Betaine is synthesized by a two-step oxidation of choline in which mitochondrial choline oxidase first catalyzes the production of betaine aldehyde, which is further oxidized by mitochondrial betaine aldehyde dehydrogenase to betaine (Dragolovich, 1994).

GB nonaccumulation appears to be caused by recessive alleles of a single locus in maize (Rhodes and Rich, 1988; Rhodes et al., 1989) that results in an inability to convert choline to betaine aldehyde, the first committed step in the synthesis of GB (Lerma et al., 1991).
An important metabolic pathway for choline involves its conversion into glycine via betaine aldehyde, betaine, N,N-dimethylglycine (DMG) [6] and sarcosine (Fig.

Rice does not accumulate glycine betaine as does barley and other plants (Ishitani et al., 1993) because of a deficiency in choline monooxygenase and betaine aldehyde dehydrogenase (Rathinasabapathi et al., 1993).
