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.
Project description:Transcriptional profiling of three different genotypes (wheat cv Chinese Spring, and the wheat-rye addition lines 3R and 6R) comparing control and 24h exposure to 200 μM de AlCl3. The goal was to determine the effects of AlCl3 on global gene expression in each genotype and study the differences between them.
Project description:Fusarium Head Blight (FHB) is a disease of wheat and other cereal crops, where Fusarium graminearum and related species infects the wheat inflorescence during and post-anthesis. The fungus produces trichothecene toxins that accumulate in the grain of infected head, and are required for disease spread. Microarrays were used to observe differential gene expression in the uninoculated spikelets of FHB-challenged wheat spikes in three wheat genotypes. A summary of our findings will be published in Plant Pathology.
Project description:Two different wheat genotypes were treated with the high temperature and control conditions under full irrigated condition. Leaf tissues were collected for all 2-different treatments with six replicates after 7 and 10 days of high temperature treatment.
Project description:Transcriptional comparison of developing grains between two wheat genotypes with contrasting levels of minerals in grain, using Affymetrix GeneChip® Wheat Genome Array.
Project description:12plex_wheat_2012-05 - 12plex-wheat_2012-05 - The objective is to better understand the adaptive response of the wheat plant to an elevated mean temperature. Besides the morphological and ecophysiological responses, the changes in the expression of genes are investigated. Two genotypes (SxB49 and SxB139) are subjected to two different temperature regimes during the lag-phase of the developing grains. The profiling of the accumulation of gene transcripts throughout 12 developmental stages is carried out using a custom-designed 12x135K Roche NimbleGen gene expression microarray comprising the most recent NCBI wheat contig assembly and annotation (about 45 000 unigenes). This should permit both the identification of differentially expressed genes after heat treatment and the comparison of the behaviours of two wheat genotypes (SxB139 and SxB49). - The effect of the temperature on the expression of genes along with the effect of genotype
