), of which only the rol genes, open reading frames 10 (rolA), 11 (rolB), 12 (rolC), and 15 (rolD), have been implicated in the establishment of the “ hairy root ” syndrome and studied to a certain extent (White et al. ; Spena et al. ). Although this syndrome is caused by their synergistic action, the rol genes . The rest of the group of seven (23%) in this action was completely helpless. The arithmetic mean of the study group for the actions become the object was points. This means that on average, for each child falls points. The arithmetic mean of the study group for using the skills of becoming an adult was points, ie. We report that the plant oncoprotein RolA from Agrobacterium rhizogenes acts to stabilize β- glucoronidase (Gus) when the two proteins are expressed as a fusion protein in transformed tobacco. The observed fold increase of Gus activity was shown to be related to protein accumulation, with no significant changes in.
