(Submitter supplied) 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. 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) To dissect the molecular mechanisms underlying drought tolerance (DT) in rice, transcriptome differences of a DT introgression line H471, the DT donor P28 and the drought sensitive recurrent parent HHZ under drought stress were investigated using deep transcriptome sequencing. Results revealed a differential constitutive gene expression prior to stress and distinct global transcriptome reprogramming among three genotypes under time-series drought stress, consistent with their differential genotypes and DT phenotypes.

(Submitter supplied) The combined heat and drought stress influence the plant growth and development. Switchgrass is an economically important crop due to the availability of high biomass with little water and nutrient requirements. Earlier reports suggested that switchgrass growth and yield highly influenced by heat and drought. The mechanism behind heat and drought stress is not fully understood in switchgrass. This study has undertaken to analyze the epigenetic modification using ChIP-Seq analysis with the activation histone mark H3K4me3. more...

(Submitter supplied) Purpose: Increasing biomass yield and quality of feedstock have been a recent interest in switchgrass research. Despite the economic importance of switchgrass, increasing temperature and water deficit are limiting factors to the cultivation of bioenergy crops in the semi-arid areas. The effect of individual drought or heat stress has been studied separately in switchgrass. However, there is relatively limited or no report on the molecular basis of combined abiotic stress tolerance in switchgrass particularly the combination of drought and heat stress. 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) Water-deficit and heat stress negatively impact crop production. Mechanisms underlying the response of durum wheat to such stresses are not well understood. With the new durum wheat genome assembly, we conducted the first multi-omics analysis with next-generation sequencing, providing a comprehensive description of the durum wheat small RNAome (sRNAome), mRNA transcriptome, and degradome. Single and combined water-deficit and heat stress were applied to stress-tolerant and -sensitive Australian genotypes to study their response at multiple time-points during reproduction. more...

(Submitter supplied) Traditional rice varieties found in India have many desirable characteristics. Amongst them, their differential responses to abiotic and biotic stresses are of great agricultural importance. Drought or osmotic stress is one of the major abiotic stresses afflicting crop plants in India. Indigenous varieties like Dagad deshi have been found to be drought resistant and, thereby, are being studied in great detail by plant breeders and biotechnologists alike. 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) Background: MicroRNAs are endogenous small noncoding RNAs that play critical roles in plant abiotic stress responses. The interaction between miRNA-mRNA targets and their regulatory pathways in response to water deficit stress has been investigated in many plant species. However, the miRNA transcriptome of durum wheat (Triticum turgidum L. ssp. durum) is poorly characterised, with little known about miRNA functions related to water deficit stress. more...
