to wheat seedlings. Forty-eight hours after irradiation with Co/sup 60/ gamma rays at a dose of 10,000 r, incorporation of S/sup 35/ methionine into the total proteins of the stems was not disturbed. At the same time incorporation of S/sup 35/ methionine into the proteins of the cell fractions was changed; the incorporation of S/sup 35/ methionine tnto the protein of the mitochondrial fraction was somewhat increased, with almost no change in this respect for the nuclear and ergastoplasm fractions. Gamma radiation at a dose of 10,000 r led to depression of growth of the seedling by 23.7% and to a decrease in the number of nuclei by half. In the irradiated cell there was a distinct increase in the protein content in the mitochondrial fraction on calculation per cell. (auth)
