Stem segments excised from light-grown Pisum sativum L. (cv. Little Marvel) plants elongated in the presence of indole-3-acetic acid and its precursors, except for L-tryptophan, which required the addition of gibberellin A, for induction of growth. Segment elongation was promoted by D-tryptophan without a requirement for gibberellin, and growth in the presence of both D-tryptophan and L-tryptophan with gibberellin A3, was inhibited by the D-aminotransferase inhibitor D-cycloserine. Tryp-tophan… CONTINUE READING
