qPCR based transcription profiling of the four SOS1 genes in response to salinity stress. Relative transcript abundances in the root (a), stem (b) and leaf (c). The relative expression in all tissues and time points was first compared to the reference genein each species and then calculated using the expression value at the initial time (0 h) in the root of CmSOS1. Data are presented as mean ± SE (n = 3). Actin was used as reference gene
