  • a The values for both rcn1 and cantharidin-treated (CT) wild-type were compared with wild-type values by Student's t test and had P values >0.05 for all tests.

  • b The values for minus and plus NPA were compared by Student's t test for wild type, rcn1, and cantharidin-treated wild type and had P values >0.05 for all tests.

  • c The average ±se of 29 to 42 plants from three to five experiments are reported.

  • WT, wild type.
