Expression profiles of differentially regulated genes during growth in magnesium and phosphate limiting medium. (A) Genes involved in nutrient transport that were induced under Mg2+ limitation. (B) Flagellar genes that were repressed under Mg2+ limitation. (C) LPS biosynthesis and anaerobic genes that were repressed under Mg2+ limitation. (D) Phosphate acquisition and phospholipid synthesis genes that were induced under PO 3-4 limitation. Bars represent fold induction or repression at 2, 4, 6, 8, and 10 h of growth scanning from left to right for any given gene fusion. The y-axis represents the fold induction or fold repression. Standard deviations were within 10% of the means.
