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.
