Project description:Transcriptional changes were monitored in the barley cultivar Golden Promise 24 hours post inoculation (hpi) with the bacteria Pseudomonas syringae pv. tomato DC3000 avrRpm1 (PstavrRpm1) using the Affymetrix Barley genome array GeneChip®. Seedlings of Golden Promise were grown to growth stage 12-13 (Zadoks et al., 1974) before inoculating with either PstavrRpm1 or water (for the mock inoculation control) by infiltration. Plants were grown under a 18 °C / 16 h light period; 12 °C / 8 h dark period, with artificial lighting (100 µmol m-2 s-1) and a relative humidity of 75 – 85 %. Leaf samples from three seedlings were collected 24 hpi for RNA extraction and transcriptomics analysis from the area infiltrated (local) and from the area next to the infiltrated region (adjacent) from three biological replicates. Leaf tissue was ground under liquid nitrogen and total RNA extracted using the RNeasy miniprep kit (Qiagen), following the manufacturer’s instructions. RNA was DNase treated using Turbo DNase (Ambion) according to the manufacturer instructions. RNA integrity was confirmed using the Agilent 2100 Bioanalyzer (Agilent). The two cycle-target labeling method was used following the Affymetrix protocol. Affymetrix GeneChip processing, including RNA quality control, microarray hybridisation and data acquisition was performed through contract research services by Cogenics (North Carolina, U.S.A.). A total of twelve hybridisations were performed. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Ellen Colebrook.

Project description:We hypothesized that the genome segments of cultivated barley should show certain similarity with its ancestral wild barley. Instead of whole genome sequences, we employed RNA-Seq to investigated the genomic origin of modern cultivated barley using some representative wild barley genotypes from the Near East and Tibet, and representative world-wide selections of cultivated barley.

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.
