Interest in so-called functional foods, i.e., foods that promote health and disease prevention, is increasing. Consumption of plant polyphenols has been implicated in the prevention of age-related diseases, cardiovascular disease and cancer. AtMYB12 and AtMYB111, which were originally identified as flavonol-specific transcriptional activator in Arabidopsis thaliana, induces the accumulation of high levels of polyphenols in tobacco and tomato plants. In this study, we determined that the transcription factor AtMYB11 as its close homologs, AtMYB12 and AtMYB111, regulate flavonoid and caffeoylquinic acid biosynthesis in tomato and tobacco plants. Constitutive expression of AtMYB11 enhanced the expression
