Phylogeny Dec 2017

I have updated the page massively today, including the taxonomy and systematics, bringing in the latest studies, and in the process I have removed the little cladogram (which was very good) as it was woefully out of date - if someone wants to do a new one, since it IS useful, it should include all of the classes of the "Proteobacteria" - Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Acidithiobacillia, Hydrogenophilalia, Oligoflexia and Deltaproteobacteria - the Epsilonproteobacteria have been moved to another phylum. The four orders of the Betaproteobacteria should be shown as per the article and refs linked - note that neighbour-joining algorithms aren't precise enough to show the relationships properly - maximum likelihood analyses of the whole phylum at 16S and ribosomal protein levels were used to determine the classes and orders of this class in particular - NB: the LPSN is over 10 months out of date now so you need to go by the current literature as the LPSN can't be relied upon for recent material (and it's not an official source anyway, just a convenience tool).

The page features an illustration under the heading beta-proteobacteria with a legend-button saying Rickettsia leading to a page by the same name placing Rickettsia among alpha-proteobacteria. Ugly (and wrong). 62.202.12.176 (talk) 12:09, 8 December 2011 (UTC)

You are right. Rickettsia is not a betaproteobacteria but an alphaproteobacteria. The image should be removed.--Miguelferig (talk) 17:08, 29 June 2012 (UTC)

The picture is still there. Siegele (talk) 15:34, 9 October 2012 (UTC)

Noticed it as well, please remove the picture.

Phylogeny

Hey all! I removed the giant cladogram that was the phylogeny section and am moving it here because it seemed to be a bit impenetrable for a regular reader. If anyone disagrees or is interested in reworking it to make it more clear I'd be happy to talk about it! In the meantime, I slapped together a simplified diagram of the more important phylogenetic relationships and added it to the page. Suggestions are most welcome!

Six, not eight classes of Pseudomonadota

This article twice says that the phylum Pseudomonadota has eight classes. I think the old Proteobacteria used to have eight, but the change in name came with major reorganization, and there are only six classes now. But I found this out in Wikipedia, and I don't feel qualified to make the changes. I'm not a microbiologist; I just fix things. Uporządnicki (talk) 23:47, 16 April 2022 (UTC)

Seven, not four orders?

In October 2019, an IP User added three more orders to the four that were already listed in the taxobox. But the text still speaks of "the four" orders. Uporządnicki (talk) 12:50, 18 April 2022 (UTC)
