Abstract Tree peony cultivars with yellow flowers are rare and valuable, but the molecular mechanism of pigment accumulation is not clear. In this study, the petal transcriptome of three developmental stages were sequenced to determine the differentially expressed genes (DEGs) regulating yellow flowers color. The results showed that 10,842 and 12,022 DEGs were screened in stage 1 vs. stage 2 and in stage 2 vs. stage 3, respectively. Through analysis of flavonoid structural genes (FSGs), we found that the transcription level of DFR was very low in the three developmental stages. In a small group of cultivars, the… More >
