  1. Note: For hormone treatments, the leaves of seedlings were harvested at 0, 0.5, 1, 2, 4, 6, 8, 10, 12 and 24 h after treatment;
  2. For the environmental stress factor treatments, the leaves of seedlings were harvested at 0, 0.25, 0.5, 1, 2, 4, 6, 8, 10, 12 and 24 h after treatment;
  3. “**” and “*” indicate significant difference at P < 0.01 and P < 0.05, respectively;
  4. “-” represents no change and weak upregulation; “D” represents significant reduction in MAPK gene expression after treatment;
  5. “/” represents absent data. The Student’s t-test was performed between treated samples and untreated samples.
