Figure EV1. Transgenic plants overexpressing ARR1/10/12 all show hypersensitivity to salt stress compared with that of wild type.

• A–D
  Four‐day‐old seedlings of 35S:ARR1:MYC, 35S:ARR10:YFP, and 35S:ARR12:YFP were transferred to 1/2 MS medium supplemented with 50 mM or 75 mM NaCl. Pictures were taken, and the elongated root length was determined 3 days later (A and B). Changes in survival rates (C) and fresh weights (D) were examined after 10 days of salt treatment. Scale bar, 1 cm.

Data information: In (B–D), data are means of three biological replicates ± SD (n = 60 for (B), and n = 12 for (C) and (D)). ***, and **** indicate significant difference to the corresponding controls with P < 0.001 and P < 0.0001, respectively (Student's t‐test).
