Abstract:

In this review, we listed the types, structures and colors of common carotenoids in nature, and focused on the ornamental plants with carotenoids as the main pigment components. The differences in composition and content of carotenoids in petals of different ornamental plant species and different color varieties were illustrated with examples, and the relationship between flower color and carotenoid components were discussed. Moreover, the effect of genes expression level related to carotenoid biosynthesis pathway on flower color were analyzed, and the cases that changing flower color by regulating the synthesis and degradation of carotenoids through genetic engineering were reviewed. Overall, we provided ideas of regulating carotenoid components and contents to accurately and directionally change plant flower colors to obtain new flower varieties with high ornamental value.

Key words: carotenoids, contents, biosynthesis, genetic engineering, flower color breeding
