Schematic diagram of the S. enterica genes that are involved in propanediol (pdu) and ethanolamine (eut) utilization, the biosynthesis of their essential cofactor cobalamin (vitamin B₁₂) (cob and cbi), and the catabolism of rhamnose (rha) and fucose (fuc), two precursors of the propanediol pathway. Numbers in block arrows represent the fold increases in gene expression levels in cilantro soft rot lesions compared with levels in LB culture. Cross-hatched arrows illustrate that the gene was not differentially regulated more than 2-fold. The orientation of block arrows indicates the orientation of transcription. Pathways are based on diagrams described previously by Price-Carter et al. (17). TCA, tricarboxylic acid.
