Overexpression of a Novel Class of Gibberellin 2-Oxidases Decreases Gibberellin Levels and Creates Dwarf Plants

Degradation of active C(19)-gibberellins (GAs) by dioxygenases through 2β-hydroxylation yields inactive GA products. We identified two genes in Arabidopsis (AtGA2ox7 and AtGA2ox8), using an activation-tagging mutant screen, that encode 2β-hydroxylases. GA levels in both activation-tagged lines were...
