Light of wave lengths 0.30micro to 0.50micro, accelerates return of the cleavage rate of Arbacia eggs to normal, after delay by exposure to ultraviolet radiation (wave lengths 0.238micro to 0.31micro). Recovery is apparently complete. Wave lengths 0.30micro to 0.50micro have no effect on the cleavage rate of normal eggs, nor does such illumination previous to dosage with ultraviolet radiation influence subsequent recovery. Acceleration of recovery of the egg occurs before fertilization as well as after. The effects of ultraviolet radiation and recovery therefrom are essentially the same in nucleated "white halves" as in the intact eggs. This phenomenon in the Arbacia egg seems basically comparable to photoreactivation of bacteria and fungi.
波长在0.30微米至0.50微米之间的光，可使海胆卵在因暴露于紫外线辐射（波长0.238微米至0.31微米）而延迟后，其卵裂率恢复正常。恢复显然是完全的。波长0.30微米至0.50微米的光对正常卵的卵裂率没有影响，在紫外线辐射处理前进行这种光照也不会影响随后的恢复。卵的恢复加速在受精前和受精后都会发生。紫外线辐射及其恢复的影响在有核的“白色半卵”中与在完整卵中基本相同。海胆卵中的这种现象似乎与细菌和真菌的光复活基本类似。
