Using the gibberellin (GA) biosynthetic inhibitor Uniconazol, we determined that det1, a mutant that no longer requires light to be germinated, still requires GA synthesis for germination. This result suggests that dark inhibition of germination in Arabidopsis may be due to inhibition of GA synthesis by the DET1 gene product in mature wild-type seeds. Similar experiments with mutants that lack seed dormancy due to a reduced sensitivity to abscisic acid (abi) have shown that abi1 and abi3 no… CONTINUE READING
