Evaluation of abilities of cold resistance in SlSLD-silenced tomato leaves.
(A) Phenotype of SlSLD-silenced tomato after exposure to 4 °C. REL (B), MDA content (C), water soluble carbohydrate content (D), SOD activity (E), POD activity (F), and chlorophyll content (G) were analyzed after chilling treatment for 6 hours. Data represent the mean value ± standard deviation (n = 5). CK, tomato leaves injected with TRV vector. SlSLD: TRV, SlSLD-silenced tomato leaves. *p ≤ 0.05 compared with CK.
