Additional file 3: Figure S2. of Flavonoids and darkness lower PCD in senescing Vitis vinifera suspension cell cultures

Mass spectra obtained using Multi-stage Mass Spectrometry (MSn) for analysis of alcoholic extracts obtained by V. vinifera (cv. Limberger) suspension cell cultures. Upper spectrum represents the spectrum obtained from crude extract obtained from RSC grown for 6 days under light. Middle spectrum and lower spectrum represent spectra from two different fractions eluted with H2O and methanol from C18 SPE column, respectively. (TIF 47 kb)
