| Outline of Final Research Achievements |
The moss Physcomitrella patens has a partial biosynthetic pathway for gibberellin and produces an intermediate, ent-kaurenoic acid (KA). Protonemal cell differentiation is incomplete under KA-deficiency and restored by KA application but not by gibberellin. Herein, two KA-metabolites, ent-3β-hydroxy-kaurenoic acid and ent-2α-hydroxy-kaurenoic acid were identified. The oxidation of KA at the C-3/C-2 position determines the activation or inactivation of the KA-metabolism, which appears to be an ancient type of gibberellin regulation.
