  1. 1thaxtomin A and isoxaben levels from root tissue were quantified after 24 h on treatment media which contained either 1 μM thaxtomin A ± 3 μM NPA; or 100 nM isoxaben ± 3 μM NPA. Results are the means ± SE of three replicates.
  2. a, bStatistically different values (t-test, P < 0.05) are indicated with a different letter in each column.
