These physiological functions and fruit development [3,4]. The endogenous biosynthesis and catabolism of gibber-ellins within plants, as well as the gibberellin response pathway, have been described in detail previously [5-13]. In brief, gibberellin biosynthesis in higher plants can be divided into three stages (Figure 1A): (1) production of ent-kaurene in proplastids; (2) conversion of ent-kaurene to GA12 via microsomal cytochrome P450 monooxy-genases; and (3) formation of C20- and C19−GAs in the cytoplasm [3,14]. Following its biosynthesis, gibberelli
