The effects of GA biosynthesis inhibitors on the vegetative growth of plants ectopically expressing the TPR domain of SPY. A, Map of the gene construct for overexpression the TPR domain of SPY. The components of the gene include the CaMV 35S promoter (CaMV 35S), the 5′-untranslated leader of SPY (Leader), the region of the SPY gene that encodes the TPR region (TPR Domain), a c-myc epitope tag (c-myc), and the nopaline synthase gene polyadenylation sequence (NOS). B, Three-week old plants of wild type, spy-3, and wild-type TPR-overexpressing line 7b8 were continuously grown in the presence of 10⁻⁷ m uniconazole.
