Abstract: The present invention relates to a method for targeted inactivation of transcription factor using an artificial small interfering peptide and a use thereof. According to the present invention, an artificial small interfering peptide (a-siPEP) as a truncated from of the transcription factor for regulating transcription by dimerization was produced. It was also confirmed that, as a-siPEP forms a heterodimer with a transcription factor, DNA binding and transport into a nucleus of the transcription factor are inhibited, so that inactivation of the transcription factor is achieved at protein level. The method for inhibiting transcription factor activity using a-siPEP can replace a gene knock-out method and it allows protein-level inhibition of a transcription factor. Also, it is a transcription regulation method with high precision and high efficiency that can be applied for both monocot and dicot plants.
