This invention discloses tree fern. AspiMYB5 The application of genes in regulating the biosynthesis of tree fern phenols belongs to the field of genetic engineering technology, which involves regulating the biosynthesis of tree fern phenols within plants. AspiMYB5 The expression level of the gene, thereby regulating the key enzyme gene of tree fern phenol. AspiPKS6 The expression of [a specific enzyme] and the synthesis of tree fern phenol. This invention uses a yeast library screening method to screen genes affecting key enzymes. AspiPKS6 Expressed transcription factors AspiMYB5 The results were verified using yeast single-hybrid technology (Y1H) and electrophoretic mobility variation analysis (EMSA). AspiMYB5 and AspiPKS6 The promoter exhibits direct physical binding in vitro. Dual-luciferase reporter gene assays further demonstrate that... AspiMYB5 and AspiPKS6 When the promoter is co-expressed, the fluorescence signal intensity is significantly reduced, further confirming... AspiMYB5 It can inhibit AspiPKS6 AspiMYB5 Promoter activity. This invention not only improves the theoretical research on the biosynthetic pathway of tree fern phenols, but also provides key target genes and technical support for regulating the content of secondary metabolites in rare plants through genetic improvement.

The application belongs to the technical field of cosmetics, and discloses a fucoidan composition, a preparation method and application thereof. The fucoidan composition comprises adiantum capillus-veneris fucoidan, ralfsia dactylifera fucoidan and pseudochoricystis sp. fucoidan, and the mass ratio of the adiantum capillus-veneris fucoidan, the ralfsia dactylifera fucoidan and the pseudochoricystis sp. fucoidan is (1-2):(1-2):(1-2). The fucoidan composition is prepared by compounding specific adiantum capillus-veneris fucoidan, ralfsia dactylifera fucoidan and pseudochoricystis sp. fucoidan, and has excellent whitening, anti-wrinkle, moisturizing and antioxidant multiple effects through synergistic effect. When the fucoidan composition is applied to cosmetics, it has good formula adaptability, does not affect the exertion of the effects and the stability of the cosmetics.
