SlmiR168 and SlAGO1A expression profiles in JZ18 and JZ34 plants under normal K⁺ conditions and K⁺ deficiency conditions. Samples of leaves were collected at 0, 1, 3, 5, and 7 days after treatment. a. the miR168 expression levels in JZ18 seedlings under normal K⁺ and K⁺ deficiency conditions; b. the SlAGO1A expression levels in JZ18 seedlings under normal K⁺ and K⁺ deficiency conditions; c. the miR168 expression levels in JZ34 seedlings under normal K⁺ and K⁺ deficiency conditions; d. the SlAGO1A expression levels in JZ34 seedlings under normal K⁺ and K⁺ deficiency conditions. CK: normal K⁺ (4 mM); LK: K⁺ deficiency (0.5 mM). 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 CK
