(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) 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) 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) 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) 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) 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...

(Submitter supplied) Development of wheat (Triticum aestivum L.) grain mainly depends on the processes of starch synthesis and storage protein accumulation, which are critical for grain yield and quality. However, the regulatory network underlying the transcriptional and physiological changes of grain development is still not clear. Here, we combined ATAC-seq and RNA-seq to discover the chromatin accessibility and gene expression dynamics during these processes. more...

(Submitter supplied) Climate change is not only causing a rise of global temperature but also more variable climates. In major wheat-producing countries, spring temperatures have increased up to 40°C in recent years. Considering the wheat optimal growth temperature of around 20°C, wheat is particularly prone to damage by heat stress. To combat this threat, it is imperative to understand the response of wheat to early heat stress. more...

(Submitter supplied) Gluten proteins are responsible for the unique viscoelastic properties of wheat dough, but they also trigger the immune response in celiac disease patients. RNA interference (RNAi) wheat lines with strongly silenced gliadins were obtained to reduce the immunogenic response of wheat. The E82 line presents the highest reductions of gluten, but other grain proteins increased, maintaining a total nitrogen content comparable to that of the wild type. more...
