Transcriptomic Responses of the Marine Diatom <i>Phaeodactylum tricornutum</i> to High Carbon and Low Nitrogen Stress.

ABSTRACT: Diatoms play a pivotal role in global biogeochemical cycling and marine primary productivity, making them ideal model organisms for understanding how phytoplankton respond to environmental fluctuations associated with global climate change. In natural marine systems, diatoms frequently encounter simultaneous variations in carbon and nitrogen availability, yet most previous studies have examined the effects of these factors in isolation. To elucidate the integrated transcriptional mechanisms underlying diatom acclimation to coupled carbon-nitrogen (C-N) imbalance, we employed RNA sequencing (RNA-Seq) to characterize the global transcriptional response of the model diatom Phaeodactylum tricornutum to high CO₂ (~2000 μatm) and low nitrogen (10% of nitrogen concentration in f
