Array-based genotyping and expression analysis of barley cv. Maythorpe and Golden Promise.

Project description:BACKGROUND: Golden Promise is a salt-tolerant spring barley closely related to Maythorpe. Salt tolerance in Golden Promise has been attributed to a single mutation at the Ari-e locus (on 5H) resulting from irradiation of Maythorpe. Golden Promise accumulates lower shoot Na+ compared to Maythorpe when growing under saline conditions. This study focused on elucidating the genetic basis and mechanisms involved in this difference. RESULTS: The level of polymorphism between the two genotypes was explored using the Barley1 GeneChip for single feature polymorphisms (SFPs) and an oligonucleotide pool assay for single nucleotide polymorphisms (SNPs). Polymorphism analyses revealed three haplotype blocks spanning 6.4 cM on chromosome 1H, 23.7 cM on chromosome 4H and 3.0 cM on 5H. The Barley1 GeneChip was used to examine transcript abundance in different tissues and stages during development. Several genes within the polymorphic haplotype blocks were differentially regulated. Additionally, a more global difference in the jasmonic acid pathway regulation was detected between the two genotypes. CONCLUSION: The results confirm that Golden Promise and Maythorpe are genetically very closely related but establish that they are not isogenic, as previously reported, due to three polymorphic haplotype blocks. Transcriptome analysis indicates that the response of the two genotypes to salinity stress is quite different. Additionally, the response to salinity stress in the roots and shoot tissue is strikingly different.

Transcriptomic changes in the crown (stem base) of barley (Hordeum vulgare L. cv. Golden Promise) during crown-root initiation and development

Project description:Purpose: The goal of this study was to investigate the mechanisms involved in the initiation and development of crown-roots (CRs) in barley and to estimate the role of cytokinins (CKs) in this process. Method: stranded libraries were obtained from RNA extracted from the stem base of 1 day-after-germination (DAG) and 10DAG-seedlings of wild-type (WT) and AtCKX-overexpressing barley lines (OE-CKX). OE-CKX lines have a reduced content of endogenous CKs and are characterized by a higher number of CRs. Libraries were deep sequenced on Illumina HighSeq platform. Each sample was investigated in three independent biological replicates. Results: Using a data analysis workflow optimized for barley, we identified more than 4000 transcripts differentially expressed in the stem base of 1DAG and 10DAG-seedlings. Expression as determined by RNA-seq was validated by real-time PCR. Our data were compared to the transcriptomic profiling obtained from rice and we were able to identify genes potentially involved in the initiation/development of CRs in barley. Also the use of the transgenic line with altered endogenous CK content allowed us to conclude about the role of CKs in the process. Conclusions: Our study represents the first analysis aiming to understand the initiation and development of CRs in barley.

Expression data from malting barley seeds

Project description:Malting is seed germination under strictly controlled environmental conditions. Malting quality is a complex phenotype that combines a large number of interrelated components, each of which shows complex inheritance. Currently, only a few genes involved in determining malting quality have been characterized. This study combined transcript profiling with phenotypic correlations to identify candidate genes for malting quality. We used the Barley1 GeneChip® array to identify differentially expressed genes in four malting stages relative to dry seed in the barley variety Morex, and to identify differentially expressed genes among four barley varieties. Keywords: time course and genotype differences
