Anotace
Effects of the superinfection with tobacco mosaic virus (TMV) on susceptible tobacco plants infected with potato virus Y (PVY) were determined. Dynamic changes in the TMV and/or PVY contents, the ribonucleases (RNases), the phosphomonoesterase (PME), the phosphodiesterase (PDE) and the glucose-6-phosphate dehydrogenase (G6P DH) activities were studied. The PVY infection caused a substantial reduction in TMV multiplication. TMV enhanced the content of inducing virus (PVY) in the locally inoculated leaves, but reduced in the PVY systemically infected leaves. The activities of RNase, PME, PDE and G6P DH were increased (when compared with healthy plants) during the acute phase of single virus multiplication. The increase in the enzymes in mixed infection was at least as high as the sum of the increases of single infections.
