Identification of PTI-related phenolic compound acetosyringone by HPLC-DAD-MS using analytical standard in Nicotiana benthamiana. a HPLC-DAD analysis of phenolic compounds from PTI-induced and water-treated control N. benthamiana leaves detected at 298 nm. PTI was induced by P. syringae pv. syringae hrcC- bacteria, water was injected as control. Samples were taken at 2, 4, 6 hpi. b MS spectra of AS had the expected m/z values in both positive and negative modes, identical to that of the standard. c) Identity of acetosyringone was supported by the similar UV spectra of the analytical standard and the unknown peak. Abbreviations: AS: acetosyringone, ESI+, ESI-: electrospray ionization positive and negative modes, Std: standard, W: water
