Flavonoid Synthesis in Plants

Studies have mainly concerned production and accumulation of diverse flavonoids in angiosperms [18-20], At the same time, the major steps leading to various types of llavonoid subgroups by plant enzymes have also been examined in cell-free systems [21], 

Plants have many enzymes involved in secondary metabolism, its precursor proteins and ultimate metabolites. 

In addition, the initial source of variation in enzyme functions might depend on random mutations that occurred in their genes and the chromosomal rearrangements for enzymes which produce diverse llavonoid pigments as their final functional phytochemicals. The functional variations might occur in different parts of the plant, generating different evolutionary paths [22],
