Fungal disease meets its match Fusarium head blight (FHB), caused by a fungus, reduces wheat crop yield and introduces toxins into the harvest. From assembly of genome Thinopyrum elongatum , wild relative used in breeding programs to improve cultivated wheat, Wang et al. cloned gene that can address both problems (see Perspective Wulff Jones). The encoded glutathione S -transferase detoxifies trichothecene toxin and, when expressed confers resistance FHB. Science this issue p. eaba5435 ; see also 822
Glutathione S-transferases (GSTs) are ancient proteins encoded by a large gene family in plants, which play multiple roles plant growth and development. However, there has been little study on the GST genes of common wheat (Triticum aestivum) its relatives durum, Triticum urartu, Aegilops tauschii), four important species Triticeae. Here, genome-wide comprehensive analysis this was performed genomes relatives. A total 346 T. aestivum, 226 104 105 Ae. tauschii were identified, all members...
In plants, the mechanism for ecological sympatric speciation (SS) is little known. Here, after ruling out possibility of secondary contact, we show that wild emmer wheat, at microclimatically divergent microsite "Evolution Canyon" (EC), Mt. Carmel, Israel, underwent triple SS. Initially, it split following a bottleneck an ancestral population, and further diversified to three isolated populations driven by disruptive selection. Remarkably, two postzygotically (SFS1 SFS2) sympatrically...
Bread wheat (Triticum aestivum) is an important staple cereal grain worldwide. The ever-increasing environmental stress makes it very to mine stress-resistant genes for breeding programs. Therefore, dehydrin (DHN) can be considered primary candidates such programs, since they respond multiple stressors.In this study, we performed a genome-wide analysis of the DHN gene family in genomes and its three relatives. We found 55 T. aestivum, 31 dicoccoides, 15 urartu, 16 Aegilops tauschii....
Bread wheat (Triticum aestivum) is a staple food crop worldwide. The genetic dissection of important nutrient traits essential for the biofortification to meet nutritional needs world's growing population. Here, 45298 single-nucleotide polymorphisms (SNPs) from 55K chip arrays were used genotype panel 768 cultivars; total 154 quantitative trait loci (QTLs) detected eight under three environments by genome-wide association study (GWAS). Three QTLs (qMn-3B.1, qFe-3B.4, and qSe-3B.1/qFe-3B.6)...
Fusarium head blight (FHB), a serious disease in wheat, causes significant reductions grain yield and quality worldwide. Marker-assisted selection can provide an effective tool for improving FHB resistance. Although many quantitative trait loci associated with resistance to have been reported, few are currently available breeding programs. The middle lower reaches of the Yangtze River China areas that historically experienced epidemics, so some local varieties may contain valuable genes...
Fhb7 is a major gene that was transferred from Thinopyrum ponticum to chromosome 7D of wheat (Triticum aestivum) and confers resistance both Fusarium head blight (FHB) crown rot (FCR). However, tightly linked the PSY-E2 gene, which causes yellow flour, limiting its application in breeding. To break this linkage, marker K-PSY developed for tagging used with markers identify recombination between two genes. Screening 21,000 BC1F2 backcross progeny (Chinese Spring ph1bph1b*2/SDAU 2028) revealed...
Grain size is a key trait associated with bread wheat yield. It also the most frequently selected during domestication. After phenotypic characterization of 768 accessions in three plots for at least two years, present study shows that improved variety showed significantly higher grain but lower protein content than landrace. Using 55K SNP assay genotyping and large-scale phenotyping population GWAS data, we identified 5, 6, 6 QTLs length, weight, area, thousand respectively. Seven 23 common...
Wheat has a large and diverse repertoire of NLRs involved in disease resistance, with over 1,500 detected some studies. These NLR genes occur as singletons or clusters containing copies from different phylogenetic clades. The number cluster size can differ drastically among ecotypes cultivars. Primarily, duplication led to the evolution diversification genes. Among various mechanisms, whole genome (WGD) is most intense leading cause, contributing complex evolutionary history abundant gene...
Wheat powdery mildew is a fungal disorder caused by Blumeria graminis f. sp. tritici (Bgt) and severe significant threat to the yield quality of its host. The most practical environmentally friendly approach controlling this disease through resistance gene identification develop resistant varieties. Wild germplasm relatives wheat are valuable reservoir genes contributing against mildew. In our study, we identified Aegilops tauschii “KU-2013”, exhibiting seedling Bgt isolate E09 following...
Plant epidermis serves important functions in shoot growth, plant defense and lipid metabolism, though mechanisms of related transcriptional regulation are largely unknown. Here, we identified cis-elements specific to expression by dissecting the promoter Triticum aestivum transfer protein 1 (TaLTP1). A preliminary deletion analysis revealed that a truncated fragment within 400 bp upstream from translation start site was sufficient confer conserved epidermis-specific transgenic Brachypodium...
Even frequently used in wheat breeding, we still have an insufficient understanding of the biology products via distant hybridization. In this study, a transcriptomic analysis was performed for six Triticum aestivum - Thinopyrum elongatum substitution lines comparison with host plants. All disomic showed much stronger “transcriptomic-shock” occurred on alien genomes 57.43–69.22% genes changed expression level but less recipient genome (2.19–8.97%). Genome-wide suppression along chromosomes...
Abstract Background: Bread wheat ( Triticum aestivum ) is an important and fundamental cereal worldwide. With increasingly severe environmental stress, it very to mine stress-resistant genes for breeding. Dehydrin (DHN) are primary candidates because they involved in the response many stressors. Results: Here, a genome-wide analysis of this gene family was performed on genomes its three relatives. A total 55 DHN , 31 dicoccoides 15 urartu 16 Aegilops tauschii were identified. The...
