BiS2C: Lecture 9: Microbial Diversity
The document discusses a lecture on microbial diversity. It notes that the tree of life is mostly microbial, diverse methods exist to study microbial diversity, and most microbial diversity remains poorly characterized. Sequencing methods like rRNA and metagenomic sequencing have improved understanding of microbial phylogeny but much diversity remains unknown.

As with Leptospirillum group I, both Leptospirillum group II and III have the genes needed to fix carbon by means of the Calvin–Benson– Bassham cycle (using type II ribulose 1,5-bisphosphate carboxy- lase–oxygenase). All genomes recovered from the AMD system contain formate hydrogenlyase complexes. These, in combination with carbon monoxide dehydrogenase, may be used for carbon fixation via the reductive acetyl coenzyme A (acetyl-CoA) pathway by some, or all, organisms. Given the large number of ABC-type sugar and amino acid transporters encoded in the Ferroplasma type Figure 4 Cell metabolic cartoons constructed from the annotation of 2,180 ORFs identified in the Leptospirillum group II genome (63% with putative assigned function) and 1,931 ORFs in the Ferroplasma type II genome (58% with assigned function). The cell cartoons are shown within a biofilm that is attached to the surface of an acid mine drainage stream (viewed in cross-section). Tight coupling between ferrous iron oxidation, pyrite dissolution and acid generation is indicated. Rubisco, ribulose 1,5-bisphosphate carboxylase–oxygenase.

The threshold for groups (coloured wedges) was an average branch length of <0.65 substitutions per site. Notably, some well-accepted phyla become single groups and others are split into multiple distinct groups. We undertook this analysis to provide perspective on the structure of the tree, and do not propose the resulting groups to have special taxonomic status. The massive scale of diversity in the CPR and the large fraction of major lineages that lack isolated representatives (red dots) are apparent from this analysis. Bootstrap support values are indicated by circles on nodes—black for support of 85% and above, grey for support from 50 to 84%.

We undertook this analysis to provide perspective on the structure of the tree, and do not propose the resulting xonomic status.
