Performance of transgenic plants under cold: Proline concentration (A) and Electrolyte leakage (B) of wild-type and LlaCIPK-overexpressing transgenic plants. (C) Survival rates of 4 weeks old transgenic plants and wild-type plants after 7 days of cold treatment (4 °C). For proline concentration and electrolyte leakage 2-week-old WT and transgenic seedlings were exposed to low temperature 4 °C for 24 h. Electrolyte leakage was expressed as a percentage of total electrolytes. The experiments were repeated at least three times with three different transgenic lines designated as L2, L3 and L5. Vertical bars represent ± S.E. *** indicates significantly different values between treatments (p < 0.001).
