The present application uses the Schizonepeta citonellol synthase (StLS) gene promoter as a decoy, and uses a biological screening method to screen two MYB transcription factors, namely StMYB76 and StMYB13, which are involved in the regulation of Schizonepeta pulegone biosynthesis. The nucleotide sequences of the two genes are shown in SEQ:NO.1 and SEQ:NO.2. Both MYB transcription factors can bind to the StLS promoter element and activate its expression; can significantly enhance the transcript abundance of Schizonepeta pulegone synthesis related genes StLS, StL3OH, StIPD and StPR; and can promote the accumulation of pulegone in Schizonepeta leaves. The present application can be used for the transcriptional regulation of plant pulegone biosynthesis, and provides a theoretical basis and research direction for improving the regulation mechanism and molecular breeding of Labiatae plant volatile oil synthesis.
