Project description:The present study is expected to reveal regulatory network of small RNAs under drought in Sorghum (Sorghum bicolor (L.) Moench). Sorghum genotype drought tolerant (DT) and drought susceptible (DS) were grown at 28-32 degrees C day/night temperature with 12/12 h light/dark period in the phytotron glass house. The fully opened uppermost leaves from control and drought stressed seedlings were sampled and stored at -80 degrees C, and used for generation of a small RNA library. Total RNA was isolated from the leaves using the TRIzol reagent (Invitrogen, USA). Small RNA sequencing libraries were prepared using Illumina Truseq small RNA Library preparation kit following manufacturer's protocol and these libraries were sequenced on GAIIx platform (Illumina Inc., USA). Small RNA reads contaminated with poor-quality and adaptor sequences were trimmed by using the UEA sRNA workbench 2.4- Plant version sequence file pre-processing (http://srna-tools.cmp.uea.ac.uk/). Then, all unique reads were submitted to the UEA sRNA toolkit-Plant version miRCat pipeline (http://srna-tools.cmp.uea.ac.uk/) to predict novel miRNAs from high-throughput small RNA sequencing data.

Project description:This study used with RNA-Seq to examine the tissue specific expression data within sorghum plants for improving the Sorghum bicolor gene annotation. We examined the RNA from tissues (spikelet, seed and stem) in Sorghum bicolor (BTx623).Total RNAs form each tissues were extracted using SDS/phenol method followed by LiCl purification

Project description:Small RNAs (21-24 nt) are pivotal regulators of gene expression that guide both transcriptional and post-transcriptional silencing mechanisms in diverse eukaryotes, including most if not all plants. MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are the two major types, both of which have a demonstrated and important role in plant development, stress responses and pathogen resistance. In this work, we used a deep sequencing approach (Sequencing-By-Synthesis, or SBS) to develop sequence resources of small RNAs from Sorghum bicolor tissues (including leaves, flowers and panicle). The high depth of the resulting datasets enabled us to examine in detail critical small RNA features as size distribution, tissue-specific regulation and sequence conservation between different organs in this species. We also developed database resources and a dedicated website (http://smallrna.udel.edu/) with computational tools for allowing other users to identify new miRNAs or siRNAs involved in specific regulatory pathways, verify the degree of conservation of these sequences in other plant species and map small RNAs on genes or larger regions of the genome under study.

Small RNA libraries were derived from leaves, flowers and panicle of Sorghum bicolor. Total RNA was isolated using the Plant RNA Purification Reagent (Invitrogen), and submitted to Illumina (Hayward, CA, http://www.illumina.com) for small RNA library construction using approaches described in (Lu et al., 2007) with minor modifications. The small RNA libraries were sequenced with the Sequencing-By-Synthesis (SBS) technology by Illumina. PERL scripts were designed to remove the adapter sequences and determine the abundance of each distinct small RNA. We thank Patricia Klein for providing the plant material as well as Kan Nobuta and Gayathri Mahalingam for assistance with the computational methods.

Project description:* The high sequence and structural similarities between BRI1 brassinosteroid receptors of Arabidopsis (AtBRI1) and sorghum (SbBRI1) prompted us to study the functionally conserved roles of BRI in both organisms. * Introducing sorghum SbBRI1 in Arabidopsis bri1 mutants restores defective growth and complements developmental phenotypes to WT levels. * Sorghum mutants for SbBRI1 receptors show defective BR sensitivity and results in impaired growth and development throughout the entire sorghum life cycle. Embryonic analysis of sorghum primary roots traced the root growth and development at the early stages, revealing the role of SbBRI1 in BR perception during cell division and BR sensing. RNA-seq of SbBRI1 mutants support the roles of SbBRI1 in cell wall biosynthesis and remodeling. * Together, these results uncover that sorghum SbBRI1 receptor protein play functionally conserved roles in plant growth and development.

Project description:Sorghum plants (Btx623 background) were grown in a glasshouse between March and May 2014. At panicle emergence, two biological replicates of flag leaf tissue and two biological replicates of emerging panicle tissue were harvested and used for RNA extraction. Btx623 is a non-shattering Sorghum accession, thus in the future we would like to add additional samples from accessions with varying degrees of seed shattering. This dataset will be useful for future comparisons of 1) shattering individuals at these stages and 2) additional flowering developmental time points in a variety of accessions (http://www.rnaseqforthenextgeneration.org/profiles/carrie-thurber.html#research)

Project description:We report transcriptome profiling of middle internode tissues from four development stages and three soil moisture readings representing progressive drought stress in sweet sorghum. Sequencing of 14 libraries (two biological replicates for each stage). Each replicate yielded an average of 86 million reads per sample for developmental stages and drought stressed samples yielded an average of 74 million reads per sample .
