Physical map of the genomic region containing the XaPPTase gene in Xanthomonas oryzae strains and of the corresponding region in other sequenced species of Xanthomonas . White arrows: gene vipA (probable UDP-glucose/GDP-mannose dehydrogenase gene) and gene pgsA (probable CDP-diacylglycerol-glycerol-3-phosphate-3-phosphatidyltransferase gene). Dark grey arrows: XaPPTase gene (encoding a 4′-phosphopantetheinyl transferase active on peptidyl carrier protein domains). Light grey arrows: NRPS (nonribosomal peptide synthesis) genes. Coloured arrows correspond to genes described in Figures 3 and 4. Hp: hypothetical protein gene (ortholog of accession Dd703_3065 of strain Ech703 of Dickeya dadantii). TA: transaminase gene (ortholog of accession Dd703_3064 of strain Ech703 of D. dadantii). DH: lactate dehydrogenase gene. DaT: gene involved in biosynthesis of 2,4-diaminobutyric acid (Dab). Length of arrows is not proportional to the length of genes. Salmon-coloured oval circle: Eight genes present in contig 112.1 of X. oryzae strain X11-5A that are conserved in other strains of X. oryzae and are not predicted to be involved in NRPS biosynthesis. : tRNA. Orientation of the tag indicates the orientation of the tRNA gene in the genomic regions. Amino acid specificity of each tRNA is indicated above or below each tag according to the orientation of the tRNA gene. ???? : undetermined sequence located between contigs. Two contigs separated by this tag may be located in two different genomic regions (they are not necessarily contiguous). : this tag indicates that corresponding genomic regions are not contiguous. Data on strain CFBP4834-R of X. axonopodis pv. phaseoli were obtained from an unpublished finished genome sequence (M.-A. Jacques, personal communication).
