V2 from a curtovirus is a suppressor of post-transcriptional gene silencing [PDF]

, 2017
The suppression of gene silencing is a key mechanism for the success of viral infection in plants. DNA viruses from the Geminiviridae family encode several proteins that suppress transcriptional and post-transcriptional gene silencing (TGS/PTGS).

A Genetic Screen for Impaired Systemic RNAi Highlights the Crucial Role of DICER-LIKE 2 [PDF]

, 2017
Posttranscriptional gene silencing (PTGS) of transgenes involves abundant 21-nucleotide small interfering RNAs (siRNAs) and low-abundance 22-nucleotide siRNAs produced from double-stranded RNA (dsRNA) by DCL4 and DCL2, respectively.

Cytoplasmic and nuclear quality control and turnover of single-stranded RNA modulate post-transcriptional gene silencing in plants

, 2013
Eukaryotic RNA quality control (RQC) uses both endonucleolytic and exonucleolytic degradation to eliminate dysfunctional RNAs. In addition, endogenous and exogenous RNAs are degraded through post-transcriptional gene silencing (PTGS), which is triggered ...

Scheduling in Heterogeneous Distributed Computing Systems Based on Internal Structure of Parallel Tasks Graphs with Meta-Heuristics

, 2020
The problem of scheduling parallel tasks graphs (PTGs) represented by directed acyclic graphs (DAGs) in heterogeneous distributed computing systems (HDCSs) is considered an nondeterministic polynomial time (NP) problem due to the diversity of ...

Study of the PTGS suppressor activity of V2 protein from geminivirus Beet curly top virus [PDF]

, 2017
Suppression of gene silencing is a key mechanism for the success of viral infection in plants. DNA viruses from the Geminiviridae family encode several proteins that suppress post- and transcriptional gene silencing (PTGS/TGS). In Begomovirus V2 has been

AS2 overexpression blocks PTGS in Arabidopsis.

, 2015
(A) The Arabidopsis L1 line (Col-0 background) carries a 35S:GUS that has been silenced by PTGS [24]. The L1 line was re-transformed with 35S: AS2 and 35S:AS2-YFP. Note the re-activation of GUS expression by 35S: AS2 and 35S:AS2-YFP. Bar = 10 mm. (B) GUS

Pharmacogenetics of the prostaglandin-endoperoxide synthase 2 (PTGS-2) 5' and 3' untranslated regions in three distinct Asian populations.

, 2011
Cyclooxygenase-2 (COX-2) is an enzyme induced in response to mitogens, tumour promoters, and cytokines. Gene expression of COX-2 is found to be upregulated in solid tumours.

Interactions spatiales entre infection virale et extinction post-transcriptionnelle naturelle chez le pétunia

, 2002
L'extinction post-transcriptionnelle (PTGS pour post-transcriptional gene silencing) est un mécanisme général de régulation de l'expression génique fondé sur la dégradation séquence-spécifique des ARN transcrits.

Viral interference with gene silencing in non-transgenic or transgenic plants

, 2001
Various agronomically interesting traits have been obtained by inducing post-transcriptional gene silencing (PTGS) in transgenic cultivated crops. Some plant cultivars that were created by interspecific crosses also display PTGS-induced phenotypes.
