Abstract: | A method is described for producing genetically transformed plants from explants of three scentedPelargonium spp. Transgenic hairy root lines were developed fromPelargonium spp leaf explants and microcuttings after inoculation withAgrobacterium rhizogenes strains derived from the agropine A4 strain. Hairy root lines grew prolifically on growth regulator-free medium. Transgenic shoots were regenerated from hairy roots and the plants have been successfully transferred to soil. The phenotype of regenerated plants has been characterized as having abundant root development, more leaves and internodes than the controls, short internodes and highly branched roots and aerial parts. Southern blot analyses have confirmed the transgenic nature of these plants. |
