Long non-coding RNA transcripts response to light


Recent research on long noncoding RNAs (lncRNAs) has expanded our understanding of gene transcription regulation and the generation of cellular complexity. Depending on their genomic origins, lncRNAs can be transcribed from intergenic or intragenic regions or from introns of protein coding genes. Researchers at Rockefeller University have recently reported more than 6,000 intergenic lncRNAs in Arabidopsis. Here, they systematically identified long ...

Analysis of long non-coding RNAs produced by a specialized RNA Polymerase in Arabidopsis thaliana

Long non-coding RNAs (lncRNAs) play important roles in several processes including control of gene expression. In Arabidopsis thaliana, a class of lncRNAs is produced by a specialized RNA Polymerase V (Pol V), which is involved in controlling genome activity by transcriptional gene silencing. lncRNAs produced by Pol V have been proposed to serve as scaffolds for binding of several silencing ...

Wide-spread long non-coding RNAs (lncRNAs) as endogenous target mimics (eTMs) for microRNAs in plants

Target mimicry is a recently identified regulatory mechanism for microRNA functions in plants in which the decoy RNAs bind to microRNAs via sequence complementary therefore to block the interaction between microRNAs and their authentic targets. Both endogenous decoy RNAs (microRNA target mimics) and engineered artificial RNAs can induce target mimicry effects. Yet until now, only the IPS1 (Induced by Phosphate ...
