Figure 7From: Thiamine modulates metabolism of the phenylpropanoid pathway leading to enhanced resistance to Plasmopara viticolain grapevineQuantitative determination of quercetin 3- O -glucoside flavone in grapevine plants by HPLC-DAD. Plants were treated with 30Â mM thiamine (solid bars) or sterile distilled water (white bars) and leaves were harvested at different time intervals post-treatment (dpt). Data are the mean of 3 independents experiments.Back to article page
