Abstract: A rice white leaf and panicle gene wlp3 is provided. The cDNA sequence of the white leaf and panicle gene wlp3 is shown in SEQ ID NO: 1, and the encoded amino acid sequence of the protein is shown in SEQ ID NO: 2. The rice white leaf and panicle gene wlp3 is applied to rice stress resistance and yield increase. The white leaf and panicle gene wlp3 is configured to improve cold tolerance of plants, enhance photosynthetic rate, increase plant height, leaf albinism at seedling stage, panicle albinism at heading stage, and increase panicle length at low temperature. The present disclosure obtains the rice white leaf and panicle gene wlp3 through screening and mutagenesis, which is related to the stress resistance and chlorophyll synthesis of rice. Therefore, the present disclosure provides a foundation for rice breeding.

Abstract: Provided are an organic light-emitting diode (OLED) lamp panel and a lighting device. A display region of the lamp panel includes at least one main display region and a display peripheral region. The main display region is regular in shape and is formed by splicing multiple main light-emitting units of the same shape. The display peripheral region consists of a peripheral region I and/or a peripheral region II. The peripheral region I is formed by multiple first peripheral light-emitting units with regular shapes. The display region of the OLED lamp panel is designed to include at least one main display region and a display peripheral region.

Abstract: A two-dimensional motor and a servo valve are provided. The two-dimensional motor includes a stator and a rotator arranged coaxially. The stator is enclosed in the rotor. The stator and the rotor are spaced along a radial direction of the rotor. A size of the stator along an axial direction is greater than a size of the rotor along the axial direction. The rotor is, without bearing support, directly connected to an external mechanism. The rotor is swung at a predetermined angle, such that the external mechanism can drive the rotor to move along an axial direction of the rotor relative to the stator.

Abstract: A method for breeding a new germplasm of clubroot-resistant orange-heading Chinese cabbage includes: (1) obtaining F1 by hybridizing orange-heading Chinese cabbage as a female parent and clubroot-resistant Chinese cabbage as a male parent, obtaining F2 by selfing F1 individual plants, planting F2 populations, and extracting DNA from the individual plants of F2; (2) observing horticultural traits of F2, and performing observation and statistics of head color phenotypic traits through cutting head; (3) performing PCR amplification with DNA of F2 using a dominant orange gene marker Br530 and a clubroot-resistant marker SC2930-T/SC2930Q, and identifying a genotype of the individual plants; (4) performing a comprehensive evaluation according to the results of marker detection and the observation of horticultural traits, selecting double-site homozygous clubroot-resistant orange-heading Chinese cabbage plants, and selfing the individual plants for 2 consecutive generations; and (5) obtaining a new germplasm of club

Abstract: A method for breeding new purple-orange Chinese cabbage germplasm crosses the purple head Chinese cabbage inbred line 11S96 as the male parent and the orange Chinese cabbage inbred line 11J11 as the female parent. On the basis of selecting individual plants with good heading property in the F2 population, molecular markers are used to select individual plants carrying the purple-head gene and the orange gene. Through selfing of individual plants for three consecutive generations, a new Chinese cabbage germplasm with green outer leaves and purple-orange head leaves is bred. This method aggregates the purple-head gene and orange gene which are expressed in the head leaves of Chinese cabbage, creating a new Chinese cabbage germplasm with purple-orange head leaves. It enriches Chinese cabbage breeding materials, lays the foundation for breeding the new purple-orange Chinese cabbage variety, and sets a precedent for the aggregation of the head color traits of Chinese cabbage.
