1 Tiny marine plants (phytoplankton) use sulfate, a common salt in the ocean, to produce a chemical called dimethylsulfoniopropionate
The biogenic, sulfur-containing molecule dimethylsulfoniopropionate
(DMSP) is synthesized by open-ocean phytoplankton (single-celled plants) (Dacey and Wakeham, 1986; Dacey et al., 1987; Matrai and Keller, 1994).
DMS is made from a larger chemical compound called dimethylsulfoniopropionate
, or DMSP, which is made by tiny marine plants, or phytoplankton (see Page 28).
The bacteria may benefit by having a readily available source of organic compounds such as dimethylsulfoniopropionate
(DMSP), a preferred source of reduced sulfur (Miller and Belas, 2004; Raina et al, 2010).
Transcriptional response of Silicibacter pomeroyi DSS-3 to dimethylsulfoniopropionate
In open-ocean habitats at polar latitudes, for example, dimethylsulfoniopropionate
(DMSP) and its metabolites (dimethyl sulfide and acrylate) convey information among several trophic levels, including large pelagic predators, in planktonic food webs (Nevitt et al., 1995; Wolfe et al., 1997; Steinke et al., 2006; Pohnert et al., 2007).
Tridacnids are thus candidates to have high tissue concentrations of dimethylsulfoniopropionate
(DMSP), a tertiary sulfonium compound that is not synthesized by animals but is commonly produced by dinoflagellates.
These cells have extremely high concentrations of dimethylsulfoniopropionate
(DMSP) that equalize osmotic pressure between the cytoplasm and external ocean environment, thus maintaining a constant cell volume (Vairavamurthy et al., 1985; Dacey et al., 1987; Matrai and Keller, 1994).
As an example, I detail an algal dimethylsulfoniopropionate
(DMSP) cleavage reaction that appears to deter protozoan feeding and explore it as a possible model for a rapidly activated, short-range chemical defense system.
Marine DMS is a byproduct of the metabolic decomposition of dimethylsulfoniopropionate
(DMSP) in marine phytoplankton (most notably Phaeocystis pouchetii).
