Transcription start sites for PSPTO_0444-, PSPTO_1209-, and PSPTO_1286-regulated genes. Transcript 5′ ends were mapped on the P. syringae DC3000 genome sequence using 5′ RACE as described in reference 11. Potential start sites are indicated with bold type. Multiple boldface nucleotides shown for PSPTO_1207 and PSPTO_1286 indicate uncertainty regarding the position of the 5′ end due technical limitations that prevent mapping the start site to a single nucleotide. The annotated ATG initiation codon is at the 3′ end of each sequence, followed by the gene name. The locations of Fur boxes from reference 13 are indicated in gray shading. PSPTO_0444, PSPTO_1209, and PSPTO_1286 were expressed from pBS161, pBS164, and pBS165, respectively.
