[Chromosome variability in grape (Vitis amurensis Rupr.) cells transformed with plant oncogene rolB].
The numbers of chromosomes and nucleoli in cultured cells of Vitis amurensis transformed with the rolB oncogene from A. rhizogenes have been studied. In general, the integration of the rolB gene in grape DNA mostly caused the elevation of the level of the chromosome variability, as well as higher numbers of nucleoli in the cultured cells. The possible influence of the observed chromosomal modifications on the productivity parameters of the grape cell cultures is discussed.
