Figure 4.

Effects of increasing concentrations of elicitins on extracellular pH of tobacco cell suspensions. Cells were treated with cryptogein (A), cinnamomin (B), capsicein (C), or parasiticein (D). Elicitin concentrations were 5 nm (♦), 10 nm (+), 25 nm (▴), 50 nm (▵), 75 nm (▪), 100 nm (□), 250 nm (•), and 500 nm (○). Experiments were repeated three times. The figure corresponds to a representative experiment.
