Abstract
Kanamycin resistance gene was introduced into tobacco and Atropa belladonna cells by binary vectors, based on Agrobacterium, by means of inoculation of seedlings. The plasmid pGA472, which carries chimaeric kanamycin resistance gene expressed in plants was introduced by transformation into A. tumefaciens Bo542, harbouring pTiBo542 plasmid and A. rhizogenes 8196, carrying pRi8196 plasmids and the resulting two strains were used as binary vectors. Tobacco tumors induced by A. tumefaciens Bo542(pGA472) grew as undifferentiated, kanamycin resistant tissues. Those induced by A. rhizogenes 8196(pGA472) differentiated into transformed plants. When cultivated in vitro on 200 μg ml-1 kanamycin medium, they showed yellow green sectoring, which was not selected out during vegetative propagation. Atropa belladonna tissues transformed by both A. tumefaciens Bo542(pGA472) and A. rhizogenes 8196(pGA472) differentiated plants which grew well on 200 μg ml-1 kanamycin as green, non-sectoring plants; sensitive cells obviously did not divide at all. Selection of Atropa belladonna transformed tissues on kanamycin medium is much more efficient than selection of transformed tobacco tissues with introduced kanamycin resistance gene.
