Acropora millepora adult samples: Control vs medium and high ocean acidification treatment

ABSTRACT: In this study we investigated how changes in pH and ocean chemistry consistent with the scenarios of the Intergovernmental Panel on Climate Change (IPCC) drive major changes in gene expression, respiration, photosynthesis and symbiosis of the coral, Acropora millepora, long before they affect biomineralization. Changes in gene expression were consistent with metabolic suppression, an increase in oxidative stress, apoptosis and symbiont loss. Other expression patterns demonstrated up-regulation of membrane transporters, as well as the regulation of genes involved in membrane cytoskeletal interactions and cytoskeletal remodeling. These widespread changes in gene expression emphasize the need to expand future studies of ocean acidification to include a wider spectrum of cellular processes, many of which may occur well before impacts on calcification.
