Chromatographic characterizations of phytomelatonin detected in Valencia sweet orange leaves after infection with Ca. L. asiaticus and/or infestation with D. citri using targeted GC-MS-SIM. A, Chromatogram of melatonin authentic standard (20 ppm). B, Phytomelatonin from healthy (control), Ca. L. asiaticus-infected, D. citri-infested, or double-attacked (Ca. L. asiaticus infected and D. citri infested at the same time) Valencia sweet orange leaves. C to E, Mass spectra of melatonin authentic standard (200 ppm) in full scan mode, melatonin authentic standard (20 ppm) in SIM mode, and phytomelatonin from Valencia sweet orange leaves in SIM mode, respectively.
