Figure 4
Levels of phenolic compounds in transgenic tobacco lines expressing Medicago WRKYs. Selected regions of HPLC chromatograms show soluble (A) and wall bound (B) phenolic compounds. Insets show the UV spectra of identified peaks. (C) and (D) show relative levels (peak areas) of soluble and wall bound phenolic compounds in control and transgenic lines. Control plants harbor pBI121. Error bars indicate standard error from three biological replicates (control and transgenic lines – T0 generation).
