them
  15. 15. TIGRTIGR Phylogenomics? Evolutionary information improves genome analysis -Classification of multigene families -Predicting functions -Origins of genes and pathways Genomics information improves evolutionary reconstructions -More sequences of genes -Unbiased sampling -Presence/absence needed to infer certain events Feedback loop between two types of analysis TIGRTIGR
  16. 16. TIGRTIGR
  17. 17. TIGRTIGR Why Completeness is Important • Improves characterization of genome features – Gene order, replication origins • Better comparative genomics – Genome duplications, inversions • Determination of presence and absence of particular genes and features is less subjective • Missing sequence might be important (e.g., centromere) • Allows researchers to focus on biology not sequencing • Facilitates large scale correlation studies • Controls for contamination
  18. 18. TIGRTIGR Uses of Phylogenomics • Species evolution and systematics • Lateral versus vertical evolution • Gene function • Gene and genome duplications • Genome rearrangements

Species Evolution I: Selecting Genome Projects to Increase Phylogenetic Diversity
  20. 20. TIGRTIGR Species EvolutionI I: Major Evolutionary Transitions • Analysis of S. pombe genome (Wood et al 2002) • Compared the genomes of eukaryotes to those of prokaryotes • Asked: “Are there genes in all eukaryotes with no obvious homologs in any prokaryote?” • Found ~200 genes which included many with know major roles in “eukaryotic” features like the cytoskeleton and chromatin as well as many with no known function
  21. 21. TIGRTIGR Bacteria Archaea Eukaryotes Giardia Trichomonas Naegleria Trypanosoma Euglena Plasmodium Tetrahymena Phytophthora Arabidopsis Chlamydomonas Dictyostelium Humans Fly Worm Encephalatozoon S. cerevisiae S. pombe Evolutionary Scenario
  22. 22. TIGRTIGR Evolutionary Transitions II: Single- vs. Multi-Cellularity • Analysis of S. pombe genome (Wood et al. 2002) • Compared multi-cellular vs. single-cellular species • Asked “Are there genes in all multi-cellular and not in any single-cellular?” • Found only 3 • Concluded that the multicellularity was likely the result of gene regulatory processes

  24. 24. TIGRTIGR Species Evolution III: Uncultured Microbes • Vast majority of microbes have never been cultured • Usually studied indirectly by cloning rRNA genes and using position within rRNA tree to predict biology • These predictions are frequently inaccurate
  25. 25. TIGRTIGR Genomics does not require initial culturing step. • Isolate, by filtration, all bacteria in a water sample • Extract total DNA in very large pieces • Clone those pieces as BACs into E.coli to get enough. • Sequence the BACs like a bacterial genome. Natural Water Filter concentrate Extract DNA Clone Into BACs Sequence Gene List

  29. 29. TIGRTIGR Vertical Inheritance From C. Darwin, origin of species, via W. F. Doolittle
  30. 30. TIGRTIGR Examples of Horizontal Transfers • Antibiotic resistance genes • Insertion sequences • Agrobacterium Ti plasmid • Toxin degradation genes on plasmids • Virus and phage gene acquisition and transfer • Organelle to nucleus transfers
  31. 31. TIGRTIGR Why Gene Transfers Are Useful to Identify • Laterally transferred genes frequently involved in environmental adaptations and/or pathogenicity • Identification of vectors of gene transfer (e.g., transposons, integrons, phage) • Identify species associations in the environment (e.g., Thermotoga and Archaea, Nelson et al.) • Identify organelle derived genomes in eukaryotic genomes
  32. 32. TIGRTIGR A Blast Search Does not Equal an Evolutionary Study
  33. 33. TIGRTIGR • Claim – “Hundreds of human genes appear likely to have resulted from horizontal transfer from bacteria at some point in the vertebrate lineage.” • Evidence – Genes match bacteria but not non-vertebrate eukaryotes – Or genes have stronger match to bacteria than to non-vertebrates

  51. 51. TIGRTIGR Predicting Function • Identification of motifs – Short regions of sequence similarity that are indicative of general activity – e.g., ATP binding • Homology/similarity based methods – Gene sequence is searched against a databases of other sequences – If significant similar genes are found, their functional information is used • Problem – Genes frequently have similarity to hundreds of motifs and multiple genes, not all with the same function TIGRTIGR

  55. 55. TIGRTIGR H. pylori and MutS • Prior to this genome, all species that encoded a MutS homolog also encoded a MutL homolog • Experimental studies have shown MutS and MutL always work together in mismatch repair • Problem: what do we conclude about H. pylori mismatch repair

  70. 70. TIGRTIGR Problems with Similarity Based Functional Prediction • Prone to database error propagation. • Cannot identify orthologous groups reliably. • Perform poorly in cases of evolutionary rate variation and non-hierarchical trees (similarity will not reflect evolutionary relationships in these cases) • May be misled by modular proteins or large insertion/deletion events. • Are not set up to deal with expanding data sets.

  75. 75. TIGRTIGR Types of Molecular Homology • Homologs: genes that are descended from a common ancestor (e.g., all globins) • Orthologs: homologs that have diverged after speciation events (e.g., human and chimp β-globins) • Paralogs: homologs that have diverged after gene duplication events (e.g., α and β globin). • Xenologs: homologs that have diverged after lateral transfer events • Positional homology: common ancestry of specific amino acid or nucleotide positions in different genes
  76. 76. TIGRTIGR Caution: Homology Based Predictions Have Many Flaws • Not all orthologs have the same function • Homology cannot be used to characterize novel pathways (e.g., D. radiodurans) • Absence of genes can be important to phenotypes (e.g., pathogenicity)

  94. 94. TIGRTIGR Uses of Phylogenomics • Species evolution and systematics • Lateral versus vertical evolution • Gene function • Gene and genome duplications • Genome rearrangements
  95. 95. TIGRTIGR Why Duplications Are Useful to Identify • Allows division into orthologs and paralogs • Improves functional predictions • Helps identify mechanisms of duplication • Can be used to study mutation processes in different parts of a genome • Lineage specific duplications may be indicative of species’ specific adaptations
  96. 96. TIGRTIGR Levels of Paralogy Within A Genome • All – All members of a gene family are linked together • Top matches – Only top matching pairs are linked together. Therefore, if in a large gene family, only the pair from the most recent duplication event is included • Recent – Operational definition based on comparison to other species. Only pairs which are more similar to each other than to selected other species are included.
