Post-transcriptional gene silencing is an RNA degradation mechanism that can be induced by viruses. Recent evidence indicates that silencing may also be involved in virus synergism, tissue limitation of virus spread, non-host resistance, virus transmission through seeds and in more general mechanisms of defense such as that mediated by salicylic acid ...

Journal of Virology, 1977
Visna is a classical slow infection in which virus characteristically persists in the face of the host immune response. The agent of this disease belongs to the retravirus group. The persistence of infection and the slow spread of virus are at least in part a consequence of restriction of the expression of virus genetic information in tissues of an ...

RVvictor: Virus RNA-directed molecular interactions for RNA virus infection
Computers in Biology and MedicineRNA viruses are major human pathogens that cause seasonal epidemics and occasional pandemic outbreaks. Due to the nature of their RNA genomes, it is anticipated that virus's RNA interacts with host protein (INTPRO), messenger RNA (INTmRNA), and non-coding RNA (INTncRNA) to perform their particular functions during their transcription and replication ...

RNA virus discovery in insects
Current Opinion in Insect Science, 2015The advent of next generation sequencing (NGS) technology has allowed for significant advances in insect RNA virus discovery, particularly for identification of covert viruses and for identification of previously undescribed virus groups. Recent research has revealed the complexity and diversity both of viral populations within an insect, and of ...

RNA viruses are the most common viruses of plants, and the evolution of these viruses has been studied both experimentally and phylogenetically. The basic molecular mechanisms for plant virus evolution are similar to those of other viruses, with some notable exceptions. Recent advances include new insights into the origins of plant viruses, analyses of

RNA composition of Junin virus
Journal of Virology, 1976Junin virus grown in BHK-21 cells was labeled with [3H]uridine and highly purified by differential and isopycnic centrifugation. The RNAs extracted with phenol and analyzed by polyacrylamide gel electrophoresis were shown to be composed of four large species (33, 28, and 18S) and three small ones (4, 5, and 5.5S).

Prisoner's dilemma in an RNA virus
Nature, 1999The evolution of competitive interactions among viruses was studied in the RNA phage phi6 at high and low multiplicities of infection (that is, at high and low ratios of infecting phage to host cells). At high multiplicities, many phage infect and reproduce in the same host cell, whereas at low multiplicities the viruses reproduce mainly as clones.

Oligonucleotide Fingerprinting With RNA Tumor Virus RNA
1978Recent advances in characterizing the genomic structure of RNA tumor viruses have been made by oligonucleotide fingerprinting of the viral RNA. With this sequencing technique, genetic relationships between viruses have been determined, the viral genome has been sized and mapped, and recombination has been studied.

The characterization of Chikungunya virus RNA
Archiv f�r die gesamte Virusforschung, 1972Highly purified preparations of Chikungunya virus (CHV) were obtained from culture fluid of infected VERO cells (Green monkey kidney stable cells) by differential centrifugation involving sedimentation through 25% sucrose solution and density gradient centrifugation by the use of potassium tartrate (17 to 27 %).
