An antiviral RISC isolated from Tobacco rattle virus-infected plants.
The RNAi model predicts that during antiviral defense a RNA-induced silencing complex (RISC) is programmed with viral short-interfering RNAs (siRNAs) to target the cognate viral RNA for degradation. We show that infection of Nicotiana benthamiana with Tobacco rattle virus (TRV) activates an antiviral nuclease that specifically cleaves TRV RNA in vitro. In agreement with known RISC properties, t...
متن کاملInvestigation of Tobacco rattle virus infection in peonies (Paeonia L.)
The aim of this study was to evaluate the occurrence of peony ring spot disease in the collections of foreign and Lithuanian origin peony cultivars and hybrids and to identify a causal agent of this viral disease. During surveys of ornamental plant collections grown in Lithuania, solitary instances of affected by peony ring spot disease plants have been detected in all collections surveyed. Dis...
متن کاملInactivation and mutagenesis of tobacco rattle virus by nitrous acid.
The rate of inactivation of tobacco rattle virus RNA by o.z M-nitrous acid at pH 4"o was comparable to that of tobacco mosaic virus RNA. In o'o025 M-nitrous acid at pH 6.0 this rate was greatly diminished, and was slower than that of intact virus. Possible reasons for this are discussed. Methods are described for the induction of mutants of tobacco rattle virus by nitrous acid, and for the sele...
متن کاملImmunogold Localization of Tobacco Rattle Virus Particles within Paratrichodorus anemones.
Unequivocal evidence of the viral nature of virus-like particles observed at the specific site of retention of tobacco rattle virus (TRV) in Paratrichodorus and Trichodorus nematodes has not previously been available. A new staining technique using safranin-O, which does not affect viral antigenicity, was used with an antiserum raised against the coat protein of TRV and prepared for use with im...

ABBTRACT Thi 3' terainal forty nucleotides of tobraviral RNAs readily fold into a tertiary structure, reseabling that of tyaoand tobaaoviral RNAs. The latttr RNA* possess a tRNA-like structure at their 3' m d that is recognized by a nUBber of tRNA-specific enzyaes (Rietveld et al. (1984), EHBO J. 2, 26132619).
