Abstract Background MicroRNAs (miRNAs) are a class of small non-coding regulatory RNAs that regulate gene expression by guiding target mRNA cleavage or translational inhibition. MiRNAs can have large-scale effects on development and stress response in plants. Results To test whether miRNAs play roles regulating to powdery mildew infection heat wheat, using Solexa high-throughput sequencing we cloned the RNA from wheat leaves infected preponderant physiological strain Erysiphe graminis f. sp....
Hexaploid wheat (Triticum aestivum) is a globally important crop. Heat, drought and their combination dramatically reduce yield quality, but the molecular mechanisms underlying tolerance to extreme environments, especially stress combination, are largely unknown. As an allohexaploid, consists of three closely related subgenomes (A, B, D), was reported show improved conditions compared tetraploid. But so far very little known about how coordinates expression homeologous genes cope with...
Abstract Background Biotic and abiotic stresses, such as powdery mildew infection high temperature, are important limiting factors for yield grain quality in wheat production. Emerging evidences suggest that long non-protein coding RNAs (npcRNAs) developmentally regulated play roles development stress responses of plants. However, identification npcRNAs is limited to a few plant species, Arabidopsis, rice maize, no systematic their biotic stresses reported wheat. Results In this study, by...
Abstract Tibetan wheat is grown under environmental constraints at high-altitude conditions, but its underlying adaptation mechanism remains unknown. Here, we present a draft genome sequence of semi-wild ( Triticum aestivum ssp. tibetanum Shao) accession Zang1817 and re-sequence 245 accessions, including world-wide landraces, cultivars as well landraces.

In wheat (Triticum aestivum L.), breeding efforts have focused intensively on improving grain yield and quality. For quality, the content composition of seed storage proteins (SSPs) determine elasticity dough flour processing Moreover, starch levels in seeds are associated with yield. However, little is known about mechanisms that coordinate SSP accumulation wheat. this study, we explored role endosperm-specific NAC transcription factor TaNAC019 coordinating accumulation. binds to promoters...
Abstract Polyploidy occurs prevalently and plays an important role during plant speciation evolution. This phenomenon suggests polyploidy could develop novel features that enable them to adapt wider range of environmental conditions compared with diploid progenitors. Bread wheat (Triticum aestivum L., BBAADD) is a typical allohexaploid species generally exhibits greater salt tolerance than its tetraploid progenitor (BBAA). However, little known about the underlying molecular basis regulatory...
Abstract Modern green revolution varieties of wheat ( Triticum aestivum L.) confer semi-dwarf and lodging-resistant plant architecture owing to the Reduced height-B1b Rht-B1b ) Rht-D1b alleles 1 . However, both are gain-of-function mutant encoding gibberellin signalling repressors that stably repress growth negatively affect nitrogen-use efficiency grain filling 2–5 Therefore, harbouring or usually produce smaller require higher nitrogen fertilizer inputs maintain their yields. Here we...
Heat stress greatly threatens crop production. Plants have evolved multiple adaptive mechanisms, including alternative splicing, that allow them to withstand this stress. However, how splicing contributes heat responses in wheat (Triticum aestivum) is unclear. We reveal the shock transcription factor gene TaHSFA6e alternatively spliced response generates two major functional transcripts: TaHSFA6e-II and TaHSFA6e-III. TaHSFA6e-III enhances transcriptional activity of three downstream protein...
Exposure to temperatures exceeding the normal optimum levels, or heat stress (HS), constitutes an environmental disruption for plants, resulting in severe growth and development retardation. Here we show that loss of function Arabidopsis histone acetyltransferase GCN5 results serious defects terms thermotolerance, considerably impairs transcriptional activation HS-responsive genes. Notably, expression several key regulators such as HS transcription factors HSFA2 HSFA3, Multiprotein Bridging...
Summary Plant can acquire tolerance to environmental stresses via transcriptome reprogramming at transcriptional and alternative splicing ( AS ) levels. However, how coordinates with regulation contribute abiotic responses is still ambiguous. In this study, we performed genome‐wide analyses of drought stress DS ), heat HS their combination HD in wheat seedlings, further compared them responses. total, found 200, 3576 4056 genes exhibiting significant pattern changes response , respectively,...
Major advances in wheat production are needed to address global food insecurity under future climate conditions, such as high temperatures. The grain yield of bread (Triticum aestivum L.) is a quantitatively inherited complex trait that strongly influenced by interacting genetic and environmental factors. Here, we conducted QTL analysis for five yield-related traits, including spike yield, components plant height (PH), the Nongda3338/Jingdong6 doubled haploid (DH) population using...
Summary Excess soluble salts in soil are harmful to the growth and development of most plants. Evidence is emerging that plant cell wall involved sensing responding salt stress, but underlying mechanisms not well understood. We reveal histone acetyltransferase General control non‐repressed protein 5 ( GCN 5) required for maintenance integrity stress tolerance. The levels mRNA increased response stress. gcn5 mutants exhibited severe inhibition defects under conditions. Combining RNA...
The yield of wheat (Triticum aestivum L.), an important crop, is adversely affected by heat stress in many regions the world. However, molecular mechanisms underlying thermotolerance are largely unknown. A novel ferritin gene, TaFER, was identified from our previous stress-responsive transcriptome analysis a heat-tolerant cultivar (TAM107). TaFER mapped to chromosome 5B and named TaFER-5B. Expression pattern revealed that TaFER-5B induced heat, polyethylene glycol (PEG), H2O2...
As a cool season crop, wheat (Triticum aestivum L.) has an optimal daytime growing temperature of 15 °C during the reproductive stage. With global climate change, heat stress is becoming increasingly severe constraint on production. In this review, we summarize recent progress in understanding molecular mechanisms tolerance wheat. We firstly describe impact morphology and physiology its potential effect agronomic traits. then review discoveries determining genetic factors affecting...
A novel TaGW2-A1 allele was identified from a stable, robust QTL region, which is pleiotropic for thousand grain weight, number per spike, and morphometric parameters in wheat. Thousand weight (TGW) spike (GNS) are two crucial determinants of wheat yield, genetic dissection their relationships can help to fine-tune these components maximize yield. By evaluating 191 recombinant inbred lines 11 field trials, we five genomic regions on chromosomes 1B, 3A, 3B, 5B, or 7A that solely influenced...
Seed germination is important for grain yield and quality rapid, near-simultaneous helps in cultivation; however, cultivars that germinate too readily can undergo preharvest sprouting (PHS), which causes substantial losses areas tend to get rain around harvest time. Moreover, our knowledge of mechanisms regulating seed wheat (Triticum aestivum) remains limited. In this study, we analyzed function a wheat-specific microRNA 9678 (miR9678), specifically expressed the scutellum developing...
