Abstract

The invention provides an application of a ZmPYL11 gene in improvement of drought resistance of plants, and finds that the ZmPYL11 gene can significantly improve the drought resistance of corn, and through overexpression of the ZmPYL11 gene in corn, a corn plant with higher drought resistance is successfully constructed, and the application of the ZmPYL11 gene in the corn is realized. The relative water content of the leaf of the constructed ZmPYL11 overexpression plant after drought treatment is higher than that of the wild type, the leaf stomata is more sensitive to the process of promoting stomata closing by abscisic acid (ABA) than the wild type, the water loss rate of the in-vitro leaf is reduced, the drought resistance is obviously enhanced, and the yield is increased. The gene has wide application potential and market value in the field of agricultural planting, especially in improving the drought resistance of plants and cultivating drought-resistant transgenic crops.
