Schematic representation of WO phage ORFs in the wPip, wMel and wSim genomes. (For each cluster, the accession number (http://www.sanger.ac.uk/Projects/W_pipientis/), the identifier used in this study (A–V) and the occurrence of WOcauB1 ORF homologues is indicated. ORF numbering refers to Fujii et al. (2004). Variant ORFs copies are identified by a small case letter. Shading indicates clusters and ORFs analysed in the study. Gp3c corresponds to an additional variant referred to as orf7 (Sanogo & Dobson 2004), absent from the wPip genome (Pel strain; Amin & Pereis 1990). At the bottom are shown wCauB WO homologues encoded in the wMel genome (cluster (A, B) and single loci (C, D), Wu et al. 2004) and the in the wSim genome (Salzberg et al. 2005), without taking into account ORF organization. wPip genome description corresponds to the current situation and will certainly change in term of clusters and copies number when the assembling is achieved.)
