A DNA probe mix for the multiplex detection of ten artichoke viruses

Artichoke Italian latent virus (AILV), Artichoke latent virus (ArLV), Artichoke mottled crinkle virus (AMCV), Bean yellow mosaic virus (BYMV), Cucumber mosaic virus (CMV), Pelargonium zonate spot virus (PZSV), Tomato infectious chlorosis virus (TICV), Tobacco mosaic virus (TMV), Tomato spotted wilt virus (TSWV) and Turnip mosaic virus (TuMV) are damaging to artichoke. We have developed a protocol enabling the simultaneous detection of these artichoke viruses by non-isotopic dot blot hybridisation with DNA probes. The probe mix detected all viruses with high specificity and identical to that obtained using individual probes. The approach is proposed for the routine assessment of phytosanitary status for certified nursery production of globe artichoke.
