Project description:RNA was isolated from 23 old barley plants (shoots and roots), line Rolap. PARE libraries were constructed for both barley organs, followed by sequencing of NGS libraries.

Project description:RNA was isolated from 23 old barley plants (shoots and roots), line Rolap. We used a modified method that allows for enrichment of small RNAs. Libraries were prepared using TruSeq Small RNA Library Preparation Kit (Illumina), followed by sequencing of NGS libraries.
Project description:Fourteen days plants growth under hydroponic +P condition (200 µM) were treated with +P(200µM) or –P (no phosphate) for another 7 days, shoot of plants from 3 biological repeats were sampled for Affymetrix microarray analysis. We used microarrays to detail the global programme of gene expression underlying +Pi and -Pi condition between WT and spx1spx2 double mutant.
Project description:The advent of high-throughput sequencing has led to an explosion of studies into the diversity, expression, processing, and lifespan of RNAs. Recently, three different high-throughput sequencing-based methods have been developed to specifically study RNAs that are in the process of being degraded. All three methods—genome-wide mapping of uncapped and cleaved transcripts (GMUCT), parallel analysis of RNA ends (PARE), and degradome sequencing—take advantage of the fact that Illumina sequencing libraries use T4 RNA ligase 1 to ligate an adapter to the 5’ end of RNAs that have a free 5’-monophosphate. This condition for T4 RNA ligase 1 substrates means that mature mRNAs are not substrates of the enzyme because they have a 5’-cap. As a result, these sequencing libraries are specifically made up of clones of decapped or degrading mRNAs and the 3’ fragment of cleaved miRNA and siRNA targets. In this paper, we present a massively streamlined protocol for GMUCT that takes 2-3 days and can be initiated with as little as 5 µg of starting total RNA and involves only one gel size-selection step. We show that the results are similar to libraries made using the previous GMUCT protocol and PARE.
