Figure 5: (A)-Analysis of anthocyanin accumulation in in vitro cell cultures (Callus), as well as in different development stages of muscadine berry skins (Mature, Veriason, and green skins). Mean values with different small letters are significantly different at (p=0.01). The accumulation pattern of anthocyanins follows the pattern of expression of VrF3H. (B) The expression analysis of VrF3H in different tissues using real-time PCR.
