Gene expression profile of the developing endosperm in durum wheat provides insight into starch biosynthesis

(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...

Transcriptomic and physiological response of durum wheat grain to short period of heat stress at the early grain-filling stage

(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...

Small RNA, transcriptome and degradome analysis of the transgenerational heat stress response network in durum wheat

(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...

Nitrogen starvation-responsive microRNAs are affected by transgenerational stress in durum wheat seedlings

(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...

Small RNAs and their targets are associated with the transgenerational effects of water-deficit stress in durum wheat

(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...

Multi-omics analysis of small RNA, transcriptome and degradome in T. turgidum – regulatory networks of grain development and abiotic stress response

(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...

Integrated Analysis of Small RNA, Transcriptome, and Degradome Sequencing Reveals the Water-Deficit and Heat Stress Response Network in Durum Wheat

(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...

Transgenerational effects of water-deficit and heat stress on germination and seedling vigour – new insights from durum wheat microRNAs

(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...

PHYB and PHYC–mediated transcriptomic responses to short and long day photoperiods in wheat

(Submitter supplied) The phytochromes (PHYs) are a family of photoreceptors which absorb red and far-red light to modulate developmental responses in photosynthetic organisms. We developed knockout mutants of PHYB and PHYC in tetraploid wheat and performed RNA-seq studies to analyze and compare the regulons of each phytochrome under short day photoperiods.

Drought, heat and combined stress in durum wheat

(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...

Transcriptome modification to the BBAA subgenomes of common wheat since allohexaploidization is largely irreversible

(Submitter supplied) The three subgenomes (B, A and D) of common wheat (2n=6x=42) are largely intact, which makes extraction of the BBAA subgenomes as organismally independent genomes possible. Availability of such novel extracted tetraploid wheat (Extracted-tetra) provides a unique opportunity to study whether and to what extent the BBAA subgenomes of common wheat have been irreversibly modified, as well as its attendant biological consequences, during their evolutionary trajectory as allohexaploidy. more...

Genome-wide identification of differentially expressed microRNAs in leaves and the developing head of four durum genotypes during water deficit stress

(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...

Regulation of Zn and Fe transporters by the GPC1 gene during wheat monocarpic senescence

(Submitter supplied) TaGPC1 and TaGPC2 are NAC-domain transcription factors which accelerate the onset of senescence and facilitate nutrient translocation in wheat. We developed knockout mutants of these genes in tetraploid wheat and used RNA-seq to identify the effect of these mutations on the wheat flag leaf transcriptome during monocarpic senescence. Several transporter-related genes were identified which were upregulated during senescence and differentially expressed between genotypes.
