Problems solved by technology

[0007] Although so far, the research on the loci of high molecular weight and low molecular weight glutenin and its influence on wheat quality has made great progress, compared with glutenin, due to the complexity and difficulty of research, except for some allergic reactions and Beyond basic properties, research on gliadins has been limited to

Embodiment 1

[0059] Embodiment 1: the development of new wheat variety

[0060] A new wheat variety with high cold tolerance and ideal growth habit was developed by artificial crossing Keumkang and Olgeuru to obtain the offspring wheat plant F1. F1 haploids were bred at CIMMYT in Mexico and F1 production was tested in Iksan for four years. The new wheat variety was named "Ofree" ( figure 1 ).

Embodiment 2

[0062] Example 2: Genotype identification of Offree

Embodiment 2-1

[0063] Example 2-1: Confirmation of deletion of a gene located at the Glu-B3 locus

[0064] The genetic characterization of Offree developed by the procedure described in Example 1 is based on the genes located at the Glu-1 locus as components of the high molecular weight glutenin subunits (HMW-GSs) in gluten and those located at the Glu-3 locus. Expression levels of genes that are components of the low molecular weight glutenin subunits (LMW-GSs) in gluten were determined.

[0065] Briefly, genomic DNA was extracted from young leaves of Keumkang, Olgeuru and Ofree using the Genomic DNA Extraction Kit for Plants (SolGent Co., Ltd., Korea). Subsequently, polymerization was performed using the genomic DNA extracted earlier as a template and primers capable of detecting genes located at the Glu-A1, Glu-B1, Glu-D1, Glu-A3, Glu-B3, or Glu-D3 loci (listed below) Enzyme chain reaction (PCR) to determine which genes located in the Glu-1 and Glu-3 loci are included in Ofree's geneti...

Abstract

The present invention relates to Offree, a novel wheat variety produced by crossing Keumkang wheat and Olgeuru wheat, in which the low molecular weight glutenin subunit (LMW-GS) allele at the Glu-B3 locus (gluten-intolerant major cause) and the omega‑5 gliadin gene (the major cause of wheat-dependent‑exercise-induced anaphylaxis (WDEIA)) deleted; a method for developing new wheat varieties using Offree; wheat flour produced by Offree; a method using A method for producing a processed food from wheat flour; and a processed food produced by the above production method. Offree provided by the present invention is expected to be widely used in the production of processed foods capable of preventing the onset of celiac disease and WDEIA caused by gluten intolerance.

Description

technical field [0001] The present invention relates to a novel wheat variety and its application for improving or preventing gluten intolerance and wheat dependence-exercise-induced allergic reaction (WDEIA). Background technique [0002] Celiac disease is a disease caused by gluten intolerance, a digestive disorder characterized by difficulty digesting ingredients such as gluten found in wheat, barley, rye, and oats, and affecting the intestines between the digestive organs. . Unlike most people who have no problems digesting and absorbing gluten, people with gluten digestion problems experience an induced immune response in the gastrointestinal tract that causes inflammation of the mucosal cells of the digestive organs and destroys the villi. In this case, nutrients are not easily absorbed, and it causes various symptoms such as growth retardation, loss of appetite, chronic diarrhea, bloating, dermatitis herpetiformis, and anemia caused by iron deficiency, resulting in m...
