| Summary: | Clematis lanuginosa, a valuable ornamental plant in Zhejiang Province, China, produces flowers that are blue–purple, a rare flower colour. In this study, to explore the anthocyanin synthesis mechanism involved in flower colour formation in C. lanuginosa, metabolome, and transcriptome sequencing was performed at six flower development stages. Metabolome analysis revealed 25 anthocyanin compounds and 22 differentially expressed metabolites. Cyanidin-3,5-O-diglucoside, cyanidin-3,5,3'-O-triglucoside, cyanidin-3-O-rutinoside-5-O-glucoside, delphinidin-3-O-glucoside, and petunidin-3-O-glucoside may promote the formation of blue–purple colour in flowers. The combined analysis results revealed that the transcript41913_f2p0_1152 gene (MYB-like) may be a key gene in C. lanuginosa blue–purple flower colour development. These results provide the basis for further research on the blue–purple flower colour of C. lanuginosa. |
