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.
