Plants synthesize betaine by a two-step oxidation of choline (choline --> betaine aldehyde --> betaine). Protoplast-derived chloroplasts of spinach (Spinacia oleracea L.) carry out both reactions, more rapidly in light than in darkness (AD Hanson et al. 1985 Proc Natl Acad Sci USA 82: 3678-3682). We investigated the light-stimulated oxidation of choline… CONTINUE READING
