RD29A-LUC expression in response to NaCl treatment at different temperatures. Control treatments (−NaCl, white bars) at the specified temperatures were carried out with plants on filter paper saturated with MS salt solution; NaCl treatments (+NaCl, hatched bars) were treated with 300 mm NaCl in MS solution. Treatments at the indicated temperatures lasted for 4 h before luciferase imaging. For the 0°C treatments plants were incubated in the cold for 44 h before being transferred to filter paper for treatments with or without NaCl at 0°C for 4 h. Error bars represent ±sd (n = 15).
