Meanwhile, MtGA2ox10 OE in the stable transgenic plants resulted in dwarfism with low fertility and inhibition of nodule development despite of increased root infection, presumably due to ectopic inactivation of earlier intermediate C20 GAs (GA12 and GA53) or disruption of the GA pool by altered expression of KS, KAO, GA13ox, and GA3ox. These results were consistent with the previous report from pea na-1 mutant5; therefore, clarified the role of GA on the different stages of nodulation (suppression of infection and activation of nodule formation). The gene discussed is AOC1; the disease is infection.
