Effect of cold stress on visual damage symptoms of wild-type and CaMBF1 -overexpressing transgenic plants. A, Wild-type Arabidopsis (Col-0) were subjected to cold stress for 2 h; B, Transgenic plants were subjected to cold stress for 2 h; C, Wild-type plants were subjected to cold stress for 6 h; D, Transgenic plants were subjected to cold stress for 6 h; E, Wild-type plants were subjected to cold stress for 24 h; F, Transgenic plants were subjected to cold stress for 24 h; G, Wild-type plants were subjected to cold stress for 48 h; H, Transgenic plants were subjected to cold stress for 48 h. The differences among treatments are marked with white arrows in rosette leaves. Photographs show plants subjected to cold stress for 48 h.
