Starch present in the endosperm of common wheat (Triticum aestivum L.) grains is an important source of carbohydrates worldwide. Starches with a greater proportion of amylose have increased levels of resistant starch, a dietary fiber that can provide human health benefits. Induced mutations in STARCH BRANCHING ENZYME II (SBEII) genes in wheat are associated with increased amylose and resistant ...
Spike density and processing quality are important traits in modern wheat production and are controlled by multiple gene loci. The associated genes have been intensively studied and new discoveries have been constantly reported during the past few decades. However, no gene playing a significant role in the development of these two traits has been identified. In the current study, a common wheat...
We developed oligo-DNA microarrays of common wheat. These microarrays were designed to include approximately 32,000 unique genes represented by a large number of expressed sequence tags (ESTs). In order to characterize the salt-responsive genes in common wheat, the expression profiles of transcripts that responded to salt-treatment were monitored using the microarrays. Two-week-old seedlings of...
Variations in the reverse transcriptase domain were analyzed to clarify the family structure of retrotransposons in the wheat genome. Seven families were identified on the basis of the nucleotide sequence similarities of the domain. These families are common to the genomes of ancestral diploid species of wheat, evidence that they were established prior to diploid speciation, and their presence ...
An Aegilops ventricosa Translocation Confers Resistance Against Root-knot Nematodes to Common Wheat.
Root knot nematodes (RKN; Meloidogyne spp.) cause severe losses worldwide to a wide range of crops. Crop rotations with resistant hosts can be used to control losses, but the wide host range of RKN limits this option. In this study, we found that the wheat cultivar Lassik is resistant to several isolates of the RKN species M. incognita and M. javanica, including those that can reproduce on toma...
Grain size and shape associated with yield and milling quality are important traits in wheat domestication and breeding. To reveal the genetic factors on the D genome that control grain size and shape variation, we conducted analysis of quantitative trait loci (QTL) using the F2 and F2:3 populations derived from a common allohexaploid wheat line TAA10 and a synthetic allohexaploid wheat XX329, ...
A novel Dasypyrum species, Dasypyrum breviaristatum, serves as a valuable source of useful genes for wheat improvement. The development and characterization of new wheat-D. breviaristatum introgression lines is important to determine the novel gene(s) on specific chromosome(s). We first used multi-color fluorescence in situ hybridization (FISH) to identify the individual D. breviaristatum V(b) ...
The article contains results of the flour and bread quality assessment from the grains of spring spelt, also called as an ancient wheat. Spelt was cultivated on heavy and medium soils observing principles of organic farming. Based on flour and bread laboratory studies, as well as laboratory baking, the technological usefulness of studied flour has been determined. These results were referred to...
Food dependent exercise induced anaphylaxis (FDEIA) is an IgE mediated adverse reaction to specific foods, where symptoms only appear in combination with physical activity. In absence of exercise, subjects with FDEIA tolerate the offending food. FDEIA can, as the nomenclature indicates, be life threatening, but most common symptoms are urticaria, flushing, pruritus and angioedema. The mechanism...
A tight link exists between dietary factors and irritable bowel syndrome (IBS), one of the most common functional syndromes, characterized by abdominal pain/discomfort, bloating and alternating bowel habits. Amongst the variety of foods potentially evoking "food sensitivity", gluten and other wheat proteins including amylase trypsin inhibitors represent the culprits that recently have drawn the...
