9723890 Sponsel Originating from a population of ABA-insensitive mutant, mutagenesis has produced stem-length dwarf mutants that are unresponsive to gibberellins. The work will characterize a group of mutants which are either rescued by external GA, or are unresponsive to external GA. This work includes mutant complementation, gene cloning and characterization, and biochemical characterization of enzymes in the GA biosynthesis pathway which are indicated as potentially defective by the phenotypic behavior of the mutant plants.

9723890 Sponsel来源于ABA不敏感突变体群体，诱变产生了对赤霉素无反应的茎长矮化突变体。 这项工作将表征一组突变体，这些突变体要么被外部GA拯救，要么对外部GA无反应。 这项工作包括突变体互补，基因克隆和表征，和生化特性的酶在GA生物合成途径中，这是表示为潜在的缺陷的突变体植物的表型行为。
