Abstract

A comparison of the results of feeding -7-hydroxygibberell-16-en-19-oic acid, -7-oxogibberell-16-en-19-oic acid, and -gibberell-16-ene-7,19-dioic acid (gibberellin A), in terms of the distribution of mevalonate, to , reveals that there is a divergence between the pathways leading to the 3-hydroxylated and the non-3-hydroxylated gibberellins at the C-7 aldehyde stage. The distribution of label between the C and C gibberellins after 6 and 24 h incubations suggests that the free C gibberellins (A, A, A, and A or A, A, and A) may not lie on the direct pathway to the C gibberellins. Gibberellins A and A are transformed into gibberellic acid. Incubation of gibberellin A with may be used to prepare gibberellins A and A.
