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. Developing barley caryopses were harvested at different time-points of a day during heat stress (42M-BM-0C) (2:00 PM, 5:00 PM and 8:00 PM). Heat stress started at 1:30PM. Pooled caryopses (form 3 plants) from the respective time points were used for RNA extraction and hybridization on Affymetrix microarrays (Barley1 GeneChip; GEO accsession GPL1340). Biological replicates were performed.

Project description:Caryopses of barley (Hordeum vulgare), like all other cereal seeds, are complex sink organs optimized for storage starch accumulation and embryo development. Their development from early stages after pollination to late stages of seed ripening has been studied in great detail. However, information on the caryopses’ diurnal adaptation to changes in light, temperature and alterations in phloem-supplied carbon and nitrogen remained unknown. In this study, we applied the 22K Barley1 GeneChip microarray to investigate diurnal gene regulation events of barley caryopses at 11 to 12 days post anthesis.

Project description:Drought tolerance is a key trait for increasing and stabilizing barley productivity in dry areas worldwide. Identification of the genes responsible for drought tolerance in barley (Hordeum vulgare L.) will facilitate understanding of the molecular mechanisms of drought tolerance, and also genetic improvement of barley through marker-assisted selection or gene transformation. To monitor the changes in gene expression at transcription levels in barley leaves during the reproductive stage under drought conditions, the 22K Affymetrix Barley 1 microarray was used to screen two drought-tolerant barley genotypes, Martin and Hordeum spontaneum 41-1 (HS41-1), and one drought-sensitive genotype Moroc9-75. Seventeen genes were expressed exclusively in the two drought-tolerant genotypes under drought stress, and their encoded proteins may play significant roles in enhancing drought tolerance through controlling stomatal closure via carbon metabolism (NADP malic enzyme (NADP-ME) and pyruvate dehydrogenase (PDH), synthesizing the osmoprotectant glycine-betaine (C-4 sterol methyl oxidase (CSMO), generating protectants against reactive-oxygen-species scavenging (aldehyde dehydrogenase (ALDH), ascorbate-dependant oxidoreductase (ADOR), and stabilizing membranes and proteins (heat-shock protein 17.8 (HSP17.8) and dehydrin 3 (DHN3). Moreover, 17 genes were abundantly expressed in Martin and HS41-1 compared with Moroc9-75 under both drought and control conditions. These genes were likely constitutively expressed in drought-tolerant genotypes. Among them, 7 known annotated genes might enhance drought tolerance through signaling (such as calcium-dependent protein kinase (CDPK) and membrane steroid binding protein (MSBP), anti-senescence (G2 pea dark accumulated protein GDA2) and detoxification (glutathione S-transferase (GST) pathways. In addition, 18 genes, including those encoding Δl-pyrroline-5-carboxylate synthetase (P5CS), protein phosphatase 2C-like protein (PP2C) and several chaperones, were differentially expressed in all genotypes under drought; thus, they were more likely general drought-responsive genes in barley. These results could provide new insights into further understanding of drought-tolerance mechanisms in barley.

Project description:The present transcript profiling compares the gene expression during cold-acclimation in different genotypes of barley (Hordeum vulgare L.), wheat (Triticum aestivum L.) and rye (Secale cereale L.) in order to determine factors influencing frost tolerance. Because of its outstanding robustness against adverse environmental conditions rye is considered to be a model species for abiotic stress tolerance. Wheat is moderate frost-tolerant and barley is most sensitive species in this study. The aim of this study elucidate conserved, as well as, species-specific gene regulation across the Triticeae. Furthermore, transcript abundances were correlated between the distinct frost tolerances of genotypes within each species in order to find candidate genes for frost tolerance.
