SNP Discovery in Nine Lines of Cultivated Barley

ABSTRACT: Barley (Hordeum vulgare L.) is amongst the oldest domesticated crop plants and remains one of the world's most important crop species. It is diploid with a haploid genome of 5.1 gigabases (Gb), twice the size of those of human and maize, and closely related to the most widely grown crop, hexaploid wheat. To meet global demand for food, feed and fibre, it is commonly agreed that reference genome sequences of our crop plants are urgently required to enable genome-assisted crop improvement. As part of the The International Barley Genome Sequencing Consortium (IBSC) we present here raw data obtained from Illumina (GAII) sequencing of RNA samples from nine different barley cultivars for the purpose of Single Nucleotide Polymorphism (SNP) discovery.

Barley (Hordeum vulgare L.) is among the world's earliest domesticated and most important crop plants. It is diploid with a large haploid genome of 5.1 gigabases (Gb). Here we present an integrated and ordered physical, genetic and functional sequence resource that describes the barley gene-space in a structured whole-genome context. We developed a physical map of 4.98 Gb, with more than 3.90 Gb anchored to a high-resolution genetic map. Projecting a deep whole-genome shotgun assembly, complemen ...[more]

Transcription profiling of mouse fibroblasts ectopically expressing runx ti investigate the transcriptional program for control of cell adhesion and survival

Project description:The Runx genes are important in development and cancer, where they can act either as oncogenes or tumour supressors. We compared the effects of ectopic Runx expression in established fibroblasts, where all three genes produce an indistinguishable phenotype entailing epithelioid morphology and increased cell survival under stress conditions. Gene array analysis revealed a strongly overlapping transcriptional signature, with no examples of opposing regulation of the same target gene. A common set of 50 highly regulated genes was identified after further filtering on regulation by inducible RUNX1-ER. This set revealed a strong bias toward genes with annotated roles in cancer and development, and a preponderance of targets encoding extracellular or surface proteins reflecting the marked effects of Runx on cell adhesion. Experiment Overall Design: 6 samples (expression of different Runx family members); 5 in duplicate, 1 single. 2 control samples (empty vector) in duplicate. Cultures of Runx expressing cells were grown to confluence, treated with ethanol +/- 4OHT tamoxifen for 24 hours and harvested for RNA extraction and hybridization on Affymetrix microarrays

Transcription profiling of barley lemma, palea, awn and developing seed

Project description:The lemma, the palea and the awn of a barley spike are photosynthetic organs and supply the developing seed with carbohydrates. In addition, the lemma and the palea cover the seed and protect it from pathogens and insects. In this study, we compared gene expression among the lemma, the palea, the awn and the developing seed of barley at the grain-filling stage (Zadok scale 83) using the Barley1 Genome Array in order to identify genes that determine the primary function of these organs. Experiment Overall Design: Lemma, palea, awn and seed were collected at grain-filling stage (Zadok scale 83) to compare differences in gene expression. For each organ three biological replications were collected on three different dates. On each of the three dates, one replication of each organ was collected from plants grown in separate pots using a randomized complete block design (RCBD). In ths design, organ type was the treatment effect and date of sample collection (replication) was the block. To get enough tissue for RNA extraction, each replication for each organ was collected from four plants in the same pot. RNA from each replicate sample was hybridized to individual Barley1 GeneChips. Thus, for four organs with three replications (blocks), a total of 12 Barley1 GeneChips were used.

Revealing the constituents of Egypt’s oldest beer using infrared and mass spectrometry

Project description:Previous studies have shown that the Ancient Egyptians used malted wheat and barley as the main ingredients in beer brewing, but the chemical determination of the exact recipe is still lacking. To investigate the constituents of ancient beer, we conducted a detailed IR and GC-MS based metabolite analyses targeting volatile and non-volatile metabolites on the residues recovered from the interior of vats in what is currently the world's oldest (c. 3600 BCE) installation for large-scale beer production located at the major pre-pharaonic political center at Hierakonpolis, Egypt. In addition to distinguishing the chemical signatures of various flavoring agents, such as dates, a significant result of our analysis is the finding, for the first time, of phosphoric acid in high level probably used as a preservative much like in modern beverages. This suggests that the early brewers had acquired the knowledge needed to efficiently produce and preserve large quantities of beer. This study provides the most detailed chemical profile of an ancient beer using modern spectrometric techniques and providing evidence for the likely starting materials used in beer brewing.

RNA-seq of enriched barley stomatal complexes versus total leaves

Project description:We intend to identify transporters and their regulators involved in barley stomatal movement as well as components of the ABA signaling pathway. We isolated epidermal peels where only stomatal guard cells and their subsidiary cells survived, while other epidermal cell were mechanically disrupted and sequenced the resulting RNAs. Thus we analyzed transcripts differentially expressed between the barley stomatal complex and total leaves. These data served as the first overview of genes expressed in the stomatal complex and for cloning of relevant transporters.

Barley guard cell and subsidiary cell specific transcripts

Project description:We prepared RNA from total leaves and epidermal peels, containing living guard cells (GC) and subsidiary cells (SC) only. In the third sample we blended epidermal peels to mechanically destroy the SC, leading to a pure guard cells fraction. By RNAseq and substraction of GC from SC transcripts, we were able to reliably assign transcripts to the barley SCs and GCs.

Barley Systemic Immunity: Dataset Local and Systemic

Project description:Leaf-to-leaf, systemic immune signaling known as systemic acquired resistance (SAR) is poorly understood in monocotyledonous plants. Here, we characterize systemic immunity in barley (Hordeum vulgare) triggered after primary leaf infection with either Pseudomonas syringae pathovar japonica (Psj) or Xanthomonas translucens pathovar cerealis (Xtc). Both pathogens induced resistance in systemic, uninfected leaves against a subsequent challenge infection with Xtc. In contrast to SAR in Arabidopsis thaliana, systemic immunity in barley was not associated with NONEXPRESSOR OF PATHOGENESIS-RELATED GENES1 or the local or systemic accumulation of salicylic acid (SA). Instead, we documented a moderate local but not systemic induction of abscisic acid (ABA) after infection of leaves with Psj. In contrast to SA or its functional analog benzothiadiazole, local applications of the jasmonic acid methyl ester or ABA triggered systemic immunity to Xtc. RNA-seq analysis of local and systemic transcript accumulation revealed unique gene expression changes in response to both Psj and Xtc and a clear separation of local from systemic responses. The systemic response appeared relatively modest and quantitative RT-PCR associated systemic immunity with the local and systemic induction of two WRKY and two ETHYLENE RESPONSIVE FACTOR-like transcription factors. Systemic immunity against Xtc was further associated with transcriptional changes after a secondary/systemic Xtc challenge infection; these changes were dependent on the primary treatment. Taken together, bacteria-induced systemic immunity in barley may be mediated in part by WRKY and ERF-like transcription factors possibly facilitating transcriptional reprogramming to potentiate immunity.

Transcription profiling of barley lemma, palea, awn and seed from drought-stressed plants

Project description:The photosynthetic organs of the barley spike (lemma, palea and awn) are resistant to drought. This is a beneficial trait because they can sustain grain-filling when drought occurs at the reproductive stage. There is little information about gene expression in the spike organs under drought conditions. In this study, we compared gene expression in drought-stressed lemma, palea, awn and seed at the grain-filling stage using the Barley1 Genome Array in order to identify drought-regulated organ-specific genes. Experiment Overall Design: Barley plants were drough-stressed for 4 days at the grain-filling stage by withholding water. Lemma, palea, awn and seed were collected to determine gene expression during drought in each organ. For each organ three biological replications were collected on three different dates. On each of the three dates, one replication of each organ was collected from plants grown in separate pots using a randomized complete block design (RCBD). In ths design, organ type and drought treatment were treatment effects and date of sample collection (replication) was the block. To get enough tissue for RNA extraction, each replication for each organ was collected from four plants in the same pot. RNA from each replicate sample was hybridized to individual Barley1 GeneChips. Thus, for four organs with three replications (blocks) and two treatment levels, a total of 24 Barley1 GeneChips were used.
