Project description:Gene expression in plastids of higher plants is dependent on two different transcription machineries, a plastid-encoded bacterial-type RNA polymerase (PEP) and a nuclear-encoded phage-type RNA polymerase (NEP), which recognize distinct types of promoters. The division of labor between PEP and NEP during plastid development and in mature chloroplasts is unclear due to a lack of comprehensive information on promoter usage. Here we present a thorough investigation into the distribution of PEP and NEP promoters within the plastid genome of barley (Hordeum vulgare L). Using a novel differential RNA sequencing approach, which discriminates between primary and processed transcripts, we obtained a genome-wide map of transcription start sites in plastids of mature first leaves. PEP-lacking plastids of the albostrians mutant allowed for the unambiguous identifications of NEP promoters. We observed that the chloroplast genome contains many more promoters than genes. According to our data, most genes (including genes coding for photosynthesis proteins) have both PEP and NEP promoters. We also detected numerous transcription start sites within operons indicating transcriptional uncoupling of genes in polycistronic gene clusters. Moreover, we mapped many transcription start sites in intergenic regions, as well as opposite to annotated genes demonstrating the existence of numerous non-coding RNA candidates.

Project description:This experiment showed the microarray expression of a barley recessive mutant (G132) and its wild type (Hordeum vulgare cv. Graphic) under high CO2 concentration. The homozygous mutation has a strong pleiotropic nature affecting many aspects of plant. In order to identify target genes of this mutation, changes in gene expression of mutant and its responses to elevated CO2 were compared to wild type.

Project description:To provide comprehensive spatiotemporal information about biological processes in developing grains of cultivated barley (Hordeum vulgare subsp. vulgare), we performed a transcriptomic study of the embryo, endosperm, and seed maternal tissues collected from 4 to 32 days after pollination.

Project description:To provide comprehensive spatiotemporal information about biological processes in developing grains of cultivated barley (Hordeum vulgare subsp. vulgare), we performed a chromatin immunoprecipitation of H3K27me3 followed by high-throughput sequencing (ChIP-seq) in barley endosperm at 16 days after pollination.

Project description:The molecular regulation of root initiation in monocots is still poorly understood. We report the development of the auxin-based crown-root inducible system (CRIS) in barley (Hordeum vulgare L.). Using this system coupled to RNAseq, we investigated the molecular events occurring during the early steps of crown-root (CR) initiation. The sequencing on the Illumina NovaSeq6000 platform yielded over 123 Gb data, representing more than 408 million reads. Using the last released barley annotation (Morex v2 Gene Models, 2019), we found that 427 genes were downregulated by auxin whereas 764 genes were upregulated. This study provides the first analysis of early event of crown-root initiation in cereals. It will serve as comparison with known genes in rice, maize and other cereals, and could be used in metagenomics studies.

Project description:Hordeum vulgare is one of the first domesticated grains in the world and it has been reported that variations in the light environment have a substantial effect on barley plant development and biological processes. High-throughput RNA-Seq study was performed to investigate the complex transcriptome network required for photomorphogenesis in barley. Seedlings were grown in dark and light conditions and three biological replicates were sampled from each condition. Six libraries from poly-A rich mRNA fraction were subjected to 51bp single-end RNA-seq sequencing.
