The transcription factor complex CmAP3-CmPI-CmUIF1 modulates carotenoid metabolism by directly regulating carotenogenic gene CmCCD4a-2 in chrysanthemum.

ABSTRACT: Carotenoids are one of the most important pigments for the coloring in many plants, fruits and flowers. Recently, significant progress has been made in carotenoid metabolism. However, the specific understanding on transcriptional regulation controlling the expression of carotenoid metabolic genes remains extremely limited. Anemone-type chrysanthemum, as a special group of chrysanthemum cultivars, contain elongated disc florets in capitulum, which usually appear in different colors compared with the ray florets since accumulating distinct content of carotenoids. In this study, the carotenoid composition and content of the ray and disc florets of an anemone-type chrysanthemum cultivar 'Dong Li Fen Gui' were analyzed by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/
