This study validated one QTL for adult plant resistance to stripe rust, identified donor lines of the allele, and demonstrated that it is different from previously named Yr genes. The spread more virulent aggressive races Puccinia striiformis f. sp. tritici (Pst, causal pathogen rust) after year 2000 has caused substantial yield losses worldwide. To find new sources resistance, we performed a genome-wide association strong on short arm chromosome 6B (QYr.ucw-6B). In this study, QYr.ucw-6B in...
Abstract Wheat (Triticum aestivum L.) is one of the most important crops worldwide and a major source human cadmium (Cd) intake. Limiting grain Cd concentration (Gr_Cd_Conc) in wheat necessary to ensure food safety. However, genetic factors associated with uptake, translocation distribution Gr_Cd_Conc are poorly understood. Here, we mapped quantitative trait loci (QTLs) for its related transport pathway using recombinant inbred line (RIL) population derived from 2 Polish varieties (RIL_DT;...
Abstract Background The genus Pseudoroegneria (Nevski) Löve (Triticeae, Poaceae), whose genome symbol was designed as “St”, accounts for more than 60% of perennial Triticeae species. diploid species Psudoroegneria libanotica (2n = 14) contains the most ancient St genome, exhibited strong drought resistance, and morphologically covered by cuticular wax on aerial part. Therefore, St-genome sequencing data could provide fundamental information studies evolution reveal its mechanisms resistance....
ABSTRACT Disentangling the phylogenetic relationship of polyploid species is essential for understanding how such evolved following their origin. To investigate speciation and evolutionary history Eremopyrum , we analyzed 36 transcriptomes from 9 accessions 27 diploid taxa representing 12 basic genomes in Triticeae. Phylogenetic reconstruction, divergence time, introgression event demonstrated that (1) Agropyron shared a common ancestor; (2) has undergone ongoing diversification since its...
Non-glaucous wheat can reduce solar light reflection in low-light cultivation regions, enhancing photosynthetic efficiency and potentially increasing yield. In previous work, a non-glaucous cuticular line, YL-429, was discovered derivatives of pentaploid hybrids by crossing the synthetic LM/AT23 (non-glaucous cuticular) with its tetraploid donor parent LM (glaucous) selfing to F7 generations. present study, multicolor fluorescence situ hybridization used characterize karyotype YL-429 line;...
Fusarium head blight (FHB) is one of the major wheat diseases caused by species (mainly graminearum and asiaticum), resulting in significant global yield losses risks to food security. Breeding varieties with resistance genes most environmentally friendly economical strategy for controlling FHB. Psathyrostachys huashanica Keng ex P. C. Kuo (2n = 2x 14, NsNs), which showed abiotic tolerance biotic resistance, has research value potential as an important genetic resource improvement. In...
Wheat stripe rust is a destructive disease in the cool and humid wheat-growing areas of world. Finding diverse sources resistance critical for increasing genetic diversity wheat breeding programs. Stripe was identified alien species Psathyrostachys huashanica, wheat- P. huashanica amphiploid line (PHW-SA) with reported previously. In this study, 3Ns monosomic addition (PW11) superior to developed, which derived from cross between PHW-SA J-11. We evaluated introgressions PW11-2, PW11-5 PW11-8...
Encoding a glutathione S-transferase (GST) and conferring resistance to Fusarium head blight (FHB), Fhb7 was successfully isolated from the newly assembled Thinopyrum elongatum genome by researchers, with blasting searches revealing that gained through horizontal gene transfer an endophytic Epichloë species. On contrary, our molecular evidence reveals homologs of are distributed commonly in Triticeae. Other than Thinopyrum, were also detected four other genera, Elymus, Leymus, Roegneria...
The broad host range fungal insect pathogen, Beauveria bassiana, has been commercialized as an alternative to chemical insecticides for pest control worldwide. B. bassiana represents a unique model system with which examine host-pathogen interactions, and wide of genes processes have studied. However, significant aspects virulence, particularly on the genomic scale, remain poorly Here, we combined available transcriptomes three newly generated data sets total analysis 76 deep-sequenced...
The wheat dwarfing gene increases lodging resistance, the grain number per spike and harvest index. Dwarf Polish (Triticum polonicum L., 2n = 4x 28, AABB, DPW), initially collected from Tulufan, Xinjiang, China, carries a semi-dwarfing Rht-dp on chromosome 4BS. However, its mechanism are unknown.Homologous cloning mapping revealed that is 'Green Revolution' Rht-B1b. A haplotype analysis in 59 tetraploid accessions showed Rht-B1b was only present T. polonicum. Transcriptomic of two pairs...
Abstract Wide crosses and synthetic amphiploids have played an important role in introgressing desirable traits from related species into cultivated wheat. Hybrids between Triticum aestivum cv. ‘J‐11’ Psathyrostachys huashanica were treated with colchicine, to produce a new intergeneric amphiploid (PHW‐SA). The morphological characteristics of PHW‐SA resembled the parent ‘J‐11’. plants purple internodes pubescence basal spikelet, inherited P. parent. Somatic chromosome numbers varied 2n = 51...
Fusarium head blight (FHB) caused by the fungus graminearum Schwabe and stripe rust Puccinia striiformis f. sp. tritici are devastating diseases that affect wheat production worldwide. The use of disease-resistant genes cultivars is most effective means reducing fungicide applications to combat these diseases. Elymus repens (2n = 6x 42, StStStStHH) a potentially useful germplasm FHB resistance for improvement.Here, we report development characterization two wheat-E. lines derived from...
Tetraploid Thinopyrum elongatum (2n = 4x 28) is a promising source of useful genes, including those related to adaptability and resistance diverse biotic (Fusarium head blight, rust, powdery mildew, yellow dwarf virus) abiotic (cold, drought, salt) stresses. However, gene transfer rates are low for this species relatively few species-specific molecular markers available.The wheat-tetraploid Th. line K17-841-1 derived from cross between hexaploid Trititrigia Sichuan wheat cultivars was...
L. japonicus, a model plant of legumes plants, is widely used in symbiotic nitrogen fixation. A large number studies on it have been published based the genetic, biochemical, structural studies. These results are secondhand reports that CaM key regulator during Rhizobial infection. In there multiple genes encoding several isoforms with only minor amino acid differences. Moreover, regulation mechanism this family proteins rhizobia infection still unclear. current study, CaMs and CMLs possess...
Amphidiploids generated by distant hybridization are commonly used as genetic bridge to transfer desirable genes from wild wheat species into cultivated wheat. This method is typically enhance the resistance of biotic or abiotic stresses, and increase crop yield quality. Tetraploid Thinopyrum elongatum exhibits strong adaptability, stripe rust Fusarium head blight, tolerance salt, drought, cold. In present study, we produced hybrid derivatives crossing backcrossing Triticum durum–Th. partial...
Psathyrostachys huashanica Keng (2n = 2x 14, NsNs), a distant wild relative of common wheat, possesses rich potentially valuable traits, such as disease resistance and more spikelets kernels per spike, that could be useful for wheat genetic improvement. Development – P. translocation lines will facilitate its practical utilization in breeding. In the present study, small segmental line, K-13-835-3, was isolated characterized from BC 1 F 5 population cross between amphiploid PHW-SA cultivar...
