Figure S8: DNA staining of cells with and without YgjD in TB80 (ppGpp+) and TB84 (ppGpp0). Cells were grown for two hours in liquid culture, and stained with 1 μg/ml DAPI (4',6-diamidino-2-phenylindole) to visualize DNA. Scale bars are 5 μm. A) TB80 grown with 0.1% arabinose to induce YgjD expression. B) TB80 grown with 0.4% glucose, leading to YgjD depletion. Cells are small, and the DNA stain occupies a large fraction of the cell area. C) TB84 grown with 0.4% glucose, leading to YgjD depletion. Cells are elongated, and the DNA stain only occupies a small fraction of the cell area.
