*4.5. Yeast One-Hybrid Assay*

To perform the Y1H assay, the full length of PheDof12-1 was cloned into the pGADT7-Rec2 bait vector, and the promoter sequence of PheCOL4 was cloned into the pHIS2 prey vector (Supplementary Table S1). The lithium acetate method was used to transform into the Y187 strain. The transformed yeast cells were selected on SD/-Trp/-Leu and SD/-Trp/-Leu/-His/-3AT/X-α-Gal plates at 30 ◦C for 3–5 days.
