RNA silencing and antiviral defense in plants
Current Opinion in Plant Biology, 2005Much progress has been made recently in identifying the molecular components of RNA silencing in plants, and in understanding their roles in the biogenesis of small interfering RNAs and microRNAs, in RNA-directed DNA methylation, and in RNA-mediated antiviral defense. However, many crucial questions remain unanswered.

RNA Silencing in Plants--Defense and Counterdefense
Science, 2001RNA silencing is a remarkable type of gene regulation based on sequence-specific targeting and degradation of RNA. The term encompasses related pathways found in a broad range of eukaryotic organisms, including fungi, plants, and animals. In plants, it serves as an antiviral defense, and many plant viruses encode suppressors of silencing.

A Partial Defense of Illocutionary Silencing
Hypatia, 2011Catharine MacKinnon has pioneered a new brand of anti-pornography argument. In particular, MacKinnon claims that pornography silences women in a way that violates their right to free speech. In what follows, we focus on a certain account of silencing put forward by Jennifer Hornsby and Rae Langton, and we defend that account against two important ...

Workplace bullying and employee silence
Personnel Review, 2018 Purpose The purpose of this paper is to examine the effects of workplace bullying on employee silence (defensive, relational, and ineffectual silence), and to test the mediating role of psychological contract violation (PCV) in this relationship and the

A Similarity Between Viral Defense and Gene Silencing in Plants
Science, 1997Gene silencing in plants, in which an endogenous gene is suppressed by introduction of a related transgene, has been used for crop improvement. Observations that viruses are potentially both initiators and targets of gene silencing suggested that this phenomenon may be related to natural defense against viruses.

piRNA-Guided Genome Defense: From Biogenesis to Silencing
Annual Review of Genetics, 2018PIWI-interacting RNAs (piRNAs) and their associated PIWI clade Argonaute proteins constitute the core of the piRNA pathway. In gonadal cells, this conserved pathway is crucial for genome defense, and its main function is to silence transposable elements. This is achieved through posttranscriptional and transcriptional gene silencing.

Post-transcriptional gene-silencing: RNAs on the attack or on the defense?
BioEssays, 2000Post-transcriptional gene-silencing (PTGS) was first discovered in plants and results from the sequence-specific degradation of RNA. Degradation can be activated by introducing transgenes, RNA viruses or DNA sequences that are homologous to expressed genes. A similar RNA degradation mechanism which is inducible by double-stranded RNA (dsRNAs), has been

Silencing the Jasmonate Cascade: Induced Plant Defenses and Insect Populations
Science, 2004We transformed the native tobacco, Nicotiana attenuata , to silence its lipoxygenase, hydroperoxide lyase, and allene oxide synthase genes in order to inhibit oxylipin signaling, known to mediate the plant's direct and indirect defenses.

Women's Justice: Alan's Wife and the Defense of Silence
Victorian Studies, 2023Abstract: Elizabeth Robins and Florence Bell's Alan's Wife (1893) shocked its first audiences with the brutality of the piece, but the play holds greater historical interest for its fusion of nineteenth-century theatrical approaches. The Naturalism associated with the independent theater movement is apparent in the debates about eugenics, capital ...

How to Silence One’s Conscience: Cognitive Defenses Against the Feeling of Guilt
Journal for the Theory of Social Behaviour, 1998This work presents an analysis of the feeling of guilt and in particular of the cognitive defenses against it. It shows how the need to avoid or mitigate the feeling, with the suffering implied, affects the perception and judgment of oneself and others.
