A use of a ZmSBP12 gene in the regulation of drought resistance, plant height, and ear height ofL. is provided. After the ZmSBP12 gene is over-expressed inL., the resultingL. 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) ofL. The expression abundance of the ZmSBP12 gene is increased to improve the drought resistance ofL. and reduce the plant and ear heights ofL., which can be used for the assisted breeding of novel drought-resistant and lodging-resistantL. varieties and the breeding of excellent inbred lines and hybrids ofL.
