Osmotic stress induces expression of choline monooxygenase in sugar beet and other crops.
Salinity promotes accumulation of dimethylsulfoniopropionate and its precursor S-methylmethionine in chloroplasts. Transgenically expressed betaine aldehyde dehydrogenase efficiently catalyzes oxidation of dimethylsulfoniopropionaldehyde and omega-amino aldehydes. 20 Jan 1994, Vol. Australian Jour. of Plant Physiol. Cultivated and wild rices do not accumulate glycinebetaine due to deficiencies in two biosynthetic steps.
