• Keywords: Flavonoid Biosynthesis

Plants synthesize secondary metabolites, including flavonoids, which play important role during various stresses for their survival. These metabolites are also considered as health-protective components in functional foods. Flavonols, one of the groups apart from performing several roles plants have been recognized potent phytoceuticals human health. Tomato fruits deficient this group flavonoids and an target enhancing accumulation flavonols through genetic manipulations. In present study, AtMYB12 transcription factor Arabidopsis has expressed under constitutive promoter tomato. Transgenic tomato lines exhibited enhanced chlorogenic acid (CGA) leaf fruit accompanied with elevated expression phenylpropanoid pathway genes involved flavonol biosynthesis. addition, global gene analysis suggested that modulates number molecular processes aromatic amino biosynthesis, phytohormone signaling stress responses. Besides this, a differential modulation leaves is reported study. Taken together, results demonstrate primary carbon metabolism other pathways by may lead to sufficient substrate supply content phenolics general particular.
