Effect of GSH on the growth of R. solanacearum in minimal medium. R. solanacearum strains RS1002 (wild type [solid circles]) and RS1701 (ΔgshAB [open circles]) were diluted in 1/4 M63 glucose minimal medium to an OD₆₀₀ of 0.1 as described in Materials and Methods. The cultures were incubated at 28°C, and their cell densities were measured over the time course given. The growth of RS1701 was also measured with 1/4 M63 glucose minimal medium supplemented with 1 mM GSH (open triangles). The data are means from three independent experiments.
