    Dániel Silhavy
    Agricultural Biotechnology Center, Plant Biology Institute, PO Box 411, H 2101, Godollo, Hungary
    EMBO J 21:3070-80. 2002
    ..Moreover, the observation that p19-expressing transgenic plants show altered leaf morphology might indicate that the p19-targeted PTGS pathway is also important in the regulation of plant development...
  2. ncbi Aureusvirus P14 is an efficient RNA silencing suppressor that binds double-stranded RNAs without size specificity
    Zsuzsanna Mérai
    Agricultural Biotechnology Center, Plant Science Institute, P O Box 411, H 2101 Gödöllõ, Hungary
    J Virol 79:7217-26. 2005
    ..Finally, sequence analyses suggest that P14 and P19 suppressors diverged from an ancient dsRNA binding suppressor that evolved as a nested protein within the common ancestor of aureusvirus-tombusvirus movement proteins...
  3. ncbi Short defective interfering RNAs of tombusviruses are not targeted but trigger post-transcriptional gene silencing against their helper virus
    Gyorgy Szittya
    Agricultural Biotechnology Center, Plant Biology Institute, P O Box 411, H 2101 Gödöllõ, Hungary
    Plant Cell 14:359-72. 2002
    ..Because PTGS operates in a wide variety of different organisms, this model is applicable to DI RNA generation and accumulation in both plant and animal cells...
  4. ncbi Double-stranded RNA binding may be a general plant RNA viral strategy to suppress RNA silencing
    Zsuzsanna Mérai
    Agricultural Biotechnology Center, H 2101 Gödöllõ, P O Box 411, Hungary
    J Virol 80:5747-56. 2006
    ..The findings that many unrelated silencing suppressors bind dsRNA suggest that dsRNA binding is a general silencing suppression strategy which has evolved independently many times...
  5. ncbi Effects and side-effects of viral RNA silencing suppressors on short RNAs
    Dániel Silhavy
    Agricultural Biotechnology Center, Plant Biology, PO Box 411, H 2101, Godollo, Hungary
    Trends Plant Sci 9:76-83. 2004
    ..Thus, suppressors contribute to viral symptoms. These findings fuel further research to test whether certain symptoms caused by animal viruses are also manifestations of altered RNA regulatory pathways...

    Gyorgy Szittya
    Agricultural Biotechnology Center, Plant Biology, PO Box 411, H 2101, Godollo, Hungary
    EMBO J 22:633-40. 2003
    ..However, temperature does not influence the accumulation of micro (mi) RNAs, which play a role in developmental regulation, suggesting that the two classes of small (si and mi) RNAs are generated by different nuclease complexes...

    Gyorgy Szittya
    Agricultural Biotechnology Center, Plant Science Institute, PO Box 411, 2101 Gödöllö, Hungary
    J Gen Virol 83:1505-10. 2002

    Sándor Kertész
    Agricultural Biotechnology Center, Godollo, Hungary
    Nucleic Acids Res 34:6147-57. 2006
    ..We have also identified plant UPF1 and showed that tethering of UPF1 to either the 5'- or 3'-UTR of an mRNA results in reduced transcript accumulation. Thus, plant UPF1 might bind to mRNA in a late, irreversible phase of NMD...

    Plant Mol Biol 75:277-90. 2011

    Lóránt Lakatos
    Agricultural Biotechnology Center, Plant Biology Institute, Gödöll, Hungary
