In horticulture, there is a constant need for ornamental plants with new characteristics, where the flower
color is one of the most important features that determines their commercial value. With the development
of genetic engineering methods, it has been possible to create plants with the desired flower
color which cannot be achieved by classical breeding or mutagenesis. The flower color in plants is determined
by the content of three plant pigments: anthocyanins, carotenoids and betalains. Up to date, the
greatest progress has been made by genetic modulation of anthocyanin biosynthesis. In this way, the new
flower colors have been achieved in at least 50 ornamental species, and some of these modified varieties
have been on market for many years. However, the alteration of flower color by manipulating the carotenoid
biosynthetic pathway has been documented in only a few ornamental species, and the research has
been significantly increased last few years. In this paper, the potential of this approach is considered, with
special reference to the results achieved on flower color alteration of pansy cultivars by introducing the
gene for capsanthin-capsorubin synthase.
