UHPLC-MS diagnostic ions (ESI-negative mode) used for the identification of biomarkers in LPS, CHT and FLG-treated tobacco cells.

The common and unique biomarkers in response to MAMP elicitation are shown and compared to the phytohormones salicylic acid (SA), methyljasmonate (MJ) and absiscic acid (ABA). Biomarkers derived from both SIMCA and XC-MS analyses are listed. Annotated metabolites that were negatively correlated with the various treatments are indicated in italics and open circles.
