Prolonged light exposure time enhances the photosynthetic investment in osmotrophic <i>Ochromonas</i>.

ABSTRACT: The photoperiod, as a critical external environmental signal, triggers a cascade of signaling responses in organisms that significantly affect photosynthetic efficiency and photomorphogenesis in autotrophs, while also influencing behavioral patterns and activity rhythms of heterotrophs. Despite its importance, the mechanisms by which mixotrophs respond to photoperiod changes remain largely unexplored. It is crucial for understanding metabolic plasticity how mixotrophs respond to light availability and make optimal decisions during diurnal transitions by regulating their autotrophic and osmotrophic pathways. Therefore, this study focused on Ochromonas gloeopara, a eukaryotic protist capable of both photoautotrophic and osmotrophic growth, aiming to explore the metabolic strategies of
