Ocean acidification has little effect on the biochemical composition of the coccolithophore Emiliania huxleyi

Heatmap of fold-changes of metabolites.
Fold-changes of metabolites in different pCO2 (400 vs. 1000 μatm CO2) and light acclimations (LL vs. HL, i.e., 50 vs. 300 μmol photons m-2 s-1) for diploid (2N) and haploid (1N) E. huxleyi life-cycle stages. Fold-changes of the mean values of three biological replicates were calculated. Increases are indicated in red, decreases in blue, grey boxes indicate that the metabolite was not detected in the sample. Asterisks represent p-values as determined via Student’s t-test (* represents p-values ≤0.05, ** represents p-values ≤0.01). Slashes ‘/’ indicate manually added fold-change tendencies for metabolites where the fold-change could not be calculated due to metabolites being absent or lower than the detection limit in one of the treatments. A) Metabolite fold-change per cell, B) Metabolite fold-change per POC.
