GA synthesis starts in plastids, leads to the production of a linear precursor molecule geranylgeranyl diphosphate or GGPP 20C, which gets converted into ent-kaurene. This compound is oxidized in ER, leading to GA12, Dioxygenase enzymes in the cytosol are able to oxidize GA12 to all other gibberellins in pathways
