[Post-transcriptional gene silencing and virus resistance].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2001
Post-transcriptional gene silencing(PTGS) is a defense mechanism of plants against foreign nucleic acids, such as virus infection. The mechanism results in sequence-specific degradation of nucleic acids, including endogenous mRNA, transgene mRNA and virus RNA.

Conservation of transgene-induced post-transcriptional gene silencing in plants and fungi

Trends in Plant Science, 1997
Different types of post-transcriptional transgene-induced gene silencing have been shown to occur in Neurospora (quelling) and plants (co-suppression). Common mechanistic features include triggering by duplicated coding sequences, simultaneous silencing of the transgene and endogenous genes, reversibility of silencing and post-transcriptional ...

Quelling: post-transcriptional gene silencing guided by small RNAs in Neurospora crassa

Current Opinion in Microbiology, 2007
The filamentous fungus Neurospora crassa is a model organism for the study of gene silencing. The most characterized gene silencing mechanism in this ascomycete is quelling, which occurs at the post-transcriptional level. Quelling is triggered by the introduction of transgenes and results in silencing of both transgenes and cognate endogenous mRNAs ...

Mechanistic characterization of post-transcriptional gene silencing

2007
With the ongoing task of identifying and characterizing genes in the human genome, there is a great demand for tools to study these genes. Today, reverse genetics is the most effective way to explore gene function. This involves suppression of the gene of interest by a set of manipulation techniques.

CHARACTERIZATION OF POST TRANSCRIPTIONAL GENE SILENCING SUPPRESSOR PROTEINS OF BENYVIRUS

2012
An innate mechanism that plants use to protect themselves against viral infections is called Post Transcriptional Gene Silencing (PTGS). PTGS is triggered by the presence of aberrant RNA or dsRNA generated during the replication of viral genomes and leads to their degradation. To counteract this innate mechanism, viruses co-evolved with their hosts and

Properties of post-transcriptional gene silencing suppression proteins of Benyviruses

2013
Beet necrotic yellow vein virus (BNYVV) and Beet soil-borne mosaic virus (BSBMV) belong to the Benyvirus genus, possess a multipartite genome formed by four ssRNAs(+) and are both transmitted by the plasmodiophorid Polymyxa betae. BSBMV and BNYVV are closely related since they possess the same host range, vector and genome organization.
