Project description: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. After anthesis, three different levels of soil water content (SWC) were induced as described below: control (CTRL; SWC=28%), moderate stress (MS; SWC=18%), and severe stress (SS; SWC=12.5%). For each sample, three biological replicates were performed, for a total of 27 hybridizations. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Alessio Aprile.

Project description:Durum wheat is an important cereal crop grown mainly in semi-arid environments (e.g. Mediterranean regions) characterized by water scarcity and high temperatures often occurring at the same time. This work reports on a transcriptomic analysis carried out on two durum wheat cultivars (Cappelli and Ofanto) characterized by different water use efficiency (WUE), grown to booting stage and subjected to a combination of drought and heat stresses, a situation similar to the experience of a crop grown in Mediterranean environments and exposed to a terminal heat/drought stress. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, alessio.

Project description:Plant material consisted of synthetic hexaploid wheat germplasm into the Opata background (Altar 84/ Aegilops squarrosa (TAUS)//Opata) . Plants were grown at a density of 9-11 individuals per 20cm x 10cm (diameter x height) plastic pot containing 1500g well-rinsed Turface MVP® medium (Profile Products LLC, Buffalo, IL), in controlled environment chambers at 23°C, 70% relative humidity, and 16h photoperiod with a photosynthetic photon flux (PPF) of 330±10 µmolem-2s-1 when measured at the top of the canopy at growth stage 22 to 24 in the Zadoks scale (Zadoks et al., 1974). Plants were watered daily until 21 days after seeding (DAS) by flooding trays with water for 5 minutes, then draining the trays. Drought stress was applied by water withholding, beginning on 21 DAS. Watering was withheld from plants belonging to drought treatment, while the control group received water above field capacity. Water content of the growth medium was gravimetrically monitored. Root tissues were collected from control and treated plants when the water content of the treatment group growth medium fell below the permanent wilting point. Three biological replicates were conducted in three separate time-span courses. Total RNA was isolated using a LiCl3 precipitation method following Moore et al., (2005). Dye swap desin microarray analyses of well-watered and water-stressed root tissues were conducted across three biological replicates totaling six hybridizations.

Project description: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. The drought treatment was started by withholding water at the anthesis stage. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Alessio Aprile.

Project description:A global, systems-based study of the transcriptome response of three drought resistant durum wheat genotypes to water stress. Two parents of a mapping population (Lahn x Cham 1) and a recombinant inbred line (RIL2219), selected for their drought resistance in multiyear field trials, were subjected to controlled time series water stress and samples taken over a six day period to study flag leaf gene expression in parallel with physiological measurements. The aim was to dissect the responses to water stress in an attempt to identify molecular and physiological properties defining stress resistance and thus to build knowledge to accelerate the breeding effort.

Project description:Stress events have transgenerational effects that influence plant growth in the subsequent generation. In Mediterranean regions, water-deficit and heat (WH) stress is a frequent issue that negatively affects crop yield and quality. Nitrogen (N) is an essential plant macronutrient and often a yield-limiting factor for crops. Here, the response of durum wheat seedlings to N starvation under the transgenerational effects of WH stress were investigated in two genotypes. Both genotypes showed significant reduction in seedling height, leaf number, shoot and root weight (fresh and dry), primary root length and chlorophyll content under N starvation stress. However, in the WH stress-tolerant genotype, the reduction rate of most traits were lower in progeny from the stressed parents than progeny from the control parents. Small RNA sequencing identified 1,534 microRNAs in different treatment groups. Differentially expressed microRNAs (DEMs) were characterized subject to N starvation, parental stress and genotype factors, with their target genes identified in silico. GO and KEGG enrichment analyses revealed the biological functions associated with DEM-target modules in stress adaptation processes, which could contribute to the phenotypic differences observed in two genotypes. The study provides the first evidence of the transgenerational effects of WH stress on N starvation response in durum wheat.
