Figure 1.

Saturation curves obtained with labeled elicitins and corresponding Scatchard plots (insets). Plasma membrane preparations were incubated with various concentrations of ¹²⁵I-cryptogein (A), ¹²⁵I-cinnamomin (B), ¹²⁵I-capsicein (C), or ¹²⁵I-parasiticein (D). Nonspecific binding was measured in the presence of a 10 μm concentration of the corresponding nonlabeled elicitin and was subtracted from total binding to give the saturation curves. Experiments were repeated at least three times. Results are means ± sd.
