Project description:To determine the extent to which the major small RNA pathways functions across the Arabidopsis thaliana genome, small RNA populations from several tissues of wild-type (wt) and mutant plants were amplified by RT-PCR and sequenced using high-throughput 454 sequencing technology. Keywords: small RNAs, high-throughput sequencing Amplicons were prepared by 5' and 3' adaptor ligation and RT-PCR using small RNA fractions from inflorescence tissue (containing stage 1-12 flowers) of wt Col-0 plants, mutants with defects in each DCL gene (dcl1-7, dcl2-1, dcl3-1, dcl4-2), and mutants with defects in each RDR gene for which a function has been established (rdr1-1, rdr2-1, rdr6-15). Amplicons from whole seedlings (3 day post-germinations) were prepared from Col-0 and rdr6-15 plants. Small RNA preparations from leaf samples of Col-O that were either uninoculated or inoculated by Pseudomonas syringae pv tomato (DC3000hrcC) for 1 hr and 3 hr were also sequenced.
Project description:Comparison of the endogenous small RNA content of Arabidopsis flower bud tissue: wild type vs. mutants in polIV pathways Keywords: High throughput 454 small RNA sequencing. Size fractionated small RNA from total RNA extracts was ligated to adapters, purified again and reverse transcribed. After PCR amplification the sample was subjected to 454 high throughput pyrosequencing. Please see www.454.com for details of the sequencing technology.
Project description:Small RNA sequences from Arabidopsis thaliana Col-0 inflorescence tissues of three biological replicates. The data were analyzed to identify non-templated nucleotides in Arabidopsis small RNAs.
Project description:High-throughput sequencing of Drosophila melanogaster small RNAs. total RNA, ~18-26nt RNAs isolated using PAGE, ligation to adapters requires 5' monophosphate and 3' OH Keywords: high-throughput 454 sequencing

Project description:Mustard (Brassica juncea) was tested for Turnip mosaic virus infection. Small RNA of the plant was extracted and converted to DNA according to Ho, T., et al. (2006) Journal of Virological Methods 136:217-223, with primers modified to contain 454 adapter nucleotide sequences. The DNA then passed quality control through Bioanalyzer and Nanodrop before sequenced by 454 Life Sciences. Keywords: siRNA One sample analyzed by 454 high-throughput sequencing technology
Project description:Cocksfoot grass (Dactylis glomerata) collected from Wytham, Oxford, UK, was tested for Cocksfoot streak virus infection. Small RNA of the grass was extracted and converted to DNA according to Ho, T., et al. (2008) Biochem Biophys Res Commun. 368:433-7, with primers modified to contain 454 adapter nucleotide sequences. The DNA then passed quality control through Bioanalyzer and Nanodrop before sequenced by 454 Life Sciences. Keywords: siRNA One sample analyzed by 454 high-throughput sequencing technology
Project description:This data series contains the sequences and read counts of Piwi-interacting RNAs and other small RNAs from mouse and rat testes extracts. In a search for different classes of small RNAs that might be involved in transcriptional gene silencing, we encountered a novel class of small RNAs within mammalian testes. This study reports the identification of small RNAs and their relative abundance levels to each other based on the deep coverage of the cDNA library. Keywords: High-throughput pyrosequencing by the 454 Life Sciences Genome Sequencer 20™ System
