Introns of plant pri - miRNAs enhance miRNA biogenesis and function
As you will see, all referees acknowledge that the findings are potentially interesting and suitable for publication in EMBO reports. However, both referees 1 and 2 point out that the observed effect of introns on enhancing mature miR163 levels should be extended to other miRNAs. Both referees also mention the inconsistency between your study and the one from Voinnet's lab regarding the require...
متن کاملIntrons of plant pri-miRNAs enhance miRNA biogenesis
Plant MIR genes are independent transcription units that encode long primary miRNA precursors, which usually contain introns. For two miRNA genes, MIR163 and MIR161, we show that introns are crucial for the accumulation of proper levels of mature miRNA. Removal of the intron in both cases led to a drop-off in the level of mature miRNAs. We demonstrate that the stimulating effects of the intron ...
متن کاملmiRNAs on the move: miRNA biogenesis and the RNAi machinery.
Recent advances have led to a more detailed understanding of RNA interference and its role in microRNA biogenesis and function. Primary microRNA transcripts are processed by the RNaseIII nuclease, Drosha, and are exported from the nucleus by Exportin-5. Dicer cleaves microRNAs into their mature forms, which can be incorporated into effector complexes that mediate gene silencing activities. The ...
متن کاملBiogenesis and the regulation of the maturation of miRNAs.
Regulation of gene expression is a fundamental process in both prokaryotic and eukaryotic organisms. Multiple regulatory mechanisms are in place to control gene expression at the level of transcription, post-transcription and post-translation to maintain optimal RNA and protein expressions in cells. miRNAs (microRNAs) are abundant short 21-23 nt non-coding RNAs that are key regulators of virtua...
متن کاملReconstituting plant miRNA biogenesis.
T he genomes of higher eukaryotes encode not only proteins but also diverse noncoding RNAs, particularly small (20to 30-nt) regulatory RNAs (1–3). The small RNAs include microRNAs (miRNAs), siRNAs, and piwi-interacting RNAs (piRNAs) (4, 5). These small RNAs repress gene expression at the transcriptional or posttranscriptional levels and have critical functions in genome defense, growth, develop...
