SDS–PAGE and western blot analysis of proteins from root exudates of non-elicited (C, control) and elicited (E1 and E2) plants. Proteins were run on gels, blotted and probed with antisera recognizing either arabinogalactan protein epitopes JIM13 (A), LM2 (B) and JIM15 (C) or extensin epitope LM1 (D). The epitopes recognized by each antibody are presented in Table 1. E1 and E2 correspond to the elicitor concentrations used (1 mg mL⁻¹ for E1, 2 mg mL⁻¹ for E2).
