• During the early stage of germination of barley seeds the nuclear chromatin, which was diffused fibrously in the first-leaf and root meristem cells, incorporated tritiated thymidine into them. These tritium-labeled nuclei increased significantly after the treatments of gamma rays and 4-nitro-quinoline 1-oxide (4NQO). With post-treatment of 1mM EDTA, radiation-induced incorporation of tritiated thymidine into the diffuse nuclei of irradiated seeds was inhibited. The results obtained suggest that unscheduled DNA synthesis occurs in accordance with or due to chromatin diffusion in barley cells after gamma-ray irradiation and treatment with 4NQO.
