DNA Microarray Analysis of the Effects of Mn2+ Depletion on Gene Expression in Wild-Type, ΔmanS, and ΔmanR Cells.
Gene expression in wild-type (A), ΔmanS (B), and ΔmanR (C) cells that had been incubated for 24 h under Mn2+-depleted conditions (in BG-11 medium to which no MnCl2 had been added) was compared with that in corresponding cells that had been grown in the presence of adequate concentrations of Mn2+ ions (in BG-11 medium that contained 9 μM MnCl2).
