Abstract

Hyphomonas neptunium is a marine prosthecate alpha-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.
