Physical interactions between MaERF9 and -11 and MaACS1 and MaACO1
The interactions between MaERF9 and -11 and MaACS1/MaACO1 were investigated using the Matchmaker Gold Yeast Two-Hybrid System. MaACS1, MaACO1 and MaERF9 and -11 coding sequences were subcloned into pGADT7 and pGBKT7 vectors for the Y2H assay, respectively. As shown in Fig. 6, yeast cells co-transformed with a positive control (pGBKT7-53 + pGADT7-T) and MaERF9 or MaERF11 with MaACO1, could grow on selective medium (synthetic medium lacking tryptophan, leucine, histidine, and adenine) supplied with the toxic drug aureobasidin A, and turned blue in the presence of the chromagenic substrate X-α-Gal, indicating that MaERF9 or MaERF11 physically interacted with MaACO1. However, yeast cells harbouring MaERF9 or MaERF11 with MaACS1, and the negative controls, could not grow on the selective medium and did not turn blue under the same conditions (Fig. 6).
