Enhancement of post-transcriptional gene silencing by grafting [PDF]
We showed previously that grafting transmitted silencing occurred when transgenic ACC oxidase 1 (ACO1) overexpressing tomato plants that also produced siRNAs were grafted onto transgenic stocks that already showed strong silencing. The presence of siRNAs in these overexpressing scions may indicate that silencing, though inefficient, may already occur ...

The Whys and Wherefores of Transitivity in Plants
Transitivity in plants is a mechanism that produces secondary small interfering RNAs (siRNAs) from a transcript targeted by primary small RNAs (sRNAs). It expands the silencing signal to additional sequences of the transcript.

Epigenetic silencing in transgenic plants
Epigenetic silencing is a natural phenomenon in which the expression of gene is regulated through modifications of DNA, RNA or histone proteins. It is a mechanism for defending host genomes against the effects of transposable element, viral infection and

Assessment of RNAi-induced silencing in banana (Musa spp.) [PDF]
In plants, RNA- based gene silencing mediated by small RNAs functions at the transcriptional or post-transcriptional level to negatively regulate target genes, repetitive sequences, viral RNAs and/or transposon elements.

Traffic into silence: endomembranes and post-transcriptional RNA silencing. [PDF]
microRNAs (miRNAs) and small interfering RNAs (siRNAs) are small RNAs that repress gene expression at the post-transcriptional level in plants and animals. Small RNAs guide Argonaute-containing RNA-induced silencing complexes to target RNAs in a sequence-

FXN promoter silencing in the humanized mouse model of Friedreich Ataxia [PDF]
Background - Friedreich ataxia is caused by an expanded GAA triplet-repeat sequence in intron 1 of the FXN gene that results in epigenetic silencing of the FXN promoter.

Enhancement of Recombinant Protein Production in Transgenic Nicotiana benthamiana Plant Cell Suspension Cultures with Co-Cultivation of Agrobacterium Containing Silencing Suppressors. [PDF]
We have previously demonstrated that the inducible plant viral vector (CMViva) in transgenic plant cell cultures can significantly improve the productivity of extracellular functional recombinant human alpha-1-antiryspin (rAAT) compared with either a ...

Post-Transcriptional Gene Silencing in Cultured Rice Cells [PDF]
Post-transcriptional gene silencing (PTGS) has been shown to occur in many transgenic dicotyledonous plants. Although transgene silencing has been documented in transgenic monocots, PTGS has been only recently described in monocotyledonous plants. To study PTGS in rice, we generated 25 transgenic rice cell lines in which the 35S-gus gene was stably ...

Internuclear gene silencing in Phytophthora infestans is established through chromatin remodelling [PDF]
In the plant pathogen Phytophthora infestans, nuclear integration of inf1 transgenic DNA sequences results in internuclear gene silencing of inf1. Although silencing is regulated at the transcriptional level, it also affects transcription from other ...

Post-transcriptional gene silencing: Basic concepts and applications
Post-transcriptional gene silencing (PTGS)-mediated gene silencing exploits the cellular mechanism wherein transcripts having sequence similarity to the double-stranded RNA (dsRNA) molecules present in the cell will be subjected to degradation. PTGS is closely related to natural processes such as RNA-mediated virus resistance and cross-protection in ...
