A diminutive rye chromosome (midget) in wheat was used as a model system to isolate highly reiterated centromeric sequence from chromosome. Fluorescence situ hybridization (FISH) shows this localized within all centromeres and no signal detected on chromosomes. DNA sequencing of the repetitive element has revealed presence some catalytic domains signature motifs typical retrotransposon genes been called Bilby family, representing diverged family retrotransposon-like elements. Extensive...
Summary Metabolomics is becoming an increasingly important tool in plant genomics to decipher the function of genes controlling biochemical pathways responsible for trait variation. Although theoretical models can integrate and metabolites variation, biological networks require validation using appropriate experimental genetic systems. In this study, we applied untargeted metabolite analysis mature grain wheat homoeologous group 3 ditelosomic lines, selected compounds that showed significant...
Lophopyrum elongatum, a close relative of wheat, provides source novel genes for wheat improvement. Molecular markers were developed to monitor the introgression L. elongatum chromosome segments into hexaploid wheat. Existing simple sequence repeats (SSRs) derived from genomic libraries initially screened detecting loci in but only 6 163 tested successful. To increase detection specific loci, 165 SSRs identified expressed tags (ESTs), where their chromosomal positions known deletion bin...
Stagonospora nodorum blotch (SNB) caused by is a severe disease of wheat (Triticum aestivum) in many areas the world. S. affects both seedling and adult plants causing necrosis leaf glume tissue, inhibiting photosynthetic capabilities, reducing grain yield. The aims this study were to evaluate response 280 doubled haploid (DH) individuals derived from cross between resistant (6HRWSN125) susceptible (WAWHT2074) genotypes, compare quantitative trait loci (QTL) for plant resistance two...
Chromosome 1R of rye is a useful source genes for disease resistance and enhanced agronomic performance in wheat. One the most prevalent transferred to wheat from stem rust gene Sr31. The recent emergence spread pathotype virulent this has refocused efforts find utilize alternative sources resistance. There been considerable effort transfer gene, SrR, Imperial rye, believed be allelic Sr31, into commercial cultivars. However, simultaneous at Sec-1 locus encoding secalin seed storage proteins...
The slow rate of genetic gain for improving resistance to Septoria nodorum blotch (SNB) is due the inherent complex interactions between host, isolates and environments. Breeding improved SNB requires evaluation selection wheat genotypes consistently expressing low response in different target production study focused on evaluating 234 from global origins flag leaf expressed Western Australian aim was identify resistant donor germplasm against historical contemporary pathogen enhance our...
Stagonospora nodorum blotch (SNB) is a significant disease in some wheat-growing regions of the world. Resistance wheat to complex, whereby genes for seedling, flag leaf, and glume resistance are independent. The aims this study were identify alternative leaf resistance, compare contrast with known quantitative trait loci (QTL) SNB determine potential role host-specific toxins QTL. Novel QTL identified on chromosome 2AS inherited from winter parent ‘P92201D5’ 1BS spring ‘EGA Blanco’....
Resistance to stagonospora nodorum blotch (SNB) in glumes of hexaploid wheat ( Triticum aestivum L.), caused by Phaeosphaeria Stagonospora anamorph) was investigated a recombinant‐inbred (RI) population. The Purdue University winter breeding lines P91193D1 and P92201D5, unrelated parentage but both exhibiting partial SNB resistance, were crossed develop 254 RI single‐seed descent (SSD) from random population F 2 plants, identify quantitative trait loci (QTLs) controlling resistance glumes....
The genetic control of adult plant resistance to Stagonospora nodorum blotch (SNB) is complex, consisting genes with minor effects interacting in an additive manner. Earlier studies detected quantitative trait loci (QTL) for flag leaf successive years on chromosomes 1B, 2A, 2D, and 5B using SSR- DArT-based maps progeny from the crosses EGA Blanco/Millewa, 6HRWSN125/WAWHT2074, P92201D5/P91193D1. Similarly, QTL glume multiple environments were identified 2D 4B P92201D5/P91193D1 respectively....
Abstract Matrix‐assisted laser desorption/ionization time‐of‐flight (MALDI‐TOF) instrumentation has been used to analyze wheat seed gliadins as an alternative other established methods, including sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS‐PAGE), capillary (CE), high‐performance liquid chromatography (HPLC), etc. The MALDI‐TOF approach shown have many advantages such high resolution, cost effectiveness and throughput. MALDI‐TOF‐based gliadin profiles for fast cultivar...
