Abstract:

Zooxanthellae (Symbiodinium microadriaticum) cultured from the sea anemone Aiptasia tagetes have a characteristic circadian motility pattern. Under both a 12:12 LD and constant darkness motile cells occurred only during the light period (0800–2000), reaching peak motility 4 h after dawn; non-motile vegetative cells were always present. The pattern was lost when cells were placed under continuous illumination, implying that some period of darkness is required for the expression of the motility rhythm. Scanning electron micrographs confirmed the transition between motile and non-motile cells under an alternating photoperiod.
