To establish a transient gene expression system for investigating the molecular function of genes in mature wheat seeds, we bombarded embryos or aleurones of three hexaploid wheat (Triticum aestivum L.) varieties Chinese Spring, RL4137 and OS21-5, two diploid wheat (T. monococcum L.) varieties KT3-1 and KT3-5 and a barley (Hordeum vulgare, L.) variety Himalaya with fusion constructs containing ...
Pre-harvest sprouting (PHS) is an important cause of quality loss in many cereal crops and is particularly prevalent and damaging in wheat. Resistance to PHS is therefore a valuable target trait in many breeding programs. The Phs-A1 locus on wheat chromosome arm 4AL has been consistently shown to account for a significant proportion of natural variation to PHS in diverse mapping populations. Ho...
Phenolic compounds (PCs) affect the bread quality and can also affect the other types of end-use food products such as chapatti (unleavened flat bread), now globally recognized wheat-based food product. The detailed analysis of PCs and their biosynthesis genes in diverse bread wheat (Triticum aestivum) varieties differing for chapatti quality have not been studied. In this study, the identifica...
Comparisons between cereal species have shown that wheat starch is fermented more rapidly in the rumen than starch from maize, barley, potato or sorghum, probably due to the protein matrix surrounding the starch granules, but there are few comparisons of starch digestion from different cultivars of wheat. Although wheat varieties are classi®ed as being hard or soft, genetic factors affecting nu...
Let X/K be an absolutely simple abelian variety over a number field; we study whether the reductions Xp tend to be simple, too. We show that if End(X) is a definite quaternion algebra, then the reduction Xp is geometrically isogenous to the self-product of an absolutely simple abelian variety for p in a set of positive density, while if X is of Mumford type, then Xp is simple for almost all p. ...
Mineral concentrations in cereals are important for human health, especially for people who depend mainly on consuming cereal diet. In this study, we carried out a genome-wide association study (GWAS) of calcium concentrations in wheat (Triticum aestivum L.) grains using a European wheat diversity panel of 353 varieties [339 winter wheat (WW) plus 14 of spring wheat (SW)] and phenotypic data ba...
Carotenoid content is a primary determinant of wheat nutritional value and affects its end-use quality. Wheat grains contain very low carotenoid levels and trace amounts of provitamin A content. In order to enrich the carotenoid content in wheat grains, the bacterial phytoene synthase gene (CrtB) and carotene desaturase gene (CrtI) were transformed into the common wheat cultivar Bobwhite. Expre...
Plant ecology theory predicts that growing seed mixtures of varieties (variety mixtures) may increase grain yields compared to the average of component varieties in pure stands. Published results from field trials of cereal variety mixtures demonstrate, however, both positive and negative effects on grain yield. To investigate the prevalence and preconditions for positive mixing effects, report...
Fusarium head blight (FHB) is an important disease of wheat and production mycotoxins makes it a major threat in most wheat-producing areas worldwide. This study aimed to identify the impact epidemic FHB conditions (usage artificial inoculation) on mycotoxin levels unprocessed wheat. were monitored at two locations treatments (natural infection inoculation with graminearum F. culmorum) where 13...
