The invention provides a purple sweet potato leaf extract-containing composition with the effects of preventing hair loss and strengthening hair and a preparation method thereof.The composition is prepared from, by weight, 100-120 parts of purple sweet potato leaves, 25-35 parts of hyacinth bean coats, 25-35 parts of pyrus bretschneideri peels, 25-35 parts of Chinese waxgourd peels, 8-12 parts of Wuzmann grass, 90-110 parts of sophora flowers, 25-35 parts of morinda citrifolia ferment, 25-35 parts of cactus powder and 8-12 parts of snake slough. 25-35 parts of Chinese arborvitae twig and leaf and 25-35 parts of mulberry leaf. According to the composition containing the purple sweet potato leaf extract, all the extracts are compounded, the formula is scientific and reasonable, synergistic effect is achieved, irritation is small, safety is high, in the using process, hair roots are nourished, effective components efficiently penetrate into hair follicles, the activity of cells around the hair follicles is activated, hair growth is effectively promoted, alopecia is prevented, and the effect is good. The effects of preventing hair loss and fixing hair are achieved. Meanwhile, the composition has an efficient inhibition effect on 5alpha-reductase and main microorganisms, and the probability of seborrheic alopecia is reduced. In addition, the shampoo also has multiple effects of soothing the scalp, improving the scalp environment and nourishing the hair.

The invention relates to the technical field of plant protection and agricultural biology, in particular to a pear anthracnose resistance gene PbrLRP1 as well as an encoding protein and application thereof. According to the invention, the pear anthracnose resistance gene PbrLRP1 and the encoding protein thereof are found through mining, and gene editing and protein delivery tests prove that the pear anthracnose resistance gene PbrLRP1 can influence the resistance of plants to colletotrichum and sclerotinia sclerotiorum, so that a foundation is laid for the reference of the gene and the related protein in the aspect of improving the disease resistance of the plants.

The application discloses a low-temperature response gene separated and cloned from Pyrus x bretschneider Rehd PbXBAT31 and application of the gene in reducing the cold resistance of plants, and the application is characterized in that the gene is introduced into Arabidopsis and Solanum melongena callus by constructing an overexpression vector and using a bacterium-mediated transformation technique, and an overexpression strain is obtained. PbXBAT31 Test results of the cold resistance function show that the cloned PbXBAT31 gene has a significant ability of negatively regulating the cold resistance of plants.
