Latitudinal diversity in circadian and light-sensing genes in an ecologically vital group of marine picoeukaryote algae.

ABSTRACT: Organismal life cycles are influenced by Earth's rotation and orbit, generating daily and seasonal light cycles that vary with latitude, especially in temperate and polar zones. Photoperiodism relies on organisms' ability to measure time via the circadian clock and detect light through specific photoreceptors. Molecular basis of photoperiodism is well-characterized in plants, but photoperiod adaptation in phytoplankton remain largely unexplored. Here, we investigated circadian clock components, photoreceptors, and associated effectors in eukaryote picoalga species from Ostreococcus, Bathycoccus, and Micromonas. We showed that the investigated species shared a conserved set of homologous circadian clock-related genes that appeared in the early evolution of Mamielalles order. Furthermore, ge
