Project description:The ligation step in RNA sequencing library generation is a known source of bias. We present the first comparison of the standard duplex adaptor protocol supplied by Life Technologies for use on the Ion Torrent PGM with an alternate single adaptor approach involving CircLigase (CircLig). We also investigate whether using the thermostable ligase Methanobacterium thermoautotrophicum RNA ligase K97A (Mth K97A) for the initial ligation step in the CircLigase protocol reduces bias. A pool of small RNA fragments of known composition was converted into a sequencing library using one of three protocols and sequenced on an Ion Torrent PGM. The single adaptor CircLigase-based approach significantly reduces, but does not eliminate, bias in Ion Torrent data. Using Mth K97A as part of the CircLig method does not further reduce bias.

Project description:Exosomes/microvesicles (hereafter referred to as extracellular vesicles) were isolated from the ULF of day 14 cyclic and pregnant ewes using ExoQuick-TC. Extracellular vesicle RNA was pooled (n=4 per status) and analyzed for small RNAs by sequencing on the Ion Torrent PGM platform and analysis with CLC Genomics Workbench small RNA workflow based on the miRBase (Release 19) Bos taurus database.

Project description:Purpose: to reveal the small RNA profile of postnatal retina in Wistar WU albino rat by Ion-Torrent PGM sequencing technology. Methods : Wistar WU rats ranging in age from P1 to P21 were anesthetized by inhalation using Forane prior to sacrifice at the same hour to avoid circadian variation. Total RNA was extracted from the retinal tissues of various developmental stages using NucleoSpin miRNA kit (Macherey–Nagel, Düren, Germany) following manufacturer's instructions. The miRNA concentration was assessed using Qubit microRNA Assay Kit (ThermoFisher Scientific, MA, USA). The RNA integrity number (RIN), an algorithm for judging the integrity of RNA samples, were evaluated using Agilent 2100 Bioanalyzer (Agilent Technologies, USA) following the manufacturing instruction of the RNA 6000 Nano kit and RIN>7 was considered acceptable. MicroRNAs was also determined using the Agilent Small RNA Kit to have deeper view in the 10 to 40-nucleotide size range. Small RNA library construction from pooled retinal samples (N=3, in each age-group) were carried out according to the Ion Total RNA-Seq Kit v2 protocol (Revision E) with slight modification. Enzymatic reaction was performed in half reaction volume, while cleaning procedures were executed with the accurate final volume according to the protocol. The Ion 316 or 318 ™ Chip v2 was used for sequencing on the Ion Torrent PGM™ instrument according to the protocol of Ion PGM™ Hi-Q View Sequencing Kit. To assess reliability of miRNA workflow solution in 316 v2 chip, two independent P7 samples were assayed (biological replicates) and P21 sample were sequenced as technical replicates in every sequencing procedure. Some samples were also sequenced in 318 v2 chip (P3, P5, P10, P15 and P21) as biological replicate. Ion Torrent Suite Platform was used to trim the raw sequence data and remove any residual sequencing adapter fragments that remained on the 5′ or 3′ ends. Reads were mapped to the non-coding RNAs from ENSEMBL [Rnor_6.0 (GCA_000001895.4)] using TMAP algorithm. These aligned BAM (Binary Alignment Map) files were further processed in Galaxy Web-based platform (Afgan, 2018) via Cufflinks, Cuffmerge and Cuffdiff (Version 2.2.1.3) application (Trapnell, 2010). Further analysis and visualising of the datasets was carried out in R Studio Software environment. qRT–PCR validation was performed using TaqMan assays.

Project description:Purpose: Molecular analysis of chickpea-Foc interaction; Methods: Four LongSAGE libraries of wilt-resistant and wilt-susceptible chickpea cultivars prepared after Foc inoculation and sequenced using Ion Torrent PGM. Results: Transcriptome analyses revealed expression of several plant defense and pathogen virulence genes with their peculier expression patterns in wilt-resistant and wilt-susceptible chickpea cultivars. Conclusion: The study identified several candidate Foc resistant genes, which can be used for crop improvement after their functional validation.

Project description:Purpose: Study transcriptome differences between biofilm, planktonic and stationary cultures. Methods: Total mRNA from in vitro cultures was extracted and sequenced using Ion Torrent PGM sequencer. Results: Characteristic transcriptomic profile was observed for biofilm, planktonic and stationary cultures. Biofilm and planktonic were similar biological states. Conclusions: Results suggest that H. parasuis F9 has more active metabolism during biofilm or planktonic growth when compared to stationary culture. Some identified membrane-related genes could play an important role in biofilm life.

Project description:We report a complex operon architecture for R. capsulatus: operons with multiple TSSs and TTSs, genomic regions of high transcriptional activity and novel transcripts. In addition, we present a new 5' and 3' targeted sequencing method for the Ion Torrent PGM. TEX+ and TEX- indicates if the dRNA-seq library was treated with Terminator 5'-Phosphate-Dependent Exonuclease or not. Treatment with TEX degrades every RNA that does not have a 5'-PPP.
