    RNA-mediated trans-activation of transcription from a viral RNA (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-08-07
    Description: The red clover necrotic mosaic virus genome is composed of two single-stranded RNA components, RNA-1 and RNA-2. The viral capsid protein is translated from a subgenomic RNA (sgRNA) that is transcribed from genomic RNA-1. Here, a 34-nucleotide sequence in RNA-2 is shown to be required for transcription of sgRNA. Mutations that prevent base-pairing between the RNA-1 subgenomic promoter and the 34-nucleotide trans-activator prevent expression of a reporter gene. A model is proposed in which direct binding of RNA-2 to RNA-1 trans-activates sgRNA synthesis. This RNA-mediated regulation of transcription is unusual among RNA viruses, which typically rely on protein regulators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sit, T L -- Vaewhongs, A A -- Lommel, S A -- New York, N.Y. -- Science. 1998 Aug 7;281(5378):829-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Pathology, North Carolina State University, Raleigh, NC 27695-7616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9694655" target="_blank"〉PubMed〈/a〉

    THE MULTIFUNCTIONAL CAPSID PROTEINS OF PLANT RNA VIRUSES (2001)
    Palo Alto, Calif. : Annual Reviews

    Notes: Abstract This article summarizes studies of viral coat (capsid) proteins (CPs) of RNA plant viruses. In addition, we discuss and seek to interpret the knowledge accumulated to date. CPs are named for their primary function; to encapsidate viral genomic nucleic acids. However, encapsidation is only one feature of an extremely diverse array of structural, functional, and ecological roles played during viral infection and spread. Herein, we consider the evolution of viral CPs and their multitude of interactions with factors encoded by the virus, host plant, or viral vector (biological transmission agent) that influence the infection and epidemiological facets of plant disease. In addition, applications of today's understanding of CPs in the protection of crops from viral infection and use in the manufacture of valuable compounds are considered.
