A previously unknown biologically active gibberellin present in seeds of Arabidopsis thaliana is formed by hydration of the gibberellin precursor GA12 through the action of GAS2, a 2-oxoglutarate-dependent dioxygenase that decreases sensitivity to abscisic acid and promotes seed germination and seedling establishment.
