Cilia were removed from blastulae, gastrulae, and plutei of the sea urchins Arbacia punctulata and Lytechinus variegatus by shaking the embryos in hypertonic media. Exposure to 50 krad (and in some experiments 100 krad) of ..gamma.. radiation either before or after deciliation had no effect on the time of appearance of regenerating cilia. There were no visually obvious differences in the rate of growth of the cilia in control and irradiated embryos. The cilia commenced beating at the same time, but the initial beating sometimes seemed less vigorous following irradiation. The data support the hypothesis that radiation has no major effect on the assembly from mature basal bodies of the microtubules of cilia.
