Abstract Aegilops tauschii , the diploid wild progenitor of D subgenome bread wheat, is a reservoir genetic diversity for improving wheat performance and environmental resilience. Here we sequenced 242 Ae. accessions compared them to characterize genomic diversity. We found that rare lineage geographically restricted present-day Georgia contributed in independent hybridizations gave rise modern wheat. Through k -mer-based association mapping, identified discrete regions with candidate genes...
The ultrafiltration function of the glomerular basement membrane (GBM) kidney is impaired in genetic and acquired diseases that affect type IV collagen. GBM composed five (α1 to α5) six chains collagen, organized into an α1·α2(IV) α3·α4·α5(IV) network. In Alport syndrome, mutations any genes encoding α3(IV), α4(IV), α5(IV) cause absence α3·α4·α5 network, which leads progressive renal failure. present study, molecular mechanism underlying network defect was explored by further...
Genebanks are valuable resources for crop improvement through the acquisition, ex-situ conservation and sharing of unique germplasm among plant breeders geneticists. With over seven million existing accessions increasing storage demands costs, genebanks need efficient characterization curation to make them more accessible usable reduce operating so that community can most effectively leverage this vast resource untapped novel genetic diversity. However, inconsistent documentation often...
Abstract The wheat wild relative Aegilops tauschii was previously used to transfer the Lr42 leaf rust resistance gene into bread wheat. confers at both seedling and adult stages, it is broadly effective against all races tested date. has been extensively in CIMMYT international breeding program with resulting cultivars deployed several countries. Here, using a bulked segregant RNA-Seq (BSR-Seq) mapping strategy, we identify three candidate genes for . Overexpression of nucleotide-binding...
Aegilops tauschii, the D-genome progenitor of Triticum aestivum, encompasses huge diversity for various traits potential economic importance such as yield, biotic and abiotic stress tolerance, quality nutrition. In present study, variation grain size in Ae. tauschii germplasm was studied its genetic basis dissected using genome wide association study (GWAS). Grain length, width weight evaluated 177 accessions over three years showed near normal distribution with 1.74, 1.75 2.82-fold...
Aegilops tauschii, the D-genome donor of bread wheat, Triticum aestivum, is a storehouse genetic diversity, and an important resource for future wheat improvement. Genomic population analysis 549 Ae. tauschii 103 accessions was performed by using 13,135 high quality SNPs. Population structure, principal component, cluster confirmed differentiation into two lineages; lineage 1 (L1) 2 (L2), latter being donor. Lineage L1 contributes only 2.7% total introgression from set U.S. winter lines,...
Summary Next‐generation sequencing ( NGS ) provides a powerful tool for the discovery of important genes and alleles in crop plants their wild relatives. Despite great advances technologies, whole‐genome shotgun is cost‐prohibitive species with complex genomes. An attractive option to reduce genome complexity single chromosome prior sequencing. This work describes strategy studying genomes distant relatives wheat by isolating chromosomes from addition or substitution lines, followed sorting...
A-genome diploid wheats represent the earliest domesticated and cultivated wheat species in Fertile Crescent include donor of A sub-genome. The encompass einkorn (Triticum monococcum L. subsp. monococcum), wild (T. aegilopoides (Link) Thell.), Triticum urartu. We evaluated collection 930 accessions Wheat Genetics Resource Center (WGRC) using genotyping by sequencing identified 13,860 curated single-nucleotide polymorphisms. Genomic analysis detected misclassified genetically identical (>99%)...

Iris yellow spot is an economically important disease of onion that reduces bulb size and yield difficult to control. The spread by Thrips tabaci (onion thrips) symptoms are exacerbated hot, dry climatic conditions also favor rapid thrips multiplication make control programs less effective. Currently, no cultivar resistant the and/or thrips. Certain foliar characteristics have shown nonpreferential feeding activity may be first step in developing (IYS)-tolerant cultivars. Seventy-five PI...
Abstract Aegilops tauschii, the diploid wild progenitor of D-subgenome bread wheat, constitutes a reservoir genetic diversity for improving wheat performance and environmental resilience. To better define understand this diversity, we sequenced 242 Ae. tauschii accessions compared them to D-subgenome. We characterized rare, geographically-restricted lineage discovered that it contributed D-subgenome, thereby elucidating origin from at least two independent hybridizations. then used k...
Iris yellow spot (IYS) disease, caused by virus (IYSV), results in irregular and diamond-shaped, chlorotic, necrotic lesions on the leaves seedstalks of onions ( Allium cepa L.). These reduce leaf photosynthetic area ultimately onion bulb size yield from larger classes. IYSV is vectored thrips Thrips tabaci L.) that are difficult to control under certain environmental conditions. Currently, no cultivar resistant disease symptoms, virus, and/or thrips. Twenty-one cultivars 17 germplasm lines...
Iris yellow spot (IYS), a disease caused by virus (IYSV) and spread onion thrips, is devastating of bulb seed production. The development germplasm resistant to IYS and/or thrips crucial production, since host plant resistance unknown for both pests. During the summer 2010 2012, plants with fewer symptoms were selected from screening introduction accessions (PIs) first-generation selections, respectively. resulting progeny these evaluated during summers 2013 2014 numbers symptom expression,...

The usefulness of the indicator dye method for detection transient enzyme-product intermediates has been very limited due to near impossibility resolving apparent single exponential time courses resulting from sequences steps linked by rather similar rate constants. We propose here a novel approach, proton-product course method, procedure which can extract great deal mechanistic information remains buried in conventional proton release-time measurements. involves nothing more than measuring...
