5. Questions : Differences in the environmental parameters  microbial community composition? Dominant populations? Functional variations ? Abundance profile differences?

6. Community similarity based on genus count Compare Genome  Genome Clustering  Genus, Hierarchical Clustering / PCA

7. 10 m 130 m 770 m 4,000 m Phylogenetic Distribution Compare Genome  PhyloDist  Metagenomes vs Genomes  Gene Count (60+) Virus

8. 10 m 130 m 770 m 4,000 m Phylogenetic Distribution Compare Genome  PhyloDist  Metagenomes vs Genomes  Gene Count (60+) Cren Eury Nano

9. 10 m 130 m 770 m 4,000 m CyanoProteoActinoBacteroidetes Phylogenetic Distribution Compare Genome  PhyloDist  Metagenomes vs Genomes  Gene Count (60+) VerrucoPlanctomycFirmic Chloroflex

10. Upper (10 m) Chloro Max. (130 m) Abyss (4,000 m) Phylogenetic Distribution Compare Genome  PhyloDist  Radial Tree  Customize (Phyla) / Bar

11. Gene of interest Find Genes  Gene Search  “rhodopsin”

12. Gene of interest Find Genes  Gene Search  “nitrogenase” * ?

13. Function Profile Find Function  COG Browser  Click "Flagellum structure and biogenesis"  Search All  Add Selected to Function Cart  Compare Genomes  Function Profile  View Function vs. Genomes  Search Name for "type" *

14. Function Profile Find Function  COG  COG Browser  “Cell Motility”  Search COG Name “Type”  Select all / Add to Function Cart  Compare genomes  Function Profile View Functions vs. Genomes  Filter “Flagellar” * *

15. Function Profile Find Gene  Gene Search “Transposase”

16. Conclusion : Differences in the environmental parameters  microbial community composition? Light (rhodopsin) Nutrients (nitrogenase) Dominant populations? Proteobacteria Functional variations? Flagellar proteins – no pattern Transposase – abundant at depth Abundance profile differences? Cyanobacteria
