Problems solved by technology

However, most of the molecular markers closely linked to these QTLs are non-gene-specific markers such as AFLP and SSR, which cannot be co-segregated with the target gene. At the same time, the application cost in molecular breeding is high, so they cannot be widely used in molecular assisted breeding.

Abstract

The invention discloses a wheat yellow pigment content associated protein and a coding gene and an application for the same. The wheat yellow pigment content associated protein is a yellow pigment content associated protein which has sequence 1 or 3 or 5 or 7 in a sequence list after undergoing replacement and / or loss and / or addition of one or a plurality of amino acid residues. The invention also provides the coding gene of the protein and a specificity functional mark based on wheat gene allelic variation. Through two times of genotyping, the mark can be used to judge the gene associated with the yellow pigment content in the wheat. The invention can be used to screen wheat breeds during the early development period, thereby optimizing hybrid combination, quickening breeding and reducing breeding cost. The method for detecting the wheat yellow pigment content and character has the advantages of simple operation, stability and reliability, low cost and short cycle. The method suitable for generalization has important theoretic significance and economic value concerning rapidly improving the color of wheat products.

Description

A wheat yellow pigment content trait-related protein, its coding gene and application technical field The invention relates to a wheat yellow pigment content trait-related protein, its coding gene and application. Background technique With the improvement of living standards, people have put forward higher requirements for the appearance quality of food while paying attention to the nutritional quality of food. my country's traditional foods such as noodles and steamed buns have higher requirements on color, and foods with white and bright colors are more popular with consumers (He et al., 2003; Yang Jin et al., 2004). In order to cater to consumers' desire for whiteness in flour products, some manufacturers add whitening agents to flour to improve the whiteness of flour. In recent years, the quality inspection report of the national quality inspection department on the flour industry shows that the content of whitening agents in most flours in my country seriously exceed...
