Project description:nanoPARE: Parallel analysis of RNA 5' ends from low input RNA
| PRJNA449355 | ENA
Project description:A diversity of RNA molecule 5' ends are generated during transcriptional and post-transcriptional processes. Different RNA ends can confer or represent different functional activities and thus the identification of RNA end usage dynamics contributes to the functional characterization of RNA molecules. Here we present a method that enables the accurate identification of RNA 5' ends from samples with low amounts of total RNAs, and thus allow characterization of RNA regulatory mechanisms in specific cell-types.

Project description:5′ RNA ligase mediated rapid amplification of cDNA ends (5′ RLM-RACE) is the widely used tool for confirming the direct cleavage of target mRNA by a miRNA. Recently, 5′ RLM-RACE combined with high-throughput sequencing such as parallel analysis of RNA ends (PARE) are gaining importance as these techniques allows to assess the large number of sample in a single experiment. In order to verify the cleavage of predicted a target mRNA in potato spindle tuber viroid (PSTVd) infected tomato plants, the the leaf samples collected from the mock inoculated (control/healthy) at 21-days were subjected for RNA extraction. A custom RNA adaptor containing MmeI restriction endonuclease was ligated to the free 5'-phosphate end of an uncapped mRNA using T4 RNA ligase, followed by reverse transcription (RT) and second strand synthesis using poly (T) primers. Obtained product was slightly amplified, cleaved with MmeI restriction endonuclease and then, a dsDNA adaptor was added to the 3’-end of the MmeI restriction endonuclease cleavage site. Resulted products were sequence in an Illumina Mi-Seq machine. Retrieved data was then used to verify the 5’-termini of predicted target mRNA.

Project description:The wild grass Brachypodium distachyon has emerged as a model system for temperate grasses and biofuel plants. However, the global analysis of miRNAs, molecules known to be key for eukaryotic gene regulation, has been limited in B. distachyon to studies examining a few samples or that rely on computational predictions. Similarly an in-depth global analysis of miRNA-mediated target cleavage using Parallel Analysis of RNA Ends (PARE) data is lacking in B. distachyon. B. distachyon small RNAs were cloned and deeply sequenced from 17 libraries that represent different tissues and stresses. Using a computational pipeline, we identified 116 miRNAs including not only conserved miRNAs that have not been reported in B. distachyon, but also non-conserved miRNAs that were not found in other plants. To investigate miRNA-mediated cleavage function, four PARE libraries were constructed from key tissues and sequenced to a total depth of approximately 70 million sequences. The roughly 5 million distinct genome-matched sequences that resulted represent an extensive dataset to analyze small RNA-guided cleavage events. Analysis of the PARE and miRNA data provided experimental evidence for miRNA-mediated cleavage of 264 sites in predicted miRNA targets. In addition, PARE analysis revealed that differentially expressed miRNAs in the same family guide specific target RNA cleavage in a correspondingly tissue-preferential manner. B. distachyon miRNAs and target RNAs were experimentally identified and analyzed. Knowledge gained from this study should provide insights into the roles of miRNAs and the regulation of their targets in B. distachyon and related plants.
