The extraction of phytohormones and camalexin was performed as described (30 (link)). The compounds were quantified by HPLC-ESI-SRM in a Thermo Fisher TQS-Altis Triple Quadrupole Mass Spectrometer coupled to a Thermo Scientific Vanquish MD HPLC system. The chromatographic separation was carried out in a UPLC column (Agilent Eclipse Plus C18, RRHD, 1.8 um, 2.1 × 50 mm), and the compounds were eluted using water (A) and acetonitrile (B) as mobile phase at 0.6 mL/min and in a gradient elution mode as following: 10% B for 0.5 min, 10–55% of B at 4.5 min, 55–100% B at 4.7 min, 100% until 6.0 min, 100–10% B at 6.1% and 10% until 8 min. The column was kept at 55°C. The statistical significance from three replicates was evaluated by ANOVA followed by Tukey Test (Tukey HSD).
