Cell suspension cultures of various crop plants have been used for studying salt and drought stress on the GSH/GSSG‐system, As already recorded for whole plants, cell cultures of different species vary in their glutathione levels. In general, cell cultures of species with relatively high glutathione content are more tolerant to abiotic stress. A high glutathione content alone is not adequate to prevent cell damage and a decrease in cell growth. E.g. the addition of sulphur to stressed cell cultures slightly enhances the GSH content but does not enhance the adaptation of these cells to stress. Thus, the role of glutathione in the adaptation of cells to stress situations seems to be only one component in a more complex response mechanism.
