Phenotypes of the ZmDHN15-overexpressing transgenic plants and wild-type controls in Arabidopsis under cold stress. (A,B) The germination rate of ZmDHN15 transgenic Arabidopsis with cold stress. (C,D) Root length statistics of transgenic Arabidopsis thaliana ZmDHN15 under cold stress. Scale bars represent 1 cm. (E) Three-week-old Col-0 and OE lines recovered to 7 d phenotype after 24 h treatment at 4 °C. (F) Statistics on the survival rate of three-week-old Col-0 and OE lines treated at 4 °C for 24 h and recovered for 7 d. Data were expressed as the mean of triplicate values, and the error represented the SD. Asterisks indicate statistically significant differences: Non-significant (ns), p < 0.05 (*).
