Effect of 3OC6-HSL on cellular ionic homeostasis in Arabidopsis and wheat. 2-week-old seedlings were treated with 1 μM 3OC6-HSL or/and 150 mM NaCl as indications. The contents of Na+ and K+ were measured and Na+/K+ ratio were calculated after treatment for 14 days in Arabidopsis (ac) and 10 days in wheat (df). 20-day-old seedlings were treated with 1 μM 3OC6-HSL or/and 150 mM NaCl as indications. The relative gene expression of SOS1 (g), SOS2 (h) and SOS3 (i) were measured by qRT-PCR after treatment for 6 h in Arabidopsis. Values are mean ± SD of three independent experiments. Different letters indicate statistically significant differences (P < 0.05, Duncan’s test)
