Figure 1.

A heat map of relative fold change in gene expression of genes involved in virulence and colonization (hilA, InvA) and fatty acid synthesis (cfa, fabB, fadD, fabA) in 15 Salmonella enterica serovars artificially inoculated into poultry feed and sampled after incubation at room temperature at 4 h (panel A), 8 h (panel B), and 24 h (panel C). Maps are sorted based on the cfa gene in ascending order of regulation for each time point. cfa = cyclopropane fatty acid gene; fabA, fabB, and fabD = fatty acid biosynthesis genes.
