Light-dependent incorporation during subjective day and night of radioactive uridine into RNA of a long-day duckweed, Lemma gibba G3, was examined. When the dark treatment was started from the subjective night phase, the activity of uridine incorporation dropped approximately by half only after the very subjective night phase had passed or with the commencement of the subsequent subjective day phase. However, when the dark treatment was started from the subjective day phase, the incorporating activity promptly began to decrease and the inhibition increased with the length of the dark period until a final steady level (also at ca. 50% of the initial level) was reached after 24 hr of darkness. These two phases of different light sensitivities recurred daily under control of the physiological clock and the rhythm was reset by a light-on signal. The lowered incorporating activity due to the darkened day phase was recovered completely by a 12-hr or even 15-min white light period perturbing the succeeding night phase. That the incorporation of uridine in every RNA species, especially in chloroplast ribosomal RNA, was lowered by dark treatment of the day and night phases, was disclosed by MAK column chromatography and acrylamide gel electrophoresis.
