Inhibition of Acid-Enhanced Elongation of Zea mays Root Segments by Galactose.

abstract：:Chenopods synthesize betaine by a two-step oxidation of choline: choline --> betaine aldehyde --> betaine. The pathway is chloroplastic; the first step has been shown in isolated spinach (Spinacia oleracea L.) chloroplasts to be O(2)- and light-dependent, the role of light being to provide reducing power (P Weigel, EA...
