Project description:Determination of changes in expression of genes and pathways as a consequence of drought treatment and following rewatering in barley cv. Golden Promise. RNAs were collected following stomatal closure (theta-critical point) and following rewatering from leaves as well as under fully watered conditions. The plants were grown under greenhouse conditions.
Project description:Wild-type barley cv Golden Promise and two independent RNAi knockdown lines (W1-1 And W1-7) of the WHIRLY1 gene were grown under controlled environments. Leaves were harvested after 7 or 14 days and sampled along a developmental gradient of base, mid and tip. Microarray analysis was conducted from three biological replicates using a custom designed Agilent barley microarray. Analysis of transcript abundance suggests developmental delay in WHIRLY knockdown lines with significant disruption of plastid development and transcription.
Project description:We measured mRNA abundance in the seedling leaves of the barley genotypes Golden Promise and Morex and in F1 hybrids generated using either Golden Promise as a maternal genotype and Morex as paternal or other way around. 3 biological replicates each, total 12 chips.
Project description:Expression Data of Barley Crown and Growing Point Tissue Under Salt Stress abd JA treatment Experiment Overall Design: Barley genotype Golden Promise was used for expression anlaysis using the tissue from crown and growing point under control, salt stressed, JA treatment and JA pretreatment followed by salt stress
Project description:Salt Stress response of salt-tolerant genotype Golden Promise compared to Maythorpe Barley1 GeneChip was used to find differential expression between two barley genotypes under control and salt stress conditions at vegetative stage of growth Keywords: genotype and treatment comparison
Project description:Wild type Golden Promise barley and the frost tolerant TaCBF14 and TaCBF15 transgenic barley lines were grown in plant growth chamber in the Phytotron of ELKH ATK Agricultural Institute, Martonvasar, Hungary. After three weeks in control conditions, plants were treated by short-term cold-treatment. Samples were collected under control condition and after the short-term cold-treatment too.
Project description:In this study, possible adverse effects of transgene expression in field-grown barley were assessed in relation to the influence of genetic background and to the impact of interaction with arbuscular mycorrhiza fungi. The deposited microarray data originate from a parallel transcript profiling, metabolome profiling and metabolic fingerprinting approach with the wild type cultivars Golden Promise (GP) and Baronesse (B) as well as barley transgenics with i) seed-specific expression of (1,3-1,4)-ß-glucanase (GluB) being introgressed from the Golden Promise (GP) into the cultivar Baronesse (B) and ii) ubiquitous expression of codon-optimized Trichoderma harzianum endochitinase (ChGP). Our conclusion from the results is that cultivar-specific differences and even the presence of few introgressed alleles exceed the effects on transcriptome and metabolome caused by transgene expression. Mycorrhization was shown to have more prominent effects on the metabolome than on the transcriptome.
Project description:Salt Stress response of salt-tolerant genotype Golden Promise compared to Maythorpe; Barley1 GeneChip was used to find differential expression between two barley genotypes under control and salt stress conditions at vegetative stage of growth Experiment Overall Design: Roots (tips) and shoot (crown and growing point) tissue was used for hybridization to GeneChips
