Summary
5-3H-uridine injected into the stylar canal of detached lily stigma-styles was taken up initially into the rapidly-labeled-RNA of the nucleic acid profile of a methylated albumin kieselguhr (MAK) column but with increasing time was found in all portions of the RNA profile, but not in the DNA. Heat treatment of the style before injection of 5-3H-uridine greatly reduced the rate of incorporation of label into and the ultimate amount of label found in the RNA species of the lily style. Translocation of 5-3H-uridine through the ovary into heattreated pistils and the injection of 5-3H-uridine into styles which had been incubated for 1 or 2 days after heat treatment resulted in stylar nucleic acids more highly labeled than nucleic acids in control styles, with an incorporation pattern different than control styles. Heat treatment of lily pistils resulted in detectable changes in the proportion of stylar RNA species as separated on MAK columns and measured as absorbance units. Actinomycin D and 6-methylpurine treated styles incorporated label from a stylar injection of radioactive uridine in patterns different than each other, different than heat-treated styles and different than non-treated styles. 6-methylpurine and heat treatment of styles only slightly reduced the rate at which 5-3H-uridine was removed from the stylar canal into the stylar tissue.
