Elicitor-enhanced accumulation of Inh I in excised wild-type and PG βS-AS tomato plants. Excised tomato leaves were supplied through their cut petioles with either 0.01 m phosphate buffer (pH 6.0; Control) or with the buffer containing each of the following elicitors for 30 min under light: 25 nm systemin (Sys), 250 μg mL^–1 oligo-GalUA (OGA), or 100 μm JA. The leaves were transferred to water and incubated for 24 h under light and then assayed immunologically for Inh I content. Data are means ± sd; n = 6.
