The invention relates to the technical field of rice high-yield cultivation, and discloses a northern rice high-yield population construction and cultivation method based on light and temperature close planting regulation, comprising the following steps: S1, light, temperature and regional environment monitoring: collecting illumination and temperature data and soil and irrigation and drainage conditions of a northern rice planting region, and establishing a regional light and temperature change model; s2, variety matching and sowing period determination: combining the light and temperature sensitive characteristics of the rice variety with the monitoring data in the step S1. According to the method, on the basis of real-time light and temperature monitoring and a over-the-year big data model, the key growth period and the high light and temperature period of rice are accurately aligned, the advantages of sufficient illumination and large day and night temperature difference of northern rice areas are utilized to the maximum extent, and water, fertilizer and field management are adjusted by dynamically adapting to light and temperature changes; and for example, nutrient supply is optimized when illumination is insufficient, and cooling measures are taken at high temperature, so that the accumulation and transfer efficiency of photosynthetic products is remarkably improved, the problem of insufficient utilization of light and temperature resources in traditional cultivation is solved, and a material foundation is laid for high yield.

The invention provides an application of an StMYB113b gene in regulating and controlling the epidermal color of a potato tuber. According to the invention, the key gene StMYB113b for regulating and controlling the formation of the red skin pigment of the potato tuber is found and cloned for the first time, and the gene can influence the skin color of the potato tuber by regulating and controlling the synthesis of an anthocyanin-related compound. Through overexpression or knockout of the gene, regulation and control of the potato tuber epidermis color can be achieved, a new way and gene resources are provided for potato variety improvement, and the gene has important theoretical value and application prospects.

The present invention provides "a conjugate of a chelating agent chelated with a radionuclide and a deglycosylated antibody, wherein the chelating agent site-specifically modifies the Fc region of the aforementioned antibody via a linker". The conjugate is improved in the risk of a decrease in the effect and the risk of side effects.

The application provides a preparation method of an aggregation-induced emission nanoparticle, which comprises the following steps: adopting triphenylamine as an electron donor (D), pyridine bromide as an electron acceptor (A), constructing a D-π-A structure, and synthesizing a nanoscale AIE photosensitizer nanoparticle by acting with an albumin stock solution; the nanoparticle synthesis method is easy to operate, has high yield and low cost, can simultaneously generate type I and type II reactive oxygen species (ROS), including ·OH (type I) and O2 (type II), and has good mitochondrial targeting function, and a Pearson correlation coefficient is as high as 0.97. 1 In addition, due to the modification of the terminal carboxyl group of TTPA, the nanoparticle has a pH response effect, can increase the accumulation or endocytosis of the nanoparticle in tumors, and can enhance the in-vivo imaging and treatment effect, and has potential clinical application value of intelligent response cancer diagnosis and treatment function.
