(Submitter supplied) Based on EST-based in silico gene expression analysis a 15k oligonucleotid microarray has been developped in order to monitor environmental stress-dependent gene expression changes in the wheat caryopsis. Using this array, the effect of water withdrawal, with and and without additional heat stress, during the first five days of grain development (0-5 DAA) has been investigated on two wheat cultivars differing in their drought sensitivity. more...

(Submitter supplied) The use of statistical tools established for the genetic analysis of quantitative traits can be applied to gene expression data. Quantitative trait loci (QTL) analysis can associate expression of genes or groups of genes with particular genomic regions and thereby identify regions that play a role in the regulation of gene expression. A segregating population of 41 doubled haploid (DH) lines from the hard red spring wheat cross RL4452 x AC Domain was used. more...

(Submitter supplied) To better undersand the effects of drought stress on wheat developing seeds, the transcription profile of early developing wheat seeds under control and drought stress conditions were comparatively analyzed by using the Affymetrix wheat geneChip. Drought stress is a major yield-limiting factor for wheat. Wheat yields are particularly sensitive to drought stress during reproductive development. Early seed development stage is an important determinant of seed size, one of the yield components. more...

(Submitter supplied) 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.

(Submitter supplied) To provide a global study of transcriptome changes under drought stress, the gene expression levels of a durum wheat genotype (Triticum durum Desf. cultivar Creso) and two bread wheat genotypes (Triticum aestivum L. cultivar Chinese Spring -CS- and its deletion line CS_5AL-10) were investigated. The 5A chromosome deletion line (5AL-10) lacks the distal part (43%) of the long arm of chromosome 5A. Each genotype was subjected to two different levels of water stress at the grain filling stage. more...

(Submitter supplied) The invasive marine mussel Mytilus galloprovincialis has displaced the native congener Mytilus trossulus from central and southern California, but the native species remains dominant at more northerly sites that have high levels of freshwater input. To determine the extent to which interspecific differences in physiological tolerance to low salinity might explain limits to the invasive species’ biogeography, we used an oligonucleotide microarray to compare the transcriptional responses of these two species to an acute decrease in salinity. more...

(Submitter supplied) We monitored gene expression response of the symbiotic sea anemone Anemonia viridis subjected to a thermal and/or UV stress. A symbiosis-dedicated oligonucleotide microarray (2000 selected features) was generated, representing to date the only available oligonucleotide array used for symbiotic cnidarians (GPL10546). We are describing here the expression evolution during the first phase (5 days) of the stress.
