Transcription activation ability of MaMybA. Yeasts transformed with the pGBKT7/MaMybA vector (positive control (pGBKT7-53 + pGADT7-T) and negative control (pGBKT7)), were each cultured in SD/-Trp media, SD/-Trp media with 40 mg mL− 1 X-α-gal, and SD/-Trp media added to 40 mg mL− 1 X-α-gal and 200 ng mL− 1 AbA.
