Diatom Acclimation to CO2

Gwenn Hennon and co-authors have published a new study in the journal Nature Climate Change describing how diatoms adjust metabolism and gene expression under rising CO2. Hennon et al. found that expression of carbon concentration and photorespiration genes are coordinated by signaling with the small molecule cyclic-AMP, which may be a deeply conserved mechanism of CO2-regulation in diatoms.
