Abstract

Evidence obtained from incubation of corn (Z. mays cv. Golden Bantam) seedlings in DL-[benzene ring-U-14C]tryptophan, L-[5-3H]tryptophan, L-[U-14C]aspartate and [U-14C]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.
