Tree peony variegated flowers show a small insertion in the F3'H gene of the acyanic flower parts.

ABSTRACT:

Background

The tree peony (Paeonia suffruticosa Andr.) cultivar 'Er Qiao' is appreciated for its unstable variegated flower coloration, with cyanic and acyanic flowers appearing on different branches of the same plant and occasionally in a single flower or petal. However, the variegation mechanism is still unclear.

Results

In this study, we found significantly higher contents and more diverse sets of anthocyanins in the cyanic petals than in the acyanic petals. Comparative transcriptome analysis between the two flower types revealed 477 differentially expressed genes (DEGs). Quantitative real-time PCR results verified that the transcript levels of the flavonol synthase (FLS) gene were significantly increased in the acyanic petals. Furthermore, we found that a GCGGCG insertio
