Project description: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.

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.

Project description:In this study, we used transcriptomic and hormonomic approaches to examine drought-induced changes in barley roots and leaves and its rhizosphere. By studying hormonal responses, alternative splicing events in barley, and changes in the rhizosphere microbiome, we aimed to provide a comprehensive view of barley drought-adaptive mechanisms and potential plant-microbe interactions under drought stress. This approach improved our understanding of barley adaptive strategies and highlighted the importance of considering plant-microbe interactions in the context of climate change.

Project description:Aphids are phloem-feeding insects that cause yield loss on a wide range of crops, including cereals such as barley. While most aphid species are limited to one or few host species, some are able to reproduce on many plants belonging to different families. Interestingly, aphid probing-behaviour can be observed on both host and non-host species indicating that interactions take place at the molecular level that may impact host range. Here, we aimed to gain insight into the interaction of barley with aphid species differing in their ability to infest this crop by analysing transcriptional responses. First, we determined colonization efficiency, settlement, and probing behaviour for the aphid species Rhopalosiphum padi, Myzus persicae and Myzus cerasi, which defined host, poor-host and non-host interactions, respectively. Analyses of barley transcriptional responses revealed gene sets differentially regulated upon the different barley-aphid interactions and showed that the poor-host interaction with M. persicae resulted in the strongest deregulation of genes. Interestingly, we identified several thionin genes strongly up-regulated upon interaction with M. persicae, and to a lesser extend upon R. padi interaction. Ectopic expression of two of these genes in Nicotiana benthamiana reduced host susceptibility to M. persicae, indicating thionins contribute to defences against aphids.

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.

Project description:The wheat gene Lr34 (Yr18/Pm38/Sr57/Ltn1) encodes a putative ABCG-type of transporter and is a unique source of disease resistance providing durable and partial resistance against multiple fungal pathogens. Lr34 has been found to be functional as a transgene in barley. We used microarrays to decipher the changes in global gene expression governed by Lr34 expression in barley. Leaves from two independent lines of transgenic barley plants were selected at seedling (two weeks old plants) and mature (six weeks old plants) stages of development for RNA extraction and hybridization on Affymetrix microarrays. We used three biological replicates for expression profiles. Wild type plants served as controls.

Project description:Many plants dramatically elongate their vegetative stems following flowering, yet it is unclear how this response is linked to the reproductive phase. We show that microRNA (miRNA) control of a deeply conserved phase change transcription factor, APETALA (AP2), is required for rapid and complete elongation of stem internodes in barley, especially of the final 'peduncle' internode directly underneath the inflorescence. Disrupted miR172-targeting of AP2 causes leads to short peduncles in the Zeo barley mutant due to reduced cell number and late stage cell expansion, which was associated with lower mitotic activity, delayed growth dynamics and premature lignification. In agreement, multiple, stage and tissue specific comparative transcriptomics revealed decreased expression of proliferation-associated genes, and ectopic expression of maturation-related genes in Zeo1.b. In addition, Zeo1.b peduncles showed persistent, elevated expression of genes associated with jasmonate (JA) and stress responses. Reproductive development including stem elongation in Zeo1.b was hypersensitive to inhibition by methyl JA (MeJA) but less responsive to promotion via gibberellin (GA). Based on these data, we propose that miR172- restriction of AP2 during flowering may release JA-associated vegetative growth restraint in order to facilitate GA-promoted stem growth in the reproductive phase.

Project description:Barley is an important cereal crop all over the world. Detailed molecular characterization of barley provides the basis for development of improved cultivars, stress and drought-resistant plants. We here present an LC-MS/MS-based proteomics study of barley leaf aimed at optimization of methods to achieve efficient and unbiased trypsin digestion of proteins prior to LC-MS/MS based sequencing and quantification of peptides. We evaluated two spin filter-aided sample preparation protocols using either sodium dodecyl-sulphate (SDS) or sodium deoxycholate (SDC), and three in-solution digestion (ISD) protocols using SDC or trichloroacetic acid/acetone precipitation. The proteomics workflow identified up to 1800 barley proteins based on sequencing of up to 7700 peptides per sample. The two spin filter-based protocols provided a 17-38% higher efficiency than the ISD protocols, including more proteins of low abundance. Among the ISD protocols, a simple one-step reduction and S-alkylation method (OP-ISD) was the most efficient for barley leaf sample preparation; it identified and quantified 1500 proteins and displayed higher peptide-to-protein inference ratio and higher average amino acid sequence coverage of proteins. The two spin filter-aided sample preparation protocols are compatible with TMT labeling for quantitative proteomics studies. They exhibited complementary performance as about 30% of the proteins were identified by either one or the other protocol, but also demonstrated a positive bias for membrane proteins when using SDC as detergent. We provide detailed protocols for efficient barley protein sample preparation for LC-MS/MS-based proteomics studies. Spin filter-based protocols are the most efficient for the preparation of barley leaf samples for MS-based proteomics, however, a simple protocol provides comparable results although with different peptide digestion profile.
