Abstract: The present invention discloses a method for increasing the sensitivity of a plant to a gibberellin inhibitor. The method for increasing the sensitivity of a plant to a gibberellin inhibitor provided by the present invention comprises the step of introducing an encoding gene of a protein into a recipient plant to obtain a transgenic plant; the transgenic plant has increased sensitivity to the gibberellin inhibitor compared to the recipient plant; the protein is a protein of the following a) or b) or c): a) a protein whose amino acid sequence is set forth in positions 1-821 of SEQ ID NO: 1; b) a protein whose amino acid sequence is set forth in SEQ ID NO: 1; c) a fusion protein obtained by attaching tag(s) to the N-terminus or/and C-terminus of a) or b).
