METHOD FOR IMPROVING SENSITIVITY OF PLANT TO GIBBERELLIN INHIBITOR AND USE THEREOF

摘要

Disclosed are a method for improving the sensitivity of a plant to a gibberellin inhibitor and the use thereof. The method provided in the present invention for improving the sensitivity of a plant to a gibberellin inhibitor comprises the step of: introducing the encoding gene of a protein into a recipient plant to obtain a transgenic plant, wherein the sensitivity of the transgenic plant to the gibberellin inhibitor is increased compared to the recipient plant, and the protein is the following protein of a) or b) or c): a) a protein with an amino acid sequence being amino acids at sites 1-821 in sequence 1; b) a protein with an amino acid sequence being sequence 1; and c) a fused protein formed by linking a tag to the N-terminal and/or C-terminal of protein a) or protein b). Experiments prove that the method of the present invention for improving the sensitivity of a plant to a gibberellin inhibitor can be used to improve the sensitivity of a plant to a gibberellin inhibitor, and the height of the plant can be regulated by using the height-related protein HRP of the present invention.
