Metabolism of Tritiated Gibberellins in d-5 Dward Maize: II. [3H]Gibberellin A1, [3H]Gibberellin A3, and Related Compounds 1

AUTOR(ES)
RESUMO

After 30 minutes of incubation of young leaf sections of d-5 maize (Zea mays L.) in [3H]gibberellin A1 ([3H]GA1), the metabolite [3H]GA8 was present in significant amounts, with a second metabolite, [3H]GA8-glucose ([3H]GA8-glu), appearing soon after. A third [3H]GA1 metabolite, the polar uncharacterized conjugate [3H]GA1-X, took more than 1 hour to appear. The protein synthesis inhibitor cycloheximide inhibited the production of all [3H]GA1 metabolites, indicating a possible protein synthesis requirement for [3H]GA1 metabolism.
