  • Patent number: 11879131
    Abstract: A use of a ZmSBP12 gene in the regulation of drought resistance, plant height, and ear height of Zea mays L. is provided. After the ZmSBP12 gene is over-expressed in Zea mays L., the resulting Zea mays L. mutant plant exhibits increased drought resistance and decreased plant and ear heights. The overexpression of the ZmSBP12 gene leads to increased drought resistance and decreased plant and ear heights, indicating that the ZmSBP12 gene plays a crucial role in the drought resistance and plant type (plant height) of Zea mays L. The expression abundance of the ZmSBP12 gene is increased to improve the drought resistance of Zea mays L. and reduce the plant and ear heights of Zea mays L., which can be used for the assisted breeding of novel drought-resistant and lodging-resistant Zea mays L. varieties and the breeding of excellent inbred lines and hybrids of Zea mays L.

  • Patent number: 11348275
    Abstract: Embodiments of the present application disclose methods and apparatuses for determining a bounding box of a target object, media, and devices. The method includes: obtaining attribute information of each of a plurality of key points of a target object; and determining a bounding box position of the target object according to the attribute information of each of the plurality of key points of the target object and to a preset neural network. The implementations of the present application can improve the efficiency and accuracy of determining a bounding box of a target object.
