Wheat receptor-kinase-like protein Stb6 controls gene-for-gene resistance to fungal pathogen Zymoseptoria tritici
In this collaborative study between DFW researchers at RRes and JIC, and those from INRA in France the first wheat gene conferring resistance to a devastating foliar disease of wheat known as Septoria tritici blotch (STB) has been isolated. Most resistance genes in wheat, other monocots and also dicots code for protein NB-LRR receptors located […]
Transfer of a starch phenotype from wild wheat to bread wheat by deletion of a locus controlling B-type starch granule content.
Our previous genetic analysis of a tetraploid wild wheat species, Aegilops peregrina, predicted that a single gene per haploid genome, Bgc-1, controls B-type starch granule content in the grain. To test whether bread wheat (Triticum aestivum L.) has orthologous Bgc-1 loci, we screened a population of γ-irradiated bread wheat cv. Paragon for deletions of the group 4 chromosomes spanning Bgc-1. Suitable […]
Assessment of iron bioavailability from different bread making processes using an in vitro intestinal cell model
Myo-inositol hexakisphosphate (IP6), is the main iron chelator in cereals and bread. The aim of this study was to investigate the effect of three commercial baking processes (sourdough, conventional yeast and Chorleywood Bread Making Process (CBP)) on the IP6 content of wholemeal bread, its impact on iron uptake in Caco-2 cells and the predicted bioavailability […]
Crop nutrient and especially nitrogen use efficiency (NUE) is both an economically and an environmentally highly desirable trait. It has been estimated that only a third of nitrogen inputs to cereal crop worldwide are recovered in grain for consumption, resulting in a huge waste of resource with major negative impacts on the environment. Most measures […]
