[Effect of the lipopolysaccharide-protein complex of Pseudomonas syringae PV. atrofaciens on the process of tumor formation caused by Agrobacterium tumefaciens].
It has been found that the agent of bacterial spotting of rye P. syringae pv. atrofaciens 8281 has no antagonistic action on the strains 9052 and 9054 of Agrobacterium tumefaciens--the agent of crown gall tumor. Lipopolysaccharide-protein complex of P. syringae pv. atrofaciens 8281 when added to the culture medium does not affect the growth and development of A. tumefaciens bacteria. It has been experimentally established that the lipopolysaccharide-protein complex of P. syringae pv. atrofaciens 8281, when used to treat the potato explants before inoculation of A. tumefaciens, decreases induction and development of tumours on the explants. Tumour formation inhibition depends on concentration of lipopolysaccharide-protein complex solution.
