Light requirements in anthocyanin synthesis

Kernels of c1 and c2 developed pigments, with some of the substrates, only in the presence of light. The c1 kernels treated with cinnamic acid and caffeic acid failed to show any response when placed in the dark for 72 hours. These kernels were then exposed to light for about 20-24 hours and developed pigment, suggesting that light is essential for pigment synthesis. Anthocyanin synthesis was generally seen on the sides that were directly exposed to light. When kernels were placed in a uniform field of light, the pigment was observed on all sides.
