A Potential Role for Epigenetic Processes in the Acclimation Response to Elevated pCO₂ in the Model Diatom Phaeodactylum tricornutum.

ABSTRACT: Understanding of the molecular responses underpinning diatom responses to ocean acidification is fundamental for predicting how important primary producers will be shaped by the continuous rise in atmospheric CO₂. In this study, we have analyzed global transcriptomic changes of the model diatom Phaeodactylum tricornutum following growth for 15 generations in elevated pCO₂ by strand-specific RNA sequencing (ssRNA-seq). Our results indicate that no significant effects of elevated pCO₂ and associated carbonate chemistry changes on the physiological performance of the cells were observed after 15 generations whereas the expression of genes encoding histones and other genes involved in chromatin structure were significantly down-regulated, w
