Etiolated Plants

Illumination of etiolated plants effects the activity of protochlorophyllide reductase (NADPH-protochlorophyllide oxidoreductase) in the plastids. Constant illumination or a 2-min light-triggering of etiolated plants leads to an approx. 80% decrease in activity of the enzyme, a change that can be reversed by returning the plants to darkness. The change in activity results from an alteration of the Vmax. rather than Km. Despite the fact that exogenous pigments effect the activity of the enzyme in vitro, no correlation could be drawn between the concentrations of pigments in vivo and activity of the enzyme.
