Lilium spp., one of the world’s famous ornamental flowers, is mainly cultivated as cut flower, whose ornamental value lies in the floral organ. It usually comes in colors of red, orange, white and pink with the absence of blue or purple. To explore the variation mechanism of different colors of Lilium cernum, the floral organs of Lilium cernum with different colors and same habitat were used as materials in this study. A high-throughput sequencing technique applied used to establish the process of flower development and the transcriptome database of the two types of flowers. The structural genes and transcription factors of anthocyanin biosynthesis pathway were screened differentially.
The results revealed that a total of 57521 Unigenes were obtained by sequencing. Compared the expression differences of structural genes of anthocyanin synthesis in floral organs at different stages, 5 structural genes were screened out. These structural genes and transcription factors are speculated to be closely related to the regulation of anthocyanin synthesis. At the same time, it is believed that pink Lilium cernum may be caused by the flowering process, during which the color conversion stage is not completely completed.
