Maize ZmGAD1and ZmGAD2 conferred Cd tolerance in yeast. a The survival test of yeast strains transformed with ZmGADs on SG-Ura agar medium supplemented with 40 μM CdCl2 in the presence of 2% galactose. The photographs were taken 3 days post incubation, with three independent experiments. b Time-dependent growth curves of yeast transformed with ZmGADs in SG-Ura liquid medium with 30 μM CdCl2 and 2% galactose. The growth of the yeast cells was monitored at OD600. Data are presented as means ± SE (n = 3). Error bars indicate SE of three independent biological experiments. Statistical analysis was performed using SPSS20.0 software
