Genomic analysis of Hyphomonas neptunium contradicts 16S rRNA gene-based phylogenetic analysis: implications for the taxonomy of the orders ‘Rhodobacterales’ and Caulobacterales Badger, Jonathan H. and Eisen, Jonathan A. and Ward, Naomi L.,, 55, 1021-1026 (2005), doi = https://doi.org/10.1099/ijs.0.63510-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Hyphomonas neptunium is a marine prosthecate α-proteobacterium currently classified as a member of the order ‘Rhodobacterales’. Although this classification is supported by 16S rRNA gene sequence phylogeny, 23S rRNA gene sequence analysis, concatenated ribosomal proteins, HSP70 and EF-Tu phylogenies all support classifying Hyphomonas neptunium as a member of the Caulobacterales instead. The possible reasons why the 16S rRNA gene sequence gives conflicting results in this case are also discussed., language=, type=
