Transformed colonies were plated onto minimal medium quadruple dropout (SD medium with –Leu/–Trp/–His/–Ade) containing 125 μM aureobasidin A and 4mg ml–1 X-α-Gal at 30 °C to test for possible interactions between MaERF9/MaERF11 and MaACS1/MaACO1 by their growth status and α-galactosidase activities.
