A life cycle of many known algae is influenced by the circadian clock. It seems probable that also Chromera velia, the closest known photosynthetic relative to Apicomplexa, uses circadian oscillator. We tested, if fluctuating of zoospore?s abundance is driven by the circadian clock. This rhythm is stable even in the constant light condition. Furthermore, three cryptochrome genes, involved in circadian rhythms, were sequenced and consequently phylogenetically investigated. Two of them were classified as CRY-DASH, the third is CRY-DASH-like. The rhythmicity of CRY-DASH expression in C. velia was also investigated. The level of expression was also tested under constant light and dark condition. It was suggested that expression of these genes is associated with the circadian oscillator. This is the first study of the circadian clock in C. velia.
