Abstract

The levels of nuclear mRNAs for three light-inducible proteins (light-harvesting chlorophyll a/b protein, small subunit of ribulose-1,5-bisphosphate carboxylase and early light-induced protein) have been analyzed under light-dark and constant light conditions. The levels of all three mRNAs have been found to vary considerably during the day, both under ligh-dark and under constant light conditions, demonstrating the existence of diurnal and circadian rhythmicity in the expressionoof these nuclear-coded plant proteins. The levels of two of these mRNAs have been found to be enhanced 2 h before the beginning of illumination when active phytochrome levels are still low.
