Posttranscriptional gene silencing is a defense mechanism in plants that is similar to
quelling in fungi and RNA interference in animals. Here, we describe four genetic loci that …

In plants and fungi, the introduction of transgenes can lead to post-transcriptional gene
silencing,. This phenomenon, in which expression of the transgene and of endogenous …

Introduction of transgene DNA may lead to specific degradation of RNAs that are
homologous to the transgene transcribed sequence through phenomena named post …

Posttranscriptional gene silencing (PTGS) in plants results from the degradation of mRNAs
and shows phenomenological similarities with quelling in fungi and RNAi in animals. Here …

Post-transcriptional gene silencing (PTGS) in plants is an RNA-degradation mechanism that
shows similarities to RNA interference (RNAi) in animals. Indeed, both involve double …

A mutation that disrupts post-transcriptional gene silencing in Neurospora crassa has been
found to affect the homologue of a plant-encoded RNA-dependent RNA polymerase. This …

Two distinct gene-silencing phenomena are observed in plants: transcriptional gene
silencing (TGS), which involves decreased RNA synthesis because of promoter methylation …

Overexpression of chimeric transgenes in plants can trigger post-transcriptional gene
silencing that is dependent on epigenetic information and physiological conditions. The …

The silencing phenotype in Arabidopsis thaliana lines with an inverted repeat transgene
under the control of a phloem-specific promoter was manifested in regions around veins due …

Small RNA molecules have been found to be specifically associated with posttranscriptional
gene silencing (PTGS) in both plants and animals. Here, we find that small sense and …
