Abstract

The action of light on ribosome formation was examined in the cabbage seedlings, a system extensively used in the studies of anthocyanin synthesis. Ribosomes were extracted 18 h after the beginning of the irradiation and separated by sucrose gradient centrifugation. In the cotyledons of dark-grown cabbage seedlings, a brief red light induces an increase both in total ribosomes and in the fraction present as polysomes; the effect of red light is reversed by far red light, indicating the involvement of phytochrome in polysome formation in cabbage seedlings. Continuous red and continuous far red light are about equally effective in bringing about an increase of total ribosomes and of the polysome fraction. Streptomycin, which inhibits chlorophyll synthesis and chloroplast development, and enhances anthocyanin synthesis in cabbage seedlings, causes a decrease of total ribosomes and of the fraction present as polysomes. In hypocotyls, the red-far red reversibility is evident only for the polysome content and streptomycin does not decrease the polysome/monosomo ratio as it does in cotyledons.
