Abstract: Red light suppressed the protein and chlorophyll loss in the disks excised from matured tobacco leaves and floated on water. The red effect was removed by subsequent far-red irradiation and by several inhibitors of protein and nucleic acid synthesis.Red light remarkably promoted the uptake of 32PO4, which could be reversed partly by subsequent far-red irradiation. The absorbed 32PO4 was recovered mainly in acid-insoluble fraction. A remarkable parallelism was found between the sensitivity to red light and the activity of 32PO4 incorporation. Each passed an acute peak at about the 34th hour of incubation.Kinetin inhibited 32PO4 uptake, but induced slightly additive restoration of protein, and chlorophyll levels when it was given together with red light.A participation of red far-red system in protein and phosphate metabolism in leaves was suggested.
