Characterization and Expression Profiling Analysis of Calmodulin Genes in Response to Salt and Osmotic Stresses in Pear (Pyrus bretschneideri Rehd.) and in Comparison with Arabidopsis

Figure 6

Expression of PbCaM genes in response to salt and osmotic stress. Shoots with young leaves were exposed to 1/2 MS solution containing 200 mM NaCl or 15% (w/v) polyethylene glycol (PEG6000) for the salt treatment (a) or osmotic treatment (b). Leaves were sampled at 0, 12, 24, and 48 h and were subsequently used for QRT-qCR analysis. All of the experiments were examined using three biological replicates and three technical replicates for all of the genes. The data was shown using the mean ± standard deviation (SD). The error bars represent the SDs of nine replicates.
