Integrated transcriptomic and metabolomic analyses reveal the molecular mechanism of flower color differentiation in Orychophragmus violaceus.

ABSTRACT:

Introduction

Orychophragmus violaceus is a popular horticultural plant because of its bright purple flowers that are commonly found in parks and green belts. However, three flower colors (purple, light purple, and white) were observed in the wild-type O. violaceus. The molecular mechanism underlying the formation of these intriguing flower colors remains unknown.

Methods

Here, we combined metabolomics and transcriptomics to identify a pathway cascade leading to anthocyanin biosynthesis associated with flower color formation in O. violaceus.

Results and discussion

A total of 152 flavonoid metabolites were identified based on metabolomic data, most of which were quercetin and kaempferol. Comparative analysis of the metabolites among the three flower
