Co-transcription of the P. syringae pv. tomato DC3000 matE and iaaL genes. a A diagram of the matE and iaaL genes is shown. The direction of transcription is indicated by the arrows. Triangles represent hrp box promoters, and the hexagon shows a putative transcriptional terminator predicted using a web interface [50]. Solid and dashed lines represent RT-PCR products. Sequenced products are indicated by solid lines. b Agarose gel electrophoresis of RT-PCR products encoding the intergenic regions of the matE-iaaL operon. The sizes of the products are indicated on top of the lanes. + and − indicate reaction mixtures containing or lacking Pto DC3000 c-DNA, respectively. At the left, a 1-Kb molecular ladder is shown
