Abstract excerpt

MAIN CONCLUSION: This work shows that, in tobacco, the ectopic expression of VvMYBPA1 , a grape regulator of proanthocyanidin biosynthesis, up- or down-regulates different branches of the phenylproanoid pathway, in a structure-specific fashion. Proanthocyanidins are flavonoids of paramount importance for animal and human diet. Research interest increasingly tilts towards generating crops enriched with these...
