Common oat (Avena sativa) is an important cereal crop serving as a valuable source of forage and human food. Although reference genomes many crops have been generated, such work in has lagged behind, primarily owing to its large, repeat-rich polyploid genome. Here, using Oxford Nanopore ultralong sequencing Hi-C technologies, we generated reference-quality genome assembly hulless common oat, comprising 21 pseudomolecules with total length 10.76 Gb contig N50 75.27 Mb. We also produced...
Pre-harvest sprouting (PHS) is mainly caused by the breaking of seed dormancy in high rainfall regions, which leads to huge economic losses wheat. In this study, we evaluated 717 Chinese wheat landraces for PHS resistance and carried out genome-wide association studies (GWAS) using 9,740 DArT-seq 178,803 SNP markers. Landraces were grown across six environments China germination testing harvest-ripe grain was used calculate rate (GR) each accession at site. GR highly correlated all...
Summary Pre‐harvest sprouting (PHS), the germination of grain before harvest, is a serious problem resulting in wheat yield and quality losses. Here, we mapped PHS resistance gene PHS‐3D from synthetic hexaploid to 2.4 Mb presence–absence variation (PAV) region found that its effect was attributed pleiotropic Myb10‐D by integrated omics functional analyses. Three haplotypes were detected this PAV among 262 worldwide lines 16 Aegilops tauschii , percentages containing approximately 40% lower...
Summary Plant transcription factors (TFs), such as basic helix‐loop‐helix (bHLH) and AT‐rich zinc‐binding proteins (PLATZ), play critical roles in regulating the expression of developmental genes cereals. We identified bHLH protein TaPGS1 ( T. aestivum Positive Regulator Grain Size 1) specifically expressed seeds at 5–20 days post‐anthesis wheat. was ectopically overexpressed (OE) wheat rice, leading to increased grain weight (up 13.81% 18.55% rice lines) size. Carbohydrate total levels also...
The MADS-box genes encode transcription factors with key roles in plant growth and development. A comprehensive analysis of the gene family bread wheat (Triticum aestivum) has not yet been conducted, our understanding their stress is rather limited. Here, we report identification characterization wheat. total 180 classified as 32 Mα, 5 Mγ, Mδ, 138 MIKC types were identified. Evolutionary orthologs among T. urartu, Aegilops tauschii well homeologous sequences three sub-genomes revealed that...
Micronutrient malnutrition affects over three billion people worldwide, especially women and children in developing countries. Increasing the bioavailable concentrations of essential elements edible portions crops is an effective resolution to address this issue. To determine genetic factors controlling micronutrient concentration wheat, quantitative trait locus (QTL) analysis for iron, zinc, copper, manganese, selenium two recombinant inbred line populations was performed. In all, 39 QTLs...
Wheat was introduced to China approximately 4500 years ago, where it adapted over a span of time various environments in agro-ecological growing zones. We investigated 717 Chinese and 14 Iranian/Turkish geographically diverse, locally wheat landraces with 27 933 DArTseq (for landraces) 312 831 Wheat660K subset 285 markers. This study highlights the adaptive evolutionary history cultivation China. Environmental stresses independent selection efforts have resulted considerable genome-wide...
Stripe rust is a serious fungal disease of wheat (Triticum aestivum L.) caused by Puccinia striiformis f. sp. tritici (Pst), which results in yield reduction and decreased grain quality. Breeding for genetic resistance to stripe the most cost-effective method control disease. In present study, genome-wide association study (GWAS) was conducted identify markers linked genes (or loci) 93 Northern Chinese landraces, using Diversity Arrays Technology (DArT) simple sequence repeat (SSR) molecular...
Stripe rust (also called yellow rust) is a common and serious fungal disease of wheat (Triticum aestivum L.) caused by Puccinia striiformis f. sp. tritici. The narrow genetic basis modern cultivars rapid evolution the pathogen have been responsible for periodic devastating epidemics diseases. In this study, we conducted genome-wide association study with 44,059 single nucleotide polymorphism markers to identify loci associated resistance stripe in 244 Sichuan accessions, including 79...
Stripe rust (also known as yellow rust), caused by the pathogen Puccinia striiformis f. sp. Tritici (Pst), is a common and serious fungal disease of wheat (Triticum aestivum L.) worldwide. To identify effective stripe resistance loci, genome-wide association study was performed using 152 landraces from Yellow Huai River Valleys in China, with Diversity Arrays Technology simple sequence repeat markers. Phenotypic evaluations levels to at adult-plant stage under field conditions were carried...
Kernel length (KL), kernel width (KW) and thousand-kernel weight (TKW) are key agronomic traits in wheat breeding. Chuannong16 ('CN16') is a commercial cultivar with significantly longer kernels than the line '20828'. To identify characterize potential alleles from CN16 controlling KL, previously developed recombinant inbred (RIL) population derived cross '20828' × 'CN16' genetic map constructed by Wheat55K SNP array SSR markers were used to perform quantitative trait locus/loci (QTL)...
Wheat grain serves as the primary raw material for producing medium-high temperature (MT)-Daqu, a fermentation starter crucial Chinese Baijiu production, characterized by spontaneous without inoculation of exogenous substances. However, interactions among wheat varieties, cultivation environments, and resulting Daqu quality remain poorly understood. This study evaluates three varieties harvested from distinct examining quality, grain-associated endophytes, physicochemical properties...
Phytopathogens such as Puccinia striiformis f. sp. tritici (Pst) induce pigment retention at pathogen infection sites. Although is commonly observed in diverse pathosystems, its underlying physiological mechanism remains largely unclear. Herein, we identify and characterize a wheat leaf senescence gene, TaSGR1, which enhances resistance against Pst by promoting H2O2 accumulation while inhibiting photosynthesis. Knockout of TaSGR1 (STAYGREEN) increases plant susceptibility. Pst_TTP1...
Abstract Background High-molecular-weight glutenin subunits (HMW-GSs) have been considered as most important seed storage proteins for wheat flour quality. 1Ay are of great interest because they always silent in common wheat. The presence expressed diploid and tetraploid genotypes makes it possible to investigate molecular information active genes. Results We identified with different electrophoretic mobility from 141 accessions wheats, obtained the complete ORFs 5' flanking sequences genes...
