The Charaterization of New Stem Length Mutants of Arabidopsis thaliana

9723890海绵起源于一群对脱落酸不敏感的突变体，诱变产生了对赤霉素不敏感的茎长矮秆突变体。这项工作将描述一组突变的特征，这些突变要么被外部遗传算法拯救，要么对外部遗传算法没有反应。这项工作包括突变互补，基因克隆和鉴定，以及GA生物合成途径中的酶的生化表征，这些酶被突变植物的表型行为表明是潜在的缺陷。

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.
