Project description:This experiment contains the subset of data corresponding to sorghum RNA-Seq data from experiment E-GEOD-50464 (http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-50464/), which goal is to examine the transcriptome of various Sorghum bicolor (BTx623) tissues: flowers, vegetative and floral meristems, embryos, roots and shoots. Thus, we expanded the existing transcriptome atlas for sorghum by conducting RNA-Seq analysis on meristematic tissues, florets, and embryos, and these data sets have been used to improve on the existing community structural annotations.

Project description:This study utilized next generation sequencing technology (RNA-Seq) to examine the transcriptome of sorghum plants challenged with osmotic stress and exogenous abscisic acid (ABA) to elucidate those genes and gene networks that contribute to sorghum's tolerance to water-limiting environments with a long-term aim of developing strategies to improve plant productivity under drought. We examined the mRNA of 9 day old Sorghum bicolor (BTx623) from 2 tissue types (roots and shoots) for 2 treatments (20 uM ABA and 20% PEG) with corresponding controls (0.2M NaOH and H2O) for 27 hrs prior to harvesting, each done in triplicate biological replicates - resulting in 24 unique runs

Project description:To characterize the expression of 58219 genes annotated from garlic genome, the transcriptomes of seven tissues (including garlic sprouts, shoots, bulbs, flowers, roots, pesudostems, and leaves) were sequenced, and finally identified 45,750 genes expressed in various tissues investigated. In addition, the bulbs-transcriptomes in the eight stages of bulbs-development were sequenced, resulting in 6,234 genes isentified to show dynamic expression changes in the bulbs-developmental process.

Project description:We developed a commercially available whole-transcriptome sorghum microarray (Sorgh-WTa520972F) and generated this dataset to identify tissue and genotype-specific expression patterns for all identified Sorghum bicolor exons and UTRs. The genechip contains 1,026,373 probes covering 149,182 exons (27,577 genes) across the Sorghum bicolor nuclear, chloroplast and mitochondrial genomes. Specific probesets were also included for putative non-coding RNAs that may play a role in gene regulation (e.g., microRNAs), and confirmed functional small RNAs in related species (corn and sugarcane) were also included in our array design. 78 samples were analyzed from four different tissue types (shoot, seedling, leaves and stem), two dissected stem tissues (pith and rind) and six diverse genotypes (PI455230, Atlas, PI152611, AR2400, R159, and Fremont)

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:Plants initially undergo a period of vegetative development, in which it produces leaves from shoot apical meristem (SAM) and roots from the root apical meristem. Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. In this study, we have analyzed the spatial and temporal gene expression in various tissues/organs and developmental stages of rice using microarray technology to identify the genes differentially expressed during various stages of reproductive development.

Project description:This dataset contains raw spectral data captured from sorghum roots collected from four Sorghum bicolor L. Moench genotypes grown in an arid field setting in Maricopa, Arizona in water-replete and water-limited conditions. We used these data to examine the root metabolome of field-grown sorghum in Arizona, USA, and related metabolomic data to microbial responses to stress.
