Fig. 2

Identification of signatory biomarkers associated with the response of tobacco cells to 100 μM of the inducing agents azelaic acid (Aza) and hexanoic acid (Hxa). Shown are the (a) OPLS-DA S-plots and (b) VIP plots of analytes (Rt and m/z values) present in extracts derived from 12 h Aza-treated cells in comparison to the 0 h controls. Equivalent graphs for extracts from Hxa-treated cells (0 h vs. 12 h) are shown in (c) and (d) respectively. The x-axes of the OPLD-DA S-plots represent the modeled covariance or p [1] and the y-axes the modeled correlation or p(corr) [1]. The rectangles indicate the extraction of ions representing significant biomarkers (cut off: ± 0.10) responsible for the difference between the control and treated cells. The VIP plots are annotated with Rt and m/z values
