The effect of chronic and acute low pH on the intracellular DMSP production and epithelial cell morphology of red coralline algae
The release of dimethylsulphoniopropionate (DMSP) by marine algae has major impacts on the global sulphur cycle and may influence local climate through the formation of dimethylsulphide (DMS). However, the effect of global change on DMSP/DMS (DMS(P)) production by algae is not well understood. This...
