The biosynthesis of gibberellins is under strict genetic, developmental, and environmental control, and numerous gibberellin-deficient mutants have been isolated. 

Mendel’s tall/dwarf alleles in peas are a famous example. Such mutants have been useful in elucidating the complex pathways of gibberellin biosynthesis.

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
