The Charaterization of New Stem Length Mutants of Arabidopsis thaliana

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突变体。这项工作将描述一组突变体，这些突变体要么被外部遗传拯救，要么对外部遗传无反应。这项工作包括突变体的互补、基因的克隆和表征，以及基因合成途径中酶的生化表征，这些酶被突变体的表型行为表明可能存在缺陷。

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.
