Heat maps of selected functionally relevant genes that are significantly altered in transcriptional levels from each expression profile examined. (A) Selected genes of the V. cholerae genome believed to be responsible for VPS biosynthesis. (B) Selected genes functionally categorized as having a role in cellular processes, including many genes thought to be involved in flagellar biosynthesis, motility, and chemotaxis. (C) Genes involved in iron transport and VAS. Compact views of genes are presented using the log2-based color scale shown at the top right. Yellow, induced; blue, repressed; black, no significant change.
