“…Prior studies of muscle DMSP in wild-caught fish of a number of species (not including menhaden) have found that concentrations are usually < 20 nmol g -1 , and concentrations of ≥100 nmol g -1 are commercially problematic, because the DMS liberated during some types of processing can impart unsatisfactory tastes and odors (Motohiro 1962, Iida et al 1986, Dacey et al 1994. Our data show that in menhaden a single feeding of Prorocentrum micans drives concentrations in the swimming muscles and carcass (free of the gastrointestinal tract) to far higher levels (Table 2).…”

“…Prior information on DMSP in fish feces is sketchy (Ackman et al 1966, Dacey et al 1994. There is, however, a growing literature on DMSP in copepod and euphausid feces, emphasizing that the incorporation of DMSP into feces can greatly affect its dynamic fate by tending to send the DMSP to the bottom, facilitate its release to the water column, or enhance its accessibility to microbial metabolism (Daly & DiTullio 1996, Kwint et al 1996, Tang 2001, Yoch 2002.…”

“…Algae appear to synthesize DMSP as follows: methionine 3 4-methylthio-2-oxobutyrate 3 4-methylthio-2-hydroxybutyrate 3 4-dimethylsulfonio-2-hydroxybutyrate 3 DMSP (42). Only a limited number of species of algae and halophytes are capable of DMSP biosynthesis (28,29,54,55), and its concentration can vary considerably from one species to another (55).…”

The massive quantities of phytoplankton in the North Atlantic and Antarctic oceans producing dimethylsulfoniopropionate (DMSP) as an osmoprotectant, much of which is degraded by marine bacteria to dimethylsulfide (DMS), ensures an important role for both compounds in the global sulfur cycle. The closest to a comprehensive review on this topic is a book of symposium proceedings edited by Kiene et al. (75); the more recent developments related specifically to DMSP degradation by microbial communities are found elsewhere (68). This article is more comprehensive, as it includes some of the earlier literature in describing the sources of DMSP, its release and linkage to the marine (primarily microbial) food web and subsequent degradation via cleavage to DMS and acrylic acid or demethylation and demethiolation to methanethiol.DMS production from DMSP has long been associated with marine algae according to the following reaction (20, 22):DMSP is a tertiary sulfonium compound produced in high concentration by certain species of marine algae and plant halophytes for the regulation of their internal osmotic environment (1,41,47,120), although its role in plants remains unclear. This alga-associated, i.e., particulate DMSP (DMSPp), when released into the marine environment as dissolved DMSP (DMSPd), can serve as a link between primary production and the microbial population, as it is readily degraded by chemoheterotrophic bacteria (59). DMSP turnover usually exceeds DMS production in natural waters (60) because DMSP is also demethylated to 3-methiolpropionate, which can be further demethylated to 3-mercaptopropionate or demethiolated, releasing methanethiol (72,118). These reactions will be discussed in more detail below.The biogeochemical significance of DMSP cleavage was first suggested in 1972, when DMS was found to be universally present in seawater and emitted at a significant rate to the atmosphere (87). It was proposed that DMS, rather than H 2 S from coastal waters and mud flats, was the missing gaseous sulfur compound needed to enable the steady-state flow of sulfur between marine and terrestrial environments, making DMS emissions a key step in the global sulfur cycle (87). Atmospheric H 2 S, which arises primarily from dissimilatory sulfate reduction in organic matter-rich environments, could never be measured in sufficient quantity to be the vehicle for transferring large quantities of sulfur from sea to air to land.The total annual flux of biogenic DMS released to the atmosphere ranges from 28 to 45 Tg of S year Ϫ1 , at least 10-fold higher than from all other sources (Table 1). Recent, more comprehensive calculations of global annual DMS flux from the oceans gave values that ranged from 13 to 37 Tg of S year Ϫ1 (57). This sea-to-air flux represents about 50% of the global biogenic sulfur flux to the atmosphere (3). However, anthropogenic sulfur emissions dominate the sulfur flux, representing 80 to 90% of the input to the global sulfur cycle (12,23,88).The magnitude of the marine DMS emissions is all the more ...

“…Only a few species of higher plants have a high DMSP content, either strictly terrestrial plants such as sugar cane (Saccharum) and Wollastonia biflora and intertidal plants such as some species of Spartina (Otte et al, 2004;Dacey et al, 1987). The only study so far that has investigated the occurrence of DMSP in seagrasses was carried out by Dacey et al (1994) who attributed the occurrence of DMSP in samples from three species (Halodule wrightii, Syringodium filiforme, Thalas- * Corresponding author.

a b s t r a c tWe investigated for the first time the occurrence of dimethylsulfoniopropionate (DMSP) in the leaves of Posidonia oceanica and we report its variability during 4 sampling periods covering the seasonal cycle (February, June, August and November) and along a gradient from 10 m to 30 m depth. The P. oceanica leaf DMSP content expressed per mass of dry weight (dw) ranged from 0.1 to 33.9 mol g dw −1 and averaged 5.0 mol g dw −1 . It was higher than the DMSP content of roots and rhizomes that averaged ∼0.5 mol g dw −1 . The leaf DMSP content showed seasonal variations, being highest in summer when primary production and biomass of P. oceanica were also highest. In August, the leaf DMSP content showed variations with depth, increasing from 30 m to 10 m depth. In summer, the leaf DMSP content was highest in the youngest sections of leaves (closest to base) than in the older ones (closest to apex). The seasonal and depth distribution suggest that the DMSP leaf content is positively related to irradiance, hence, we hypothesize that DMSP in P. oceanica plays a role as an antioxidant against reactive oxygen species, although we cannot unambiguously exclude other potential roles such as grazer deterrent. The average leaf DMSP content of P. oceanica is modest compared to high DMSP producing macroalgae and phytoplankton. Yet, the integrated DMSP stock associated to the meadows of P. oceanica is very large due to its enormous biomass, and at the community level it is 2 orders of magnitude higher than the potential integrated DMSP stock related to phytoplankton in the same area.
