Alphaproteobacteria is a class of bacteria in the phylum Pseudomonadota (formerly "Proteobacteria"). [4] The Magnetococcales and Mariprofundales are considered basal or sister to the Alphaproteobacteria. [5] [6] The Alphaproteobacteria are highly diverse and possess few commonalities, but nevertheless share a common ancestor.

Proteobacteria adalah salah satu filum bakteri. Anggotanya mencakup berbagai bakteri patogen ternama, seperti Escherichia, Salmonella, Vibrio, dan Helicobacter, [1] serta bakteri yang sanggup ber simbiosis untuk menyemat nitrogen dari udara dan meng oksidasinya menjadi nitrat. Berbagai bakteri bintil akar tumbuhan legum merupakan anggota filum ini.

Feb 21, 2019 · Previous multi-gene tree studies of the Alphaproteobacteria were compromised by at least one of these problems, namely, simpler or less realistic evolutionary models (because they were not available at the time; for example, Williams et al., 2007 used the simple WAG+Γ4 model that cannot account for compositional heterogeneity across sites ...

Feb 25, 2019 · Compositional heterogeneity in the Alphaproteobacteria is a major factor that confounds phylogenetic inference. There are great disparities in the genome G + C% content and amino acid compositions of the Rickettsiales, Pelagibacterales (including alphaproteobacterium HIMB59) and Holosporales with all other alphaproteobacteria.
