• Using suspension cultures of Centaurea cyanus L. cells, in which the biosynthesis of anthocyanin is induced by illumination with UV-containing white light and in which the level of pigment can be controlled, we examined the sensitivity of the cells to both UV-B and UV-C irradiation and the formation of pyrimidine dimer as a result of exposure to UV light, with a special reference to the level of accumulation of anthocyanin pigment in the cells. The sensitivity of the cells to UV-B or UV-C decreased as their anthocyanin content increased. Furthermore, the extent of formation of pyrimidine dimers induced by irradiation with UV-B or UV-C light was found to be reduced in cells with accumulated anthocyanin. Both the extent of resistance to UV irradiation and the reduction in the extent of formation of dimers as a result of exposure to UV light were correlated with the levels of accumulated anthocyanin pigment in the cells. The results show that anthocyanin, a kind of flavonoid, plays a role in protecting cells from the adverse effects of UV light.
