The effect of dimethyl sulphoxide on electron transport in chloroplasts.
The effect of DMSO (dimethyl sulphoxide) on electron transport in chloroplast membranes has been studied. It has been found that concentrations of DMSO up to 20% (v/v) do not inhibit electron transport in freshly isolated chloroplasts, but that higher concentrations start to cause inhibition. However, in chloroplasts that have been aged for 8 to 24 hours by storage at 4 degrees C, the addition of DMSO at concentrations up to 20% causes stimulation of electron transport. Possible mechanisms for this effect are discussed.
