Time-course quantification of γEC and (h)GSH in Peking and PI88788 (resistant) and Williams 82 (susceptible) soybean roots. Infected and uninfected root γ-glutamylcysteine (γEC) (A), glutathione (GSH) (B), and homoglutathione (hGSH) content (C) at 5, 10, and 15 days post infection. C and N represent uninfected and infected roots, respectively. The data (six samples from three independent biological experiments) are reported as the mean ± standard error. * indicates a statistically significant difference (p < 0.05).
