| Description |
Thirty-six metabolites (17 amino acids, 18 GSLs, and 1 flavonoid; Table S1) were separated on UPLC through a reverse phase column (50 9 2.1 mm,HSS T3 1.8 μm; Waters) (Table S1) and detected using ZQ mass spectrometers (Waters) with an electrospray ionization (ESI) interface (positive mode for amino acid analysis; negative mode for glucosinolates and flavonoid analysis; capillary voltage, +3.0 and -3.0 keV; cone voltage, +25 and -40 V; source temperature, 120℃; desolvation temperature, 350℃; cone gas flow, 50 L/h; desolvation gas flow, 600 L/h). |
