- The conversion of nicotinic acid to N-conjugates by either m ethylation or glucosylation has been investigated in leaves and tubers from potato plants, in potato callus and suspension cultures and in plants regenerated from such cultures. While nicotinic acid-N-glucosyltransferase activity could be detected in the cells and tissues at each level of differentiation, the N-methyltransferase (trigonelline formation) was only found in organized leaf tissue.
