Carotenoids are an essential pigment that plays a critical role in floral color formation. Carotenoids are responsible for giving color to the flowers ranging from yellow to red. In carotenoids,α-carotene,β-carotene,and xanthophylls provide yellow color,while lycopene,astaxanthin,and capsanthin give red color to the flowers. In recent years,there are many studies on carotenoids related to floral color. In this paper,the latest research progress on the composition and metabolic regulation of carotenoids in ornamental plants was summarized from three aspects including effects of carotenoids on color,carotenoid biosynthetic and degradation pathway as well as the function of related genes and metabolic regulation of carotenoids,such as transcriptional regulation,epigenetic regulation and so on. Our study will provide a reference for the further study of floral color.

Key words: ornamental plant, floral color, carotenoids, metabolism, regulation
