Figure 6.

Exemplary HPLC chromatograms of three analog leaf extracts of BCPmlo5 from independent experiments (different plant batches). Noninoculated samples were taken on the 8th d after seed germination for determination of total SA. For unknown reasons, extracts showed differing contents of SA, although the contents of other compounds did not differ. The middle and the lower chromatogram show low contents of endogenous 2-methoxybenzoic acid (2MBA). The upper line represents an extract containing 2MBA as an internal standard. rel. f., Relative fluorescence.
