This invention discloses a wheat blue-grain gene and its applications, belonging to the fields of plant molecular biology, biochemistry, genetics, and plant breeding. Using differential expression analysis between blue-grain and white-grain wheat, four genes controlling the blue-grain trait were identified: two MYB family transcription factors and two bHLH family transcription factors. Furthermore, plant recombinant expression vectors for these genes and a method for regulating anthocyanin synthesis in plants are provided. This has significant theoretical and practical implications for studying the aleurone layer pigment synthesis pathway in blue-grain wheat, its use as a screening marker in plant transformation processes, and improving the nutritional value of plants.

The application belongs to the field of wheat processing, and particularly relates to a preparation method of high-activity wheat aleuron layer. Firstly, the dense structure of the aleuron layer is destroyed by extrusion puffing to form a porous loose matrix. This process not only increases the contact area between microorganisms and substrates, and relieves the problem of low fermentation efficiency caused by dense matrix in single fermentation, but also passivates part of the enzyme system through high-temperature and high-pressure pretreatment, and reduces the loss of nutrients. Then, solid-state fermentation is carried out by using specific mixed bacteria powder. Through the complementary metabolic pathways between the strains, the residual anti-nutritional factors after extrusion are further degraded, and the bound antioxidant components are released, which breaks through the limitations of single modification technology. Compared with simple fermentation or single strain treatment, the composite treatment can significantly improve the modification effect and processing adaptability of the wheat aleuron layer through strain functional complementation and synergistic metabolism.

The invention relates to the technical field of food or medicine, and particularly provides a new application of a wheat aleurone layer in preparation of a product for preventing skin aging. Experimental evaluation of a D-galactose induced aged mouse on the wheat aleurone layer proves that the wheat aleurone layer can remarkably improve the damaged condition of a skin cuticle, remarkably increase the skin epidermis thickness, remarkably improve the damaged condition of a skin collagen structure and remarkably improve the skin collagen density. Therefore, the wheat aleurone layer can be applied to preparation of products for preventing skin aging.
