The order Sphingomonadales, containing the families Erythrobacteraceae and Sphingomonadaceae, is a relatively less well-studied phylogenetic branch within the class Alphaproteobacteria. Prophage elements are present in most bacterial genomes and are important determinants of adaptive evolution. An “intact” prophage was predicted within the genome of Sphingomonas hengshuiensis strain WHSC-8 and was designated Prophage IWHSC-8. Loci homologous to the region containing the first 22 open reading frames (ORFs) of Prophage IWHSC-8 were discovered among the genomes of numerous Sphingomonadales. In 17 genomes, the homologous loci were co-located with an ORF encoding a putative superoxide dismutase. Several other lines of molecular evidence implied that these homologous loci represent an ancient temperate bacteriophage integration, and this horizontal transfer event pre-dated niche-based speciation within the order Sphingomonadales. The “stabilization” of prophages in the genomes of their hosts is an indicator of “fitness” conferred by these elements and natural selection. Among the various ORFs predicted within the conserved prophages, an ORF encoding a putative proline-rich outer membrane protein A was consistently present among the genomes of many Sphingomonadales. Furthermore, the conserved prophages in six Sphingomonas sp. contained an ORF encoding a putative spermidine synthase. It is possible that one or more of these ORFs bestow selective fitness, and thus the prophages continue to be vertically transferred within the host strains. Although conserved prophages have been identified previously among closely related genera and species, this is the first systematic and detailed description of orthologous prophages at the level of an order that contains two diverse families and many pigmented species.
