ABSTRACT: Single nucleotide polymorphism (SNP) markers for genetic diversity and population structure study in Ethiopian barley (Hordeum vulgare L.) germplasm
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: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: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:Purpose: The powdery mildew fungus, Blumeria graminis, is an obligate biotrophic pathogen of cereals and has significant impact on food security (Dean et al., 2012. Molecular Plant Pathology 13 (4): 414-430. DOI: 10.1111/j.1364-3703.2011.00783.x). Blumeria graminis f. sp. hordei (Bgh) is the causal agent of powdery mildew on barley (Hordeum vulgare L.). We sought to discover novel transcripts expressed following barley infection with blumeria.

Project description:High temperature stress, like any abiotic stress, impairs the physiology and development of plants, including the stages of seed setting and ripening. In this study we used the 22K Barley1 GeneChip microarray to investigate the response of developing barley (Hordeum vulgare) caryopses at 12 days post anthesis to 0.5h, 3h and 6h of heat stress exposure.

Molecular Plant Pathology 13 (4): 414-430. DOI: 10.1111/j.1364-3703.2011.00783.x). Blumeria graminis f. sp. hordei (Bgh) is the causal agent of powdery mildew on barley (Hordeum vulgare L.). We sought to identify small RNAs (sRNAs) from both barley and Bgh that regulate gene expression both within species and cross-kingdom.
Project description:Gene expression was investigated in response to nitrogen fertilizer in developing grains of field grown barley (Hordeum vulgare L. cv. Barke) at four different time points: 10, 15, 18 and 25 days after pollination (DAP).
