Integrated metabolomics and transcriptome analysis on flavonoid biosynthesis in flowers of safflower (Carthamus tinctorius L.) during colour-transition.

ABSTRACT:

Background

Safflower (Carthamus tinctorius L.), well known for its flower, is widely used as a dye and traditional Chinese medicine. Flavonoids, especially flavonoid glycosides, are the main pigments and active components. However, their biosynthesis is largely unknown. Interestingly, the colour of flowers in safflower changed from yellow to red during flower development, while much of the gene and chemical bases during colour transition are unclear.

Methods

In this research, widely targeted metabolomics and transcriptomics were used to elucidate the changes in flavonoid biosynthesis from the gene and chemical points of view in flowers of safflower during colour transition. The screening of differential metabolites depended on fold change and variable importance in pr
