Analysis of the involvement of an inducible Arabidopsis RNA-dependent RNA polymerase in antiviral defense.
Roles of a newly identified Arabidopsis RdRP gene (AtRdRP1) in plant antiviral defense are analyzed and results suggest that the inducible AtRd RP1 is theArabidopsis ortholog of NtRdLP1 and plays a role in antiviraldefense.
Gene Silencing without DNA: RNA-Mediated Cross-Protection between Viruses
Analysis of plants infected with viruses that are quite distinct from the nepovirus or caulimovirus groups demonstrates that this RNA-mediated defense is a general response to virus infection, and provides direct evidence that post-transcriptional gene silencing of nuclear genes is a manifestation of a natural defense mechanism that is induced by a wide range of viruses.

This research presents a meta-anatomy of the immune response to central giant coronavirus, a model that has shown promise in understanding the immune system’s response to infectious disease.
Raspberry leaf blotch virus, a putative new member of the genus Emaravirus, encodes a novel genomic RNA.
Results suggest that the P4 protein may be a movement protein for RLBV, a new, segmented, negative-strand RNA virus discovered in raspberry plants exhibiting symptoms of leaf blotch disorder.
Virus-induced gene silencing as a tool for functional genomics in a legume species.
The results suggest that the PEBV vector can be applied to functional genomics in a legume species to study genes involved in a wide range of biological processes.
Cajal bodies and the nucleolus are required for a plant virus systemic infection
The ability of the groundnut rosette virus open reading frame (ORF) 3 protein to move viral RNA long distances through the phloem strictly depends on its interaction with CBs and the nucleolus.
Interaction of a plant virus-encoded protein with the major nucleolar protein fibrillarin is required for systemic virus infection
Previously undescribed functions for fibrillarin are demonstrated as an essential component of translocatable viral RNPs and may have implications for other plant and animal viruses that interact with the nucleolus.
Functional replacement of the tobacco rattle virus cysteine-rich protein by pathogenicity proteins from unrelated plant viruses.
Mutation of the 16K gene could be overcome by expression from RNA2 of the Cucumber mosaic virus 2b gene, the Soil-borne wheat mosaic virus 19K gene, or the Barley stripe mosaic virus gammab gene, indicating that the proteins encoded by these diverse genes may have similar functions.
Viruses and Virus Diseases of Rubus.
The goals of this article are to update the knowledge on previously characterized viruses of Rubus, highlight recently described viruses, review the virus-induced symptoms, describe the advances made in their detection, and discuss the knowledge about several virus complexes that cause serious diseases in Rubus.
Relocalization of Nuclear ALY Proteins to the Cytoplasm by the Tomato Bushy Stunt Virus P19 Pathogenicity Protein1[w]
It is reported that P19 interacts with the conserved RNA-binding domain of an as yet uncharacterized family of plant ALY proteins that, in animals, are involved in export of RNAs from the nucleus and transcriptional coactivation.
