• The distribution of dimethylsulfoniopropionate in tropical Pacific coral reef invertebrates (2006, background): “In phytoplankton, DMSP, DMS, acrylate and acrylic acid can all scavenge ROS, but DMS and acrylic acid are the most effective scavengers (Sunda et al. 2002).”
• The effect of nitrogen limitation on cellular DMSP and DMS release in marine phytoplankton: climate feedback implications (2007, background): “These include active grazing defense due to the toxicity of acrylate to zooplankton (Wolfe et al., 1997) and antioxidant protection owing to the ability of DMSP, acrylate, DMS, and the oxidation product dimethylsulfoxide to scavenge hydroxyl radicals and other reactive oxygen species ( Sunda et al.,”
• DMSP in marine macroalgae and macroinvertebrates: Distribution, function, and ecological impacts (2007, background): “Although DMSP itself is not a strong antioxidant, its cleavage products DMS and acrylic acid are effective at consuming ROS (Ross and Van Alstyne, 2007; Sunda et al. , 2002).”
• Pelagic functional group modeling: Progress, challenges and prospects (2006, positive): “The Sunda et al. (2002) antioxidant hypothesis suggests that phytoplankton synthesize DMSP, which is converted intracellularly to DMS, as a method to cope with high levels of oxidative stress resulting from high ultraviolet (UV) light exposure, metal toxicity or low nutrient concentrations.”
• Environmental constraints on the production and removal of the climatically active gas dimethylsulphide (DMS) and implications for ecosystem modelling (2007, background): “This may be supportive of an antioxidant function, but also shows that short-term effects can be opposite to long-term effects as presented by Sunda et al. (2002) and as shown in Fig.”
• Current understanding of Phaeocystis ecology and biogeochemistry, and perspectives for future research (2007, background): “DMSP has properties in common with the compatible solute glycine betaine, and production of DMSP and DMS may be related to physiological stress (Stefels 2000; Sunda et al. 2002).”
• Algae as nutritional and functional food sources: revisiting our understanding (2016, neutral): “2002), L-proline (Smirnoff and Cumber 1989), dimethylsulfoniopropionate (Sunda et al. 2002), and floridoside and isofloridoside (Li et al.”
• Anaerobic Metabolism: Linkages to Trace Gases and Aerobic Processes (2003, background): “DMSP is produced by marine micro- and macroalgae and halophytic plants where it acts as an osmoregulant or as part of an antioxidant system (Sunda et al., 2002; Yoch, 2002).”
• Chemical defense in the microplankton II: Inhibition of protist feeding by β‐dimethylsulfoniopropionate (DMSP) (2003, background): “High intracellular levels of DMSP, hypothesized to act as an antioxidant, are produced by some algal species in response to chronic iron limitation, elevated CO2, and ultraviolet exposure (Sunda et al. 2002), all sources of oxidative stress.”
• The case against climate regulation via oceanic phytoplankton sulphur emissions (2011, background): “The proposed climate feedback loop requires (1) that DMS is a significant source of CCN to the MBL, (2) a change in DMS-derived CCN yields a change in cloud albedo, and (3) a change in cloud albedo, surface temperature, and/or incident solar radiation leads to a change in DMS production.”
• Organic osmolytes as compatible, metabolic and counteracting cytoprotectants in high osmolarity and other stresses (2005, background): “·2), a major osmolyte of marine algae, also has antioxidant properties (Sunda et al., 2002).”
• Dissolved organic matter (DOM) release by phytoplankton in the contemporary and future ocean (2014, background): “The physiological functions of DMSP andDMS are uncertain, though they may be components of an intracellular antioxidant system (Sunda et al., 2002).”
• Novel copper‐binding and nitrogen‐rich thiols produced and exuded by Emiliania huxleyi (2004, background): “1986), especially in combination with its high DMSP content, which might provide a scavenging mechanism for ·OH radicals generated by redox reactive copper (Sunda et al. 2002).”
