Petunia flower colors are mainly due to flavonoids. The flower color of commercial varieties of Petunia hybrida was successfully modified by the suppression of endogenous flavonoid biosynthetic genes, the expression of a hetelorogous flavonoid biosynthetic gene, and the combination of both. Flower color changed from purple to almost white or from purple to red by the suppression of the endogenous gene expression, from red to orange by the down-regulation of the flavonoid 3 hydroxylase gene and… CONTINUE READING
