Expression analyses of flavonoid biosynthetic genes in CrV and CrW. (A) RT-PCR analysis of nine different flavonoid biosynthetic genes and the β-actin gene (internal control). Gene names and PCR cycles are shown to the left and right of each panel, respectively. (B) Northern blot analysis of F3H, F3′H and F3′5′H genes in torenia flowers. rRNA was used as a total RNA loading control.
