Publisher Summary It is clear from the experimental data that there are some similarities in
RNA replication for all eukaryotic positive-stranded RNA viruses—that is, the mechanism of …

▪ 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 …

Posttranscriptional gene silencing (PTGS) processes double‐stranded (ds) RNAs into 21–
25 nucleotide (nt) RNA fragments that direct ribonucleases to target cognate mRNAs. In …

Temperature dramatically affects plant–virus interactions. Outbreaks of virus diseases are
frequently associated with low temperature, while at high temperature viral symptoms are …

RNA silencing in plants likely exists as a defense mechanism against molecular parasites
such as RNA viruses, retrotransposons, and transgenes. As a result, many plant viruses …

RNA silencing is an evolutionarily conserved surveillance system that occurs in a broad
range of eukaryotic organisms. In plants, RNA silencing acts as an antiviral system; thus …

ABSTRACT RNA silencing is conserved in a broad range of eukaryotes and includes the
phenomena of RNA interference in animals and posttranscriptional gene silencing (PTGS) …

▪ Abstract Although many subviral RNAs reduce or intensify disease symptoms caused by
the helper virus, only recently have clues concerning the mechanism of disease modulation …

Post-transcriptional gene silencing (PTGS) is a sequence-specific degradation mechanism
that operates in almost all eukaryotic cells. In plants, double-stranded RNA triggers PTGS …

The tombusviruses are among the most extensively studied messenger-sensed RNA plant
viruses. Over the past decade, there have been numerous important advances in our …
