与大多数昆虫一样，果蝇的视觉系统对从紫外线到绿色的光谱敏感，但对红光不敏感。然而，果蝇的昼夜节律可以通过未知的机制被红光携带。在这里，我们发现了相应的器官和色素负责的昼夜夹带果蝇的红光从发光二极管。通过使用Eya（2）或NorpA（P24）的复眼光输入的损失来消除夹带。我们还发现双视紫红质I（ninaE）和视紫红质突变体不被夹带到红光。这些结果表明果蝇复眼中的视紫红质I和视紫红质6可以诱导果蝇对红光的昼夜节律。NeuroReport 19：1441-1444（C）2008 Wolters Kluwer Health \ Lippincott威廉姆斯& Wilkins.
Like most other insects, Drosophila visual system is sensitive to the spectrum of light from ultraviolet to green but is insensitive to red light. The circadian rhythms of Drosophila, however, can be entrained by red light through unknown mechanisms. Here, we discovered the corresponding organ and photopigments responsible for the circadian entrainment of Drosophila to red light from light emitting diode. The entrainment was eliminated by the loss of photic input from compound eyes using eya(2) or norpA(P24). We also found that the double Rhodopsin I (ninaE) and Rhodopsin mutant was not entrained to red light. These results indicate that Drosophila can entrain the circadian rhythm to red light through Rhodopsin I and Rhodopsin 6 in compound eyes.
