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:There is growing evidence for the prevalence of DNA copy number variation (CNV) and its role in phenotypic variation in recent years. Comparative genomic hybridization (CGH) was used to explore the extent of this type of structural variation in the barley genome. In a panel of 14 genotypes including domesticated cultivars and wild barleys, we found that 14.9% of all the sequences on the array are affected by CNV. Higher levels of CNV diversity are present in the wild accessions relative to cultivated barley. A substantial portion (37%) of the CNV events are present in both wild and domesticated barley. CNVs are enriched in telomeric regions for all chromosomes except 4H, which is also the barley chromosome with the lowest proportion of CNVs. CNV affected 9.5% of the coding sequences represented on the array. The genes affected by CNV are enriched for sequences annotated as disease-resistance proteins and protein kinases, suggesting the potential for CNV to influence variation for responses to biotic and abiotic stress. The analysis of CNV breakpoints indicated that DNA repair mechanisms of double-strand breaks (DSBs) via single-stranded annealing (SSA) and synthesis-dependent strand annealing (SDSA) play an important role in the origin of many structural changes in barley. Here we present the first catalog of CNVs in a diploid Triticeae species, which opens the door for future genome diversity research in a tribe that comprises the economically important cereal species wheat, barley and rye. Our findings constitute a valuable resource for the identification of CNV affecting genes of agronomic importance.

Project description:We provide raw gene sequences of 174 flowering time regulatory genes and gene othologs across a large barley population (895 barley lines) selected from a collection of landrace, cultivated barley, and research varieties of diverse origin. This set represents the whole variety of cultivated barley lifeforms, namely two- and six-row genotypes with winter, spring, and facultative growth habits. We applied a target capture method based on in-solution hybridization using the myBaits® technology (Arbor Biosciences, Ann Arbour, MI, USA) which is based on in-solution biotinylated RNA probes. Baits were designed for flowering time regulatory genes and gene othologs, and used for production of 80mer capture oligonucleotides for hybridization. Genomic DNA was extracted from leaves of a single two-week old barley plant per variety using the cetyl-trimethyl-ammonium bromide (CTAB) method. Physical shearing of genomic DNA was performed with an average size of 275 bp. Library preparation was conducted with KAPA Hyper Prep Kit (KAPA Biosystems, Wilmington, MA). Hybridization of customised RNA baits with capture pools was performed at 65°C for 24 hours. Each pooled sequence capture library was sequenced on an Illumina HiSeq3000 instrument using three lanes to generate paired-end reads per sample. Genome sequencing was conducted at AgriBio, (Centre for AgriBioscience, Bundoora, VIC, Australia).

Project description:Barley contains a much higher content of bioactive substances than wheat. In order to investigate the effect of genome interaction between barley and wheat on phytosterol content, we used a series of barley chromosome addition lines of common wheat. The wheat 38k-microarray was utilized for screening of genes with expression levels specifically increased by an additive effect or synergistic action between wheat and barley chromosomes. We determined the overall expression pattern of genes related to phytosterol biosynthesis in wheat and in each addition line. Together with determining the phytosterol levels of wheat, barley and each addition line, we assess the critical genes in the phytosterol pathway that can be expressed to promote phytosterol levels.

Project description:Chevallier is a heritage english landrace of barley first planted in 1820 while Tipple is modern cultivar of barley released in 2004. Pseudomonas strains were isolated from the rhizospheres of the two varieties and 22 and 20 of the most phylogenetically distinct ones were sequenced to find out the difference in genotypes preferentially selected in the rhizospheres of the two cultivars.
