Comparison of CTK and ABA contents in low K⁺ sensitive (JZ18) and low K⁺ tolerant (JZ34) tomatoes under K⁺ deficiency stress conditions after 24 h, 3 days, and 7 days (a and b); CTK and ABA contents of JZ18, 35S:SlmiR168a and 35S:rSlAGO1 under normal condition (c). CK: normal K⁺ (4 mM); LK: K⁺ deficiency (0.5 mM). The experiments were repeated three times. Error bars indicate the means ± SE of three independent replicates. * Significant differences with P < 0.05 determined using a Duncan’s test compared with the control
