Gibberellin, commonly abbreviated to GA, is a member of a group of naturally occurring tetracyclic diterpenoid carboxylic acids, most of which possess the ent -gibberellane (C 20) or ent -20-norgibberellane (C 19) carbon skeletons. Currently 136 different GAs have been identified from higher plants, fungi, or bacteria.
