Overview
Gibberellin A4 is a C19-gibberellin, initially identified in Gibberella fujikuroi and differing from gibberellin A1 by the substitution of the OH at C-7 (gibbane numbering) by H. It has a role as a plant metabolite. It is a C19-gibberellin, a lactone and a gibberellin monocarboxylic acid. It is a conjugate acid of a gibberellin A4(1-).
