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: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. dRNA-seq analysis of total RNA from green and white plastids of the barley mutant line albostrians

Project description:The barley brittle stem mutants, fs2, designated X054 and M245, have reduced levels of cellulose compared with their isogenic parents Ohichi and Shiroseto. A custom-designed microarray, based on Agilent technology and including genes involved in cell wall metabolism, was used to compare transcript levels in the mutant and parental lines. For both mutants, the microarray revealed a marked decrease in mRNA for the HvCesA4 cellulose synthase gene in specific zones of stem internodes, and this was confirmed by quantitative PCR.
