“…3). This spectrum was identical to those obtained with authentic choline-0-sulfate, and the chemical shifts correspond closely to published values (Catalfomo et al 1973;Blunden and Gordon 1986).…”

“…Choline-0-sulfate (sulfuryl choline) occurs widely among marine algae (Blunden and Gordon 1986) and marine fungi (Catalfomo et al 1973), as well as in certain other fungi and bacteria (e.g. Gravel 1976;Fitzgerald and Luschinski 1977).…”

“…Gravel 1976;Fitzgerald and Luschinski 1977). Besides functioning as a sulfur storage compound (Gravel 1976), choline-0-sulfate in these organisms has been considered as a possible detoxification product of sulfate anion (Catalfomo et al 1973) or a possible compatible cytoplasmic solute (Blunden and Gordon 1986). The latter idea is supported by demonstrations that supplied choline-0-sulfate can alleviate osmotic inhibition of growth in bacteria (Mason and Blunden 1989;Hanson 1991).…”

A sensitive and specific method was developed for determining choline-0-sulfate by fast atom bombardment mass spectrometry, using a deuterium labelled choline-0-sulfate internal standard. This method was used to survey leaves or shoots of 30 native halophytic species from 14 families, collected from temperate and subtropical saline habitats. Twenty-three species had very little choline-0-sulfate (< 1-2 pmol g-' dry wt) but Avicennia germinans contained 8 pmol g-' dry wt, and all six members of the family Plumbaginaceae surveyed (Limonium spp. and Armeria maritima) accumulated > 100 pmol g-' dry wt. Three cultivated Limonium species were also found to accumulate choline-0-sulfate when salinised with NaCl or with NaCl plus Na2S04 under controlled environmental conditions. The identity of choline-0-sulfate in Limonium species was confirmed by high resolution and tandem mass spectrometry, by 'H nuclear magnetic resonance, and by analysis of hydrolysis products. Tests with Limonium leaf disks showed that the salt glands of this genus secrete very little sulfate. Possible roles for choline-0-sulfate in osmotic adjustment and sulfate detoxification are discussed.O3lO-7841/9l/O4O3 l7$OS. OO

“…Third, the correlations between Is and total QAC concentration, and between Is and individual QACs, are very similar to those for glycine betaine in members of the Chenopodiaceae (8,22), in which glycine betaine is known to be located in the cytoplasm (15). (3,7), such interpathway competition may be disadvantageous in sulfate-rich habitats. The second metabolic factor is the oxygen requirement of the first step in choline oxidation to glycine betaine (2), which would impair glycine betaine synthesis in roots under the severe hypoxia that often prevails in salt marshes.…”

“…1). Again, like glycine betaine, both are accumulated by certain marine algae and other marine organisms (1,3), and neither is inhibitory at high concentrations to isolated enzymes (16,20). On these grounds, it seems possible that ,3-alanine betaine and choline-O-sulfate could supplement or supplant glycine betaine as a cytoplasmic osmolyte.…”

The quaternary ammonium compounds accumulated in saline conditions by five salt-tolerant species of Limonium (Plumbaginaceae) were analyzed by fast atom bombardment mass spectrometry. Three species accumulated j-alanine betaine and choline-O-sulfate; the others accumulated glycine betaine and choline-C-sulfate. Three lines of evidence indicated that f,-alanine betaine and choline-0-sulfate replace glycine betaine as osmoregulatory solutes. First, tests with bacteria showed that 0-alanine betaine and choline-0-sulfate have osmoprotective properties comparable to glycine betaine. Second, when ,B-alanine betaine and glycine betaine accumulators were salinized, the levels of their respective betaines, plus that of choline-0-sulfate, were closely correlated with leaf solute potential. Third, substitution of sulfate for chloride salinity caused an increase in the level of choline-C-sulfate and a matching decrease in glycine betaine level. Experiments with '4C-labeled precursors established that B-alanine betaine accumulators did not synthesize glycine betaine and vice versa. These experiments also showed that 6-alanine betaine synthesis occurs in roots as well as leaves of fialanine betaine accumulators and that choline-C-sulfate and glycine betaine share choline as a precursor. Unlike glycine betaine, j-alanine betaine synthesis cannot interfere with conjugation of sulfate to choline by competing for choline and does not require oxygen. These features of #l-alanine betaine may be advantageous in sulfate-rich salt marsh environments.Considerable evidence indicates that the QAC2 glycine betaine accumulates in the cytoplasm and chloroplasts of species of the family Chenopodiaceae during osmotic stress and acts as a nontoxic or compatible osmolyte (for reviews, see refs. 15 and 28). Glycine betaine is likely to play the same role in the many other angiosperm families in which it accumulates in response to stress (27,30), although in these cases the '
