From: Switchgrass PvDREB1C plays opposite roles in plant cold and salt tolerance in transgenic tobacco
Overexpressing PvDREB1C compromised the cold tolerance in tobacco. a Electrolyte leakage rates of tobacco exposed to 4 °C for 24 h. b, c Survival rate and phenotype of tobacco 2 days after −4 °C treatment for 3 h. Data are means of 18 plants of each line with two independent experimental repeats. Data are represented as mean ± SE, and different letters above bars indicate a significant difference at P < 0.05
