摘要：

The effects of ultraviolet light (UV) on the gastrulation of sea urchin embryos were examined. The results suggest that gastrulation is inhibited by UV irradiation and that stage sensitivity to UV suppression of gastrulation changes biphasically: higher sensitivity at early and late blastula, and lower sensitivity at the mid-blastula stages. The UV-induced inhibition of gastrulation was completely reversible by subsequent exposure to visible light.
