Sep 28, 2012 Flavonoid biosynthesis. The first enzyme specific for the flavonoid pathway, chalcone synthase, produces chalcone scaffolds from which all flavonoids derive. Although the central pathway for flavonoid biosynthesis is conserved in plants, depending on the species, a group of enzymes, such as isomerases, reductases, hydroxylases,Jul 17, 2013 Biosynthetic Pathway of Flavonoids in Plant Cells Flavonoids (in particular anthocyanins and PAs) are synthesized along the general phenylpropanoid pathway by the activity of a cytosolic multienzyme complex, known also as flavonoid metabolon, loosely associated to the cytoplasmic face of the endoplasmic reticulum (ER). flavonoid biosynthetic pathway in plants

Feb 01, 1994 A special class of flavonoid polymers, the tannins, plays a structural role in the plant. Yet other classes of flavonoids, flavonols and anthocyanins, have been implicated in the attraction of pollinators. Certain flavonoids participate in the interaction between plants and other organisms such as symbiotic bacteria and parasites.

Flavonoid biosynthesis is largely regulated at the transcriptional level due to the modulated expression of genes related to the phenylpropanoid pathway in plants. Jun 01, 2001 Schematic of the major branch pathways of flavonoid biosynthesis, starting with general phenylpropanoid metabolism and leading to the nine major subgroups: the colorless chalcones, aurones, isoflavonoids, flavones, flavonols, and flavandiols (gray boxes), and the anthocyanins, condensed tannins, and phlobaphene pigments (colored boxes).flavonoid biosynthetic pathway in plants In plants, there are essentially two distinct biosynthetic pathways for the synthesis of flavonoidbased compounds. They include the shikimic acid pathway generating the phenyl propanoids (C6C3) skeleton and the acetate pathway serving as a building block for polymeric 2carbon units ( Croteau et al. , 2000 ).
