GA Biosynthetic and Catobolic Pathways in Plants. Adapted from Yamaguchi, 2008: reprinted, with permission, from the Annual Review of Plant Biology, Vol. 59 ©2008 by Annual Reviews, www.annualreviews.org.
(A) Synthesis of GA12 from GGDP.
(B) GA biosynthesis and deactivation (by GA2ox) pathways from GA12. The three active GAs are highlighted in grey circles. GA7 (13-nonhydroxy GA3), another active GA, is synthesized from GA9 (not shown).
