Reduced Defenses in acd6-T Plants.
(A) Reduced SA levels in P. syringae–infected acd6-T plants. Plants were inoculated with 10 mM MgSO4 or Pto DC3000 at OD600 = 0.01. Samples were analyzed in triplicate. Asterisks indicate P < 0.05 at 12 h. FW, fresh weight.
(B) Reduced PR1 expression in P. syringae–infected acd6-T plants. Plants treated as in (A) were used for RNA isolation. This experiment was repeated twice with similar results.
