What this entity is
Canonical name: Pseudomonadota. 1
Known alias: Proteobacteria. 1
Stable external identifier: No stable external identifier was reported in the source document. 1
Pseudomonadota is a bacterial phylum analyzed in the Lanthanide Methylotrophy Atlas — Summary using GTDB-r214 taxonomy and pangenome functional-marker data. 1
Findings across functional markers
Pseudomonadota contains 2,988 genomes with xoxF calls and 171 genomes with mxaF calls among 117,619 genomes. 1
The xoxF rate in Pseudomonadota is 2.5%, and the xoxF:mxaF ratio is 17.5:1. 1
These results support the atlas-wide finding that xoxF is more frequently detected than mxaF across the pangenome, while the source cautions that annotation-based detection does not establish enzyme activity or methylotrophic physiology. 1
Within Pseudomonadota, Pseudomonadaceae contributes 566 xoxF genomes and 1 mxaF genome. 1
Beijerinckiaceae contains 171 xoxF genomes among 508 genomes, corresponding to a 33.7% xoxF rate. 1
Hyphomicrobiaceae contains 33 xoxF genomes among 56 genomes, corresponding to a 58.9% xoxF rate. 1
The distribution of xoxF across Pseudomonadota contributes to the report’s hypothesis that lanthanide-dependent methanol oxidation extends beyond classical methylotroph lineages, although this interpretation remains based on marker detection rather than direct physiological measurements. 1
The PHB study refines this marker-based profile: Pseudomonadota had the highest reported PHB prevalence, with phaC in 60.9% of species (4,544/7,456), and accounted for 74.9% of all 6,067 phaC-carrying species. 2 This distribution supports the study’s finding that PHB pathways are strongly concentrated in particular clades, while the study’s environmental-selection and horizontal-transfer interpretations remain broader hypotheses requiring phylogenetically explicit validation. 2
