Phenotype
Defective in gibberellin 3-oxidase 1; involved in the production of bioactive GA for vegetative and reproductive growth and development; semi-dwarf plants with a 50% reduction in final height and a slightly reduced rosette size compared with wild type; roots are slightly shorter; germination percentages are similar to wild type in either the dark or the light; plants have the same number of leaves as wild type, but they flower 3 days later than wild type; no observable plant phenotype was noted in the flowers and the fertility (average number of seeds/silique on primary inflorescence stems). Relatively high levels of expression in all organs and stages of plant development; predominantly expressed in the stem, consistent with the requirement of bioactive GA for stem elongation and the semi-dwarf phenotype; expressed at relatively high levels in the cortex and endodermis of the embryo axis of germinating seeds; expressed in roots of 5-dayold seedlings; the bioactive level of GA4 in plants is decreased , while the level of GA9 is increased compared to wild type.
