Figure 6. miR393 early regulates redox components under salt.

Seven dpg WT and mir393ab seedlings were transferred onto liquid ATS medium supplemented with 100 mM NaCl. After 12 h of initial treatment (A) H₂O₂ accumulation, (B) APX activity and (C) CAT activity were measured. (D) Seven dpg mir393ab, tir1-1, tir1-1 35Spro:TIR-Myc and WT seedlings were treated with 100 mM NaCl for 3 d. Chlorophyll content was measured and expressed as percentage of untreated seedlings. Data are mean values (±SE) of three independent experiments. Different letters indicate a significant difference at P≤0.05 (Tukey test).
