With regard to phylogenetic evidence, they were circumscribed as the phylum Bacteroidetes but they stay principally studied as independent clades due lack of phenotypic coherence. The phenotypes foremost attributed to Bacteroidetes are the ability to decompose complex organic matter, gliding motility and pigmentation with flexirubins and carotenoids.

For example, some saline environments seem to be selective of these bacteria out-competing other phyla. The goals of this doctoral thesis targets are 1 reviewing the taxonomy of the Bacteroidetes, 2 finding coding what is phylogeny and give example that could translate into an identifying phenotype and 3 finding what of their genes are selected in saline environments.

This new taxonomy, on top of naming a new phylum, three classes, what is phylogeny and give example orders, eight families and a genus all of them with standing in bacterial nomenclaturepaveda precise phylogenomic analysis of the Bacteroidetes, which on earlier studies included members ofthe new phylum Rhodothermaeota. However, it curtailed probabilities of finding salinity-relatedgenes, since most extreme halophiles belong to the new phylum. This secretion system is involvedin the gliding motility of some Bacteroidetes, but it is also an excreting route for hydrolyticenzymes.

The anaerobic lineage of the Bacteroidales can fulfill the aerobic respiration thanks what is absolute error class 11 physics a cytochrome bdoxidoreductase with high oxygen affinity that helps detoxifying their surroundings. Last, the genes of the respiratory Complex I are not arranged phylogenomically in the Bacteroidetes.

Moreover, we found evidences of this complex being invented by the Bacteroidetes and its horizontal transmission within saline environments. The simultaneous expression of the type-IX secretion system and the respiratory chain of the Bacteroidetes, which is adapted to the environments they live at, is likely responsible for the adaptive radiation of the phylum. Some of these genes are horizontally transferred, but all together they predict the original bacteroidete was a heterotroph aerobic decomposer of complex organicmatter, likely living in freshwater.

By contrast, if phylogenetic relatedness predicts the competitive ability of species, in the manner that closely related species can compete givf efficiently for the same resources 16then species will be more likely to coexist in low phylogenetic diversity scenarios. By contrast, high phylogenetic diversity responses could be associated with pbylogeny among species 3536but also with competition processes when competitive exclusion occurs between close relatives with patent niche overlap 1637 ,
