Project description:Seed germination triggers a transition of growth and metabolic activities from quiescent to active statuses. Germinating seeds is a good system to study many biological and biochemical processes including hormone metabolic activities and cell wall biosynthesis. Next generation sequence technology is used to study these processes. We have examined gene transcription activities and alternative splicing events in germinating embryos We dissected barley embryos from four barley varieties at 2 time points 24 h and 48 h

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:NILs containing five parental lines, three wild barley genotypes ssp. spontaneum: HID 4 (A), Iraq; HID 64 (B), Turkey; and HID 369 (C), Israel, one ssp. agriocrithon: HID 382(D)) and cv. Morex (ssp. vulgare, USA). Purpose: Variant calling to identifie markers associated with a awn length QTL on the distal part of chromosome 7HL
Project description:In the present study, we investigated the transcriptome features during hulless barley grain development. Using Illumina paired-end RNA-Sequencing, we generated two data sets of the developing grain transcriptomes from two hulless barley landraces.
Project description:In the lateral root repression system described by Babé et al. (2012), the first asymetric divisions of pericycle cells preceding lateral root formation are repressed during water deficit treatments. During an 8-hr long treatment, an 8-mm long root segment is formed where LR formation has been repressed. The experiment was designed to monitor changes in gene expression during early events of LR formation in barley using this LR repression system.
Project description:Waterlogging is a major abiotic stress causing oxygen depletion and carbon dioxide accumulation in the rhizosphere. Barley is more susceptible to waterlogging stress than other cereals. To gain a better understanding of the effect of waterlogging stress in barley, we carried out a genome-wide gene expression analysis in roots of Yerong and Deder2 barley genotypes under waterlogging and control (well-watered) conditions by RNA-Sequencing, using Illumina HiSeq™ 4000 platform.
Project description:Effect of high grain protein locus on barley grain protein accumulation. Gene expression levels were analysed in Karl, a low grain protein variety with its near-isogenic line 10_11(has high grain protein locus, chromosome 6)using Barley1 22k affymetrix chip. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Aravind Jukanti.
