Gene Information

Bread-making quality is a crucial trait for wheat and triticale breeding. Several genes significantly influence these characteristics, including glutenin genes and the wheat bread-making (wbm) gene. World wheat collection screening showed that only a few percent of cultivars carry the valuable wbm variant, providing a useful source for wheat breeding. In contrast, no such analysis has been performed for triticale (wheat (AABB genome) × rye (RR) amphidiploid) collections. Despite the importance of the wbm gene, information about its origin and genomic organization is lacking. Here, using modern genomic resources available for wheat and its relatives, as well as PCR screening, we aimed to examine the evolution of the wbm gene and its appearance in the triticale genotype collection. Bioinformatics analysis revealed that the wheat Chinese Spring genome does not have the wbm gene but instead possesses the orthologous gene, called wbm-like located on chromosome 7A. The analysis of upstream and downstream regions revealed the insertion of LINE1 (Long Interspersed Nuclear Elements) retrotransposons and Mutator DNA transposon in close vicinity to wbm-like. Comparative analysis of the wbm-like region in wheat genotypes and closely related species showed low similarity between the wbm locus and other sequences, suggesting that wbm originated via introgression from unknown species. PCR markers were developed to distinguish wbm and wbm-like sequences, and triticale collection was screened resulting in the detection of three genotypes carrying wbm-specific introgression, providing a useful source for triticale breeding programs.

Trait Locus

Wheat bread-making quality is influenced by a complex group of traits including dough visco-elastic characteristics. In this study, quantitative trait locus/loci (QTL) mapping and analysis were conducted for endosperm polymeric proteins together with dough mixing strength and bread-making properties in a population of 139 (MN98550 × MN99394) recombinant inbred lines that was evaluated at three environments in 2006. Eleven chromosome regions were associated with endosperm polymeric proteins, explaining 4.2–31.8% of the phenotypic variation. Most of these polymeric proteins QTL coincided with several QTL for dough-mixing strength and bread-making properties. Major QTL clusters were associated with the low-molecular weight glutenin gene Glu-A3, the two high-molecular weight glutenin genes Glu-B1 and Glu-D1, and two regions on chromosome 6D. Alleles at these QTL clusters have previously been proven useful for wheat quality except one of the 6D QTL clusters.

SummaryTwenty-five winter wheat varieties and breeders' lines including hard and soft texture, good or poor bread and biscuit-making types were grown at two locations in the U.K. in 1977 to provide the test samples. Small-scale tests of bread-making quality including extensometer, sodium dodecyl sulphate (SDS) sedimentation volume, residue protein, urea dispersible protein and Pelshenke tests, were compared with loaf volumes and loaf scores.Averaged over the two sites, a modified extensometer test and the SDS test gave the closest correlation with loaf volume and loaf score and were only poorly correlated with Hagberg Falling Number and percentage protein. The SDS test gave the closest correlation between sites followed by the extensometer readings; loaf volume and score had much lower values. The SDS values and extensometer readings give a better measure of the genetic differences in protein quality of varieties than loaf volume and score, being less affected by growing conditions. With its small sample size and high throughput, the SDS sedimentation volume is likely to be the most useful screening test for wheat breeding programmes.

The aim of this investigation was to incorporate mustard flour into bread in order to improve its quality. For this purpose, wheat flour 650 type for bread making was replaced with mustard seed flour at the level of 5, 7 and 10%. Bread quality through physico-chemical and sensory characteristics was analyzed and compared to those of bread without mustard flour. The protein content of mustard flour bread increased with 5.03% as a result of mustard flour incorporation, coupled with an increase in ash content. Sensory evaluation results revealed that the sample containing 7% mustard flour scored highest in most of the attributes including overall acceptability. The study reveals that incorporation of 7% mustard flour gave desirable results in terms of phisyco-chemical and sensory caracteristics of mustard flour fortified bread.

The aim of this work was to compare the nutritional characteristics of wheat bread with the bread produced of wheat flour supplemented with quinoa and buckwheat seeds. Bread making properties of these blends were analyzed in order to investigate their ability to make moulded bread. Quinoa (Chenopodium quinoa Will.) and buckwheat seeds were grown in the vicinity of Belgrade, Serbia. The addition of pseudocereal seeds (at levels of 30% and 40%) and a selected technological process, which included hydrothermal preparation of supplements, resulted with a valuable effect on nutritive value of breads. In comparison with the wheat bread that was used as control sample, the protein increase of 2% and the increase of crude fiber content at around 0.5% in 30% supplemented breads were registered. Furthermore, the incorporation of both seeds mixture at the level of 40%, increased the content of protein for 2.5% and fiber content for 0.4%. In regard to the starch, fat, and ash contents there were no major differences. The investigated breads were nutritionally superior to the wheat bread. Chemical composition of the selected seeds was also investigated. The results showed that the blends containing either 30% or 40% of selected seeds expressed high potential for the production of molded breads, as new baking products with enhanced nutritional composition. The applied technological procedure was modified in such way that for all blended combination of supplements it changed rheological properties of dough. Furthermore, it resulted in a good volume of breads with excellent sensory properties of aroma-odor and taste.

The relation between high-molecular-weight (HMW) glutenin subunits and bread-making quality could enable selection for improved bread-making quality in early stages of breeding process. The composition of HMW glutenin subunits was investigated in F<sub>2</sub> and F<sub>7</sub> progenies derived from the cross between winter wheat varieties Sulamit and Clever. The presence of Glu-A1 (AxNull and Ax1), Glu-B1 (Bx6+By8 and Bx 17+By18) and Glu-D1 alleles (x 5+Dy10 and Dx 2+Dy12) was monitored using a PCR based assay. Segregation of alleles corresponded with the theoretically assumed 1:2:1 Mendelian ratio in F<sub>2</sub> generation, however, the values of &chi;<sup>2</sup>-test in F<sub>7</sub> generation indicated a strong affection of allelic frequencies by the breeding process. Significant variation was also observed in Glu-1 score frequency between F<sub>2</sub> and F<sub>7</sub> generation. These changes were probably caused by deliberate phenotypic selection for important agronomical traits. SDS and Zeleny sedimentation tests, mixographic parameter breakdown and HMW glutenin composition were analyzed in F<sub>7</sub> to reveal the effects of different combinations of HMW glutenin alleles on the bread-making quality characters. The results showed statistically significant differences in the contribution of HMW glutenin alleles. In general, the alleles Ax1, Bx17+By18 and Dx5+Dy 10 can be considered as markers of good baking quality. The data presented in this paper suggest that heterozygous constitution may also have a positive effect on bread-making quality.

AbstractThe effect of brewers’ spent grain addition on the thermo-mechanical properties of white and wholemeal wheat flour was investigated. The possibility to improve bread quality and antioxidant properties by using the sourdough fermentation was also considered. Increasing the level of brewers’ spent grain caused the increase of water absorption from 58.1 to 65.2% and from 63.8 to 73.6% in case of white and wholemeal flour, respectively. Similarly, the dough development time increased from 1.27 to 6.18 min, and from 3.37 to 5.42 min. Starch gelatinization significantly increased (p<0.05), while the stability of starch gel, starch retrogradation, and cooking setback significantly decreased (p<0.05) with the level of brewers’ spent grain. The specific volume of the wheat bread significantly decreased (p<0.05) and crumb hardness increased (p<0.05) by incorporation of brewers’ spent grain. Sourdough addition improved bread characteristics and the total phenolic content and antioxidant activity of the bread with brewers’ spent grain.
