Quantitative RT-PCR detection of the expression levels of the 11 CrPIPs responding to different stresses (600 mM NaCl, 150 mM NaHCO₃, 300 mM mannitol, and 100 mM ABA) in C. rosea seedling plants. a 5 CrPIP1s. b 6 CrPIP2s. Relative expression values were calculated using the 2 − ΔCt method with housekeeping gene CrEF-α as reference gene. Bars show mean values ± SD of n = 3–4 technical replicates
