Title	Unveiling Seasonal Adaptive Molecular Mechanisms in Marine Phytoplankton during Diel Cycles through Multiomics Integration
Description	Earth tilted rotation and translation around the Sun produce one of the most pervasive rhythms on our planet, giving rise to seasonal variations in diel cycles. Although marine phytoplankton plays a key role on ecosystems, multiomics analysis of its response to these periodic environmental signals remains largely unexplored. The marine picoalga Ostreococcus tauri, which resides at the base of the green lineage, has been chosen as model organism due to its high abundance in marine phytoplankton and its cellular and genomic simplicity, making it the smallest free living eukaryote. Ostreococcus was subjected to different light regimes: summer long days, winter short days, constant light and constant dark conditions, to investigate these responses. Although 80% of the transcriptome presented diel rhythmicity, less than 5% maintained oscillations under constant conditions. A drastic reduction in proteome rhythmicity was observed with 55% of the proteins oscillating. Seasonal specific rhythms were found for key physiological processes such as cell cycle, photosynthesis, carotenoid biosynthesis, starch accumulation and nitrate assimilation. In this study, a global orchestration between transcriptome, proteome and physiological dynamics was characterised identifying specific seasonal temporal offsets between peaks in transcripts, proteins, and physiological responses.
