Researchers have created wheat that is resistant to a common disease, using advanced gene editing methods.
Scientists there have created a way to make wheat release a pheromone that mimics the pheromone of a frightened aphid (a type of pest), which then signals other aphids to flee.
Norman Borlaug, an American plant breeder, used a strain of Japanese semi-dwarf wheat, known as Norin 10, which had been bred in Japan and brought to the United States in 1946, during the Allied occupation, to create a wheat with a stalk short enough to support a larger, more productive head.
In the current study, an inventory of the abundance of adverse environmental conditions during critical growth stages was created for wheat and maize grown in four regions representing the North German Plain.
We estimate that most (at least 60%) homoeolocus loss events occurred after the two polyploidization events that created bread wheat.
Concatenating ESTs from chromosomes 1 (1,123) and 5 (1,247), we created a wheat group 1 and 5 partial reference transcriptome consisting of 2,354 ESTs (see Methods).
It is because, as I described earlier, the dwarf wheat grown in this country has changed the quality and type of gluten proteins in wheat, creating much higher gluten content and many more of the gluten proteins that cause celiac disease and autoimmune antibodies.
Seeking to assist impoverished farmers who struggled with diseased and low-producing crops, Borlaug experimented with novel varieties of wheat, creating disease-resistant strains that could withstand the harsh climate.
Borlaug also created a wheat-rye hybrid known as triticale, and his methods were used by others to develop new varieties of highly productive rice.
In order to gain a better understanding of the effects of allopolyploidization on the regulation of diverged gene networks, we performed a genome-wide analysis of homoeolog-specific gene expression in re-synthesized allohexaploid wheat created by the hybridization of a tetraploid derivative of hexaploid wheat with the diploid ancestor of the wheat D genome Ae. tauschii.
