Simultaneous detection of six viruses of tomato

Studies have been carried out in Spain to develop a polyprobe for the simultaneous detection by molecular hybridization of six tomato viruses which can occur in single or multiple infections in commercial crops:
- Cucumber mosaic virus (Cucumovirus, CMV),
- Parietaria mottle virus (Ilarvirus, PMoV),
- Pepino mosaic virus (Potexvirus, PepMV – EPPO Alert List),
- Potato Y virus (Potyvirus, PVY),
- Tomato mosaic virus (Tobamovirus, ToMV),
- Tomato spotted wilt virus (Tospovirus, TSWV – EPPO A2 List).
The sensitivity and specificity of the polyprobe were found equivalent to those of individual probes. The polyprobe could also be used in combination with tissue-printing as a sample preparation technique. The authors concluded that this new method (polyprobe/tissue printing) could be a useful tool for the routine screening to tomato plants to verify the presence of these viruses (alone or in combination).
