dc.description.abstract | Shoots of micropropagated Gentiana acaulis, G. cruciata, G. lutea, and G. purpurea were inoculated with suspensions of Agrobacterium rhizogenes cells, strains ATCC 15834 or A4M70GUS. Adventitious roots appeared at the sites of inoculation in all 4 species. Root tips were excised and cultured on growth regulator-free media for 2-6 years. They exhibited very high branching and plagiotropism. Spontaneous bud initiation occurred in roots of G. cruciata. Roots of G. lutea, G. acaulis and G. purpurea were cultured on media with high kinetin concentration, which induced the formation of friable callus tissues. Only in G. purpurea were these calluses organogenic. Regenerated shoots of G. cruciata and G. purpurea gave rise to plants, that displayed the typical phenotypes of A. rhizogenes-transformed plants: short internodes and rolled leaves. In the roots of G. acaulis and G. cruciata, transformed with A. rhizogenes A4M70GUS, a positive reaction with X-gluc indicated the activity of beta-glucuronidase. The DNA extracted from hairy roots and from the roots of transgenic plants hybridized with the appropriate genomic probes in Southern blotting. This is taken as evidence of the stable genetic transformation in the 4 Gentiana species. | en |
