The stages of gibberellin biosynthesis takes place various organelles and completed in various forms such as;

a) In the endoplasmic  reticulum GA12 is converted to GA53 by hydroxylation at C-13

b) In the cytosol GA12 is converted via 13-hydroxylation pathway into GA9 and further converted into GA4 by 3-β-Hydroxylation

c) In the cytosol GA53 is converted via 13-Hydroxylation pathway into GA20 and further converted into GA1 by 3-β-Hydroxylation

d) Hydroxylation at C-2 then converts GA4 and GA1 to the inactive forms GA34 and GA8, respectively
