Fig. 7. Updated GA metabolism in developing seeds/silique of Arabidopsis.
CYP72A is highlighted in red. The arrow between GA19 and GA20 (in Arabidopsis pathway) is thinner than the others to show the low catalytic efficiency of this reaction in Arabidopsis, at least in developing seeds/silique. Uncharacterized oxidase(s) catalyzed the conversion from GA34 to GA8.
