USE OF ZCN8 PROTEIN IN REGULATION OF PLANT RESISTANCE TO DROUGHT

Abstract

The present invention describes the use of the ZCN8 protein or the ZCN8 gene in regulating drought resistance in plants. Also described is a method for breeding drought-resistant plants, which includes increasing the content of the ZCN8 protein in the plant thereby increasing drought resistance. Further described is a method for creating transgenic plants with improved drought resistance, which includes introducing the ZCN8 gene or biological material related to the ZCN8 gene into a recipient plant to obtain a transgenic plant that has higher drought resistance than the recipient plant. The ZCN8 protein is the protein listed in SEQ ID NO: 1 of the sequence list. The ZCN8 gene is the gene that encodes the ZCN8 protein. Drought resistance is reflected in the fact that in a drought stress environment, the ASI (Average System Index) of the transgenic plant is lower than that of the original plant.Drought resistance is reflected in the fact that in drought-stressed environments, the yields of transgenic plants are higher than those of the original plants. Furthermore, transgenic plants containing the ZCN8 protein or the ZCN8 gene are also available.
