The differential relative transcript expression level of StSnRK2.1 to StSnRK2.8 under 5% PEG stress treatments; data represent the means ± SD of three replicates and different letters indicate significant difference at P < 0.05. Total RNA was extracted from four-week-old plants subjected to 5% PEG stress treatments for 2–48 h. Y-axis showed the transcript fold to that in the CK
