(Submitter supplied) Six months old seed grown under well-watered greenhouse conditions were used in the current study. The seedlings of the two wild emmer wheat genotypes were vernalized on a moist germination paper (Hofman Manufacturing, Inc, Jefferson, OR, USA) for three weeks in the dark at 4oC, followed by three days acclimation at 24oC. Seedlings were then transplanted into 5L pots containing a mixture of pure quartz sand and peat (4:1 v/v), supplemented with a slow release fertilizer (2 g/L, Osmocote® Standard 14-14-14, Scotts-Sierra Horticulture, Marysville, OH, USA) and by a weekly application of 100 ml/pot of 0.5X Murashigi and Skoog growth solution (Sigma Chemical Co., St Louis, MO, USA). more...

(Submitter supplied) Genome-wide Transcriptional Analysis of Genes Associated with Drought Stress in Gossypium herbaceum root This experiment was designed to investigate the molecular mechanism associated with drought tolerance in root tissue of Gossypium herbaceum. The gene expression profiles of the root tissue using Affymetrix Cotton Genome Array were compared with drought tolerant and drought sensitive genotype of G.herbaceum under drought stress and watered condition. more...

(Submitter supplied) Wheat cultivars ‘TAM 111’ and ‘TAM 112’ have been dominantly grown in the Southern U.S. Great Plains for many years due to their excellent, yet variable, drought tolerance. To identify the molecular basis and genetic control of drought tolerance in these two landmark cultivars, RNA-seq analysis was conducted to compare gene expression difference in flag leaves under fully irrigated (wet) and water deficient (dry) conditions. more...

(Submitter supplied) Jatropha curcas, a multipurpose plant attracting much attention due to its high oil content and quality for biofuel, is recognized as a drought tolerant species. However, this drought tolerance is still poorly characterized. This study aims to contribute to uncover the molecular background of this tolerance, with the use of a combined approach of transcriptional profiling and morphophysiological characterization along a period of water withholding (49 days) followed by rewatering (7 days). more...

(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) Two durum wheat (Triticum turgidum L. var. durum) genotypes, the variety Borgia (derived from the cross IRTA-1004 x Bidi 17) and a pale-green mutant (MD-597) derived from it, were used for the measurement of physiological traits and gene expression. Mutant plants used for this study were the stable eight generation (M8) derived from the isolated original mutant plant. Terminal water stress: irrigation was drastically reduced from the booting stage until maturity by watering the pots with the amount of water necessary to maintain the pots at 1/3 of field capacity. more...

(Submitter supplied) The aim of the study was to identify candidate genes responsible for drought tolerance trait between a pair of wheat varieties ( WL711 and C306) and correspondng progeny bulks (10 drought susceptible RILs and 10 drought tolerant RILs) by combining QTLs analysis with expression analysis. Microarray analysis of RNA extracted from the flag leaves showed large number of differentially expressed genes. more...

(Submitter supplied) Plant survival in adverse environmental conditions requires a substantial change in the metabolism, which is reflected by the extensive transcriptome rebuilding upon the occurrence of the stress. Therefore, transcriptomic studies offer an insight into the mechanisms of plant stress responses. Here, we present the results of global gene expression profiling of roots and leaves of two barley genotypes with contrasting ability to cope with drought stress. more...

(Submitter supplied) More than four billion people rely on bread wheat (Triticum aestivum L.) as a major constituent of their diet. However, the changing climate threatens wheat production, with periods of intense drought stress already causing widespread wheat yield losses. Much of the research into the wheat drought response has centred on the response to drought events later in development, during anthesis or grain filling. more...
