    Comparison of three techniques for the detection of Grapevine leafroll-associated virus 1.

  • Original language description

    Thirty seven plants of grapevine from the Research Station of Viticulture, Karlštejn was examined for the presence of leafroll viruses. Grapevine leafroll-associated virus 1 (GLRaV-1) was detected in the grapevines plants tested using double-antibody sandwich ELISA (DAS-ELISA), RT-PCR and molecular hybridization with non-radioactive RNA probes. Both molecular methods were based on a detection of the GLRaV-1 heat-shock protein 70 (HSP70) gene and showed a higher sensitivity in the detection of GLRaV-1 compared to DAS-ELISA. RNA probes are considered more suitable for the GLRaV-1 detection, as their application can overcome potential minor sequence variability, which may cause the detection by RT-PCR less reliable, especially when the variability occursin the genome region targeted by RT-PCR primers. Based on additional DAS-ELISA, other viruses were detected, often in a mix infection: Grapevine leafroll-associated virus 3 (GLRaV-3), Grapevine virus A (GVA) and Grapevine fleck virus (GFk

    Porovnání tří technik pro detekci viru svinutky révy 1.

  • Czech description

    Třicet sedm rostlin révy vinné z Výzkumné stanice vinařské Karlštejn bylo testováno na přítomnost virů způsobujících svinutku révy vinné. Virus svinutky révy vinné 1 (GLRaV-1) byl prokázán v rostlinách révy vinné pomocí metod DAS-ELISA, RT-PCR a molekulární hybridizace s neradioaktivními RNA sondami. Obě použité molekulární metody, založené na detekci genu pro HSP70, prokázaly vyšší citlivost při detekci GLRaV-1 než DAS-ELISA. RNA sondy lze doporučit jako vhodnější metodu pro detekci tohoto viru, protože nejsou ovlivněny menšími změnami v sekvenci detekovaného viru, což by například při RT-PCR mohlo způsobit problémy, pokud by se taková změna vyskytla v oblasti primerů. V testovaných rostlinách byl pomocí DAS-ELISA dále prokázán výskyt viru svinutky révy vinné 3 (GLRaV-3), A viru révy vinné (GVA) a viru skvrnitosti révy vinné (GFkV). Tyto viry se často vyskytovaly ve směsné infekci.
