| Abstract:
The reaction of the transgenic plum pox virus (PPV) resistant C-5 plum was studied under conditions of co-infection with Prunus necrotic ringspot virus (PNRSV) and PPV as may be encountered in the field. C-5 and controls were inoculated with PPV and PNRSV following several co-infection schemes. The results of this preliminary study showed that, as expected, the transgenic clones, including C-5 were not resistant to PNRSV. Furthermore, no PPV resistance breaking effects of the two viruses co-existing in C-5 were observed. In the susceptible clones, the data suggest that PNRSV infection might mask some symptoms of sharka disease (PPV). These synergistic effects are under investigation. | |
