Abstract

The quaternary ammonium compounds (QACs1) and tertiary sulfonium com­ nitrogen or sulfur atom, creating a permanent positive charge on the N or S moiety pounds (TSCs) found in plants contain, respectively, a fully methyl substituted (190). During the last two decades the role of QACs and TSCs as nontoxic ("compatible") osmolytes, facilitating adaptation to saline or dry (26, 27, 88,89, 113,129),cyanobacteria (14, 39,147), algae (12, 32),animals (12, 42, 189), and higher plants (12, 188-190). In addition, it has become clear that environments, has been recognized in many organisms, including bacteria the TSC �-dimethylsulfoniopropionate (DMSP) is the precursor of dimethylsulfide, a major source of atmospheric sulfur main areas: (28, 81, 165). These advances have stimulated research on higher-plant QACs and TSCs in three developing analytical methods and applying them in phyto­ chemical studies; elucidating biosynthetic pathways and their genetic and environmental control; and Storey 3. understanding physiological functions.
