Medicago sativa MsPUB3.4 III-439 The application of genes in improving plant stress resistance belongs to the technical field of genetic engineering and crop genetic breeding technology. In order to solve the technical problems that there is currently a lack of available alfalfa stress resistance gene resources, and especially the function of PUB family members in abiotic stress and the technical solutions thereof are still blank, experiments prove that, under the conditions of salt stress and / or low temperature stress, the transgenic plants overexpressing the alfalfa MsPUB3.4 III-439 gene exhibit significantly enhanced stress tolerance compared with wild type control plants, indicating that the alfalfa MsPUB3.4 III-439 gene can effectively improve the adaptability of plants to abiotic stress. The present application provides a new gene resource for plant stress resistance breeding, and has important significance for the study of stress resistance improvement and plant growth and development regulation mechanism.

The invention relates to the technical field of medical drug preparation, in particular to a total glucosides of paeony nano preparation for treating inflammatory diseases and a preparation method of the total glucosides of paeony nano preparation. The nanogel dispersoid is formed by self-assembling molecules in a water phase through thermal induction gelatinization and a subsequent cooling process; the mass ratio of the total glucosides of paeony to the starch is (1: 10)-(1: 50); the average hydrated particle size of gel particles in the nanogel dispersion ranges from 80 nanometers to 300 nanometers, and the polydispersity index of the gel particles is smaller than 0.3. According to the total glucosides of paeony nano preparation for treating inflammatory diseases and the preparation method thereof, the process is simple, the cost is low, complicated equipment or organic solvents are not needed, the preparation is very suitable for industrial production, edible starch is taken as a carrier material, the biocompatibility is excellent, the safety is high, the enrichment of medicines at inflammatory parts can be effectively improved, the action time can be prolonged, and the application prospect is wide. Therefore, curative effect is improved, and administration frequency is reduced.

The application belongs to the technical field of biology, and discloses a Undaria pinnatifida sporophyll-derived active peptide as well as a preparation method and application thereof. The Undaria pinnatifida sporophyll-derived active peptide is selected from at least one of peptides with amino acid sequences as shown in SEQ. ID. NO. 1-4. The Undaria pinnatifida sporophyll-derived active peptide is obtained by screening from Undaria pinnatifida sporophyll through bioinformatics tools and molecular docking. Experiments prove that the Undaria pinnatifida sporophyll-derived active peptide has antioxidant and anti-inflammatory activities, and can be used for preparing antioxidant or antioxidant-assisted products and anti-inflammatory products.
