(Submitter supplied) Durum wheat (Triticum turgidum subsp. durum) is widely grown for pasta production, and more recently, is gaining additional interest due to its resilience to warm, dry climates and its use as an experimental model for wheat research. To enable further research into endosperm development and storage reserve synthesis, we generated a high-quality transcriptomics dataset from developing endosperms of durum variety Kronos, to complement the extensive mutant resources available for this variety. more...

(Submitter supplied) Wheat is one of the most significant crops in terms of human consumption in the world. In a climate change scenario, extreme weather event such as heatwaves will be more frequent especially during the grain-filling (GF) stage and could affect grain weight and quality of crops. Molecular mechanisms underlying the response to short heat stress (HS) have been widely reported for the hexaploid wheat (Triticum aestivum) but the regulatory heat stress mechanisms in tetraploid durum wheat (Triticum turgidum ssp. more...

(Submitter supplied) Heat stress is a major limiting factor for grain yield and grain quality in wheat production. In crops, abiotic stresses have transgenerational effects and the mechanistic basis of stress memory is associated with epigenetic regulation. The current study presents the first systematic analysis of the transgenerational effects of post-anthesis heat stress in tetraploid wheat. Genotype-dependent response patterns to parental and progeny heat stress were found for the leaf physiological traits, harvest components, and grain quality traits measured. more...

(Submitter supplied) 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. more...

(Submitter supplied) Water-deficit stress negatively affects wheat yield and quality. Abiotic stress on the parental plants during reproduction could have transgenerational effects on the progenies. Here we investigated the transgenerational influence of pre-anthesis water-deficit stress by detailed analysis of the yield components, grain quality traits, and physiological traits in durum wheat. Next-generation sequencing analysis profiled the small RNA-omics, mRNA transcriptomics, and mRNA degradomics in the progenies. more...

(Submitter supplied) Crop reproduction is highly sensitive to water-deficit and heat stress. The molecular networks of stress adaptation and grain development in tetraploid wheat (T. turgidum durum) are not well understood. Small RNAs (sRNAs) are important epigenetic regulators connecting the transcriptional and post-transcriptional regulatory networks. This study presents the first multi-omics analysis of the sRNAome, transcriptome and degradome in T. 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) Water deficiency and heat stress can severely limit crop production and quality. Stress imposed on the parents during reproduction could have transgenerational effects on their progeny. Seeds with different origins can vary significantly in germination time-course and early growth. Here, we investigated how water-deficit and heat stress on parental durum wheat plants affected seedling establishment of the subsequent generation. 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) 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) 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...
