| 内容記述 | We examined the effects of photoperiod, wavelength and light fluence rate on diurnal vertical migration (DVM) cycle in a coastal raphidophyte, Chattonella antiqua. We first observed the DVM under different combinations of light–dark (LD) cycles and light spectra. Under continuous white, UV-A or blue light, DVM followed the LD cycle established during the white light pre-conditioning, for one cycle, and then became arrhythmic. Under red light, however, the DVM rhythms under the different LD regimes continued approximately as during pre-conditioning. When C. antiqua cultured under continuous red light was exposed to a 2-h pulse of blue light at the beginning or end of artificial ‘night’, the DVM was delayed or advanced, respectively. The fluence rate–response curve indicates a blue-light threshold of 10–2 μmol photons m–2 s–1 for the DVM phase shift. The equal-quantum action spectra for phase shift peaked in the UV-A/blue region (360–480 nm), which is the part of the light spectrum most transmitted in its natural habitat. We show that C. antiqua can sense the weak blue component of sunlight throughout its depth range, allowing it to cue its DVM to the day–night cycle regardless of weather and transparency. | |||||
