title: Niacin Biosynthesis in Seedlings of Zea mays.
abstract: Evidence obtained from incubation of corn (Zea mays cv. Golden Bantam) seedlings in dl-[benzene ring-U-(14)C]tryptophan, l-[5-(3)H]tryptophan, l-[U-(14)C]aspartate and [U-(14)C]glycerol indicates that niacin is synthesized in these plants via oxidative degradation of tryptophan. Aspartate and glycerol do not appear to be precursors of niacin in corn seedlings.
