8 results about "Rosaceae" patented technology

The application belongs to the technical field of plant genetic engineering, and discloses a functional gene PbCOB.A.1 and application thereof. The in-vitro expressed recombinant protein PbCOB.A.1 can promote pollen tube growth of Rosaceae fruit trees, improve pollination efficiency, and expand the regulation mechanism of non-S factors participating in self-incompatibility reaction in pears. The mechanism of pear pollen tube elongation is researched by using magnetic transfection technology, so that the labor cost can be greatly reduced, and a theoretical basis is provided for pear breeding work.

The invention relates to application of a group of InDel markers for efficiently identifying distant hybridization filial generations of apples and pears. The invention discloses a group of InDel markers for efficiently identifying distant hybridization filial generations of apples and pears. Wherein the InDel-1, the InDel-2, the InDel-3 and the InDel-4 are respectively positioned on a chromosome 3, a chromosome 2, a chromosome 6 and a chromosome 14 of an apple reference genome. Through the combined use, 100%, 80.4%, 72.4% and 82.5% of hybrids can be respectively identified in hybrid populations of 'Jinguan' * 'Zhuangzhuang', 'Jinguan' * 'Jinzhuang', 'Fuji' * 'Zhuangzhuang' and 'Fuji' * 'Jinzhuang'. Therefore, the InDel molecular marker disclosed by the invention can provide a rapid and accurate identification method for distant filial generations of apples and pears, and also provides an important tool for creating new varieties of rosaceae fruit trees.

WATER-SOLUBLE EXTRACT FROM A PLANT OF THE PRUNUS SPECIES TO PREVENT THE DELETE EFFECTS OF THE EXPOSOME. The present invention relates to the use of a flower extract from a plant of the Rosaceae family and the Prunus genus, or a composition thereof, to protect the skin from the deleterious effects of the exposome, including disruption of the barrier function, neurogenic inflammation, irritation, and oxidative stress. The invention is thus intended to prevent the clinical signs of premature aging, including the appearance of hyperpigmentation spots responsible for loss of skin tone uniformity and skin hyperreactivity.

This invention discloses a method for preparing biphenyl compounds from hawthorn leaves and their applications, belonging to the field of pharmaceutical technology. The biphenyl compounds from hawthorn leaves, as shown in the structural formula below, are obtained by separating the 70% ethanol extract from the dried leaves of hawthorn (Crataegus pinnatifida Bge.), a plant of the Rosaceae family, using various column chromatography and HPLC methods. DPPH free radical scavenging activity tests show that compounds 1 and 2 have good DPPH free radical scavenging activity, and their activity is stronger than that of the positive control drug VC. ABTS free radical scavenging activity tests show that compounds 1 and 2 have good ABTS free radical scavenging activity, and their activity is stronger than that of the positive control drug VC. Compounds 1 and 2 provided by this invention exhibit superior antioxidant activity; therefore, the biphenyl compounds described in this invention have the potential to be used in the preparation of clinical antioxidant drugs.

The invention discloses an IRAP marker primer developed based on a cherry genome, develops a specific IRAP marker primer based on an LTR-RT family of the cherry genome, establishes an efficient and stable detection system, not only can solve the technical bottleneck in current cherry germplasm identification and genetic analysis, but also can provide a new tool for cross-species research of rosaceae fruit trees, and has a wide application prospect. The method has important significance on sustainable development of the cherry industry.

This utility model relates to a quick connection device for single-screw extrusion injection molding of artificial flowers of the Rosaceae family. It includes a fastening mechanism fixed to the base of a mold, with an electromagnetic material A at one end of the fastening mechanism near the mold. A guide rod perpendicular to the mold is mounted on the fastening mechanism, and an injection head perpendicular to and adapted to the mold's feed inlet slides on the guide rod. The injection head is connected to the discharge port of the single-screw extruder via a conveying pipe. The injection head is connected to the fastening mechanism via a return spring, and an electromagnetic mechanism B is mounted on the injection head. This utility model uses the attraction between electromagnetic material A and electromagnetic mechanism B to drive the injection head toward the mold's feed inlet and press the injection head and mold together, thereby connecting the single-screw extruder and the mold cavity. The return spring drives the injection head to automatically detach from the mold, thus quickly connecting the single-screw extruder and the mold. This method is simple, efficient, safe, and reliable.
