Effect of thymol on Na+ and K+ content and the expression of Na+ transporter genes in tobacco seedlings under salt stress. Na+ and K+ flux in tobacco roots and leaves (a-d). Na+ and K+ content in tobacco seedlings (e and f). Relative expression level of NtSOS1, NtHKT1 and NtNHX1 (g). Different lowercase letters indicated that the mean values of three replicates were significantly different between the treatments (P < 0.05, ANOVA, LSD). The expression levels of NtSOS1, NtSOS1 and NtSOS1 in control were defined as “1”. Data are means ± SE (n = 3)
