APPLICATION OF ZMSBP12 GENE IN REGULATION AND CONTROL OF DROUGHT RESISTANCE, PLANT HEIGHT AND EAR HEIGHT OF CORN

摘要

Provided is an application of the ZmSBP12 gene in the regulation and control of drought resistance, plant height and ear height of corn. After overexpressing the ZmSBP12 gene in corn, a corn mutant plant has characteristics such as increased drought resistance, reduced plant height and reduced ear height. Overexpression of ZmSBP12 leads to an increase in drought resistance and a reduction of plant height and ear height, indicating that the ZmSBP12 gene plays a vital role in characteristics such as drought resistance and plant type (plant height) corn. By increasing the expression abundance of the ZmSBP12 gene, the effects such as improving the drought resistance of the corn and reducing the plant height and ear height of the corn are achieved, and the gene may be applied to auxiliary breeding of new drought-resistant and lodging-resistant corn varieties and may also be applied to cultivation of excellent inbred lines and hybrids of the corn.
