Reduced internode length and increased branching in Pelargonium zonale pSAG12::ipt transgenic plants. (a-b). Constitutive GUS expression in leaf, stem and root fragments in the pSAG12::ipt transgenic plants as additional proof of their genetic transformation. (c-d). Non-transformed WT potted plant (left) compared with a pSAG12::ipt transgenic plant (right). The transgenic plant showed delayed leaf senescence, more evident in the basal leaves and increased branching. (e-f). The pSAG12::ipt stems showed reduced internodal length (right) when compared with control WT plants. (g). Statistical analysis of the important differences in internodal length among 6 WT plants and 6 transgenic lines. The transgenic pSAG12::ipt plants showed a more compact architecture that the WT phenotype. Bars: 1 cm.
