Lipid Remodeling Reveals the Adaptations of a Marine Diatom to Ocean Acidification.

ABSTRACT: Ocean acidification is recognized as a major anthropogenic perturbation of the modern ocean. While extensive studies have been carried out to explore the short-term physiological responses of phytoplankton to ocean acidification, little is known about their lipidomic responses after a long-term ocean acidification adaptation. Here we perform the lipidomic analysis of a marine diatom Phaeodactylum tricornutum following long-term (∼400 days) selection to ocean acidification conditions. We identified a total of 476 lipid metabolites in long-term high CO₂ (i.e., ocean acidification condition) and low CO₂ (i.e., ambient condition) selected P. tricornutum cells. Our results further show that long-term high CO₂ selection triggered substantial changes
