Betaine Synthesis from Radioactive Precursors in Attached, Water-stressed Barley Leaves 12

RESUMO
In wilted barley leaves, betaine accumulates at about 200 nanomoles per 10 centimeters leaf per day. Results with 14C-labeled precursors were qualitatively and quantitatively consistent with de novo synthesis of this betaine from serine via ethanolamine, choline, and betaine aldehyde and indicated that water stress may increase the activities of all steps in this pathway except the last.
