CtMYB1 regulates flavonoid biosynthesis in safflower flower by binding the CAACCA elements.

ABSTRACT:

Background

Safflower (Carthamus tinctorius L.) is a valuable herb known for its flowers, which are rich in flavonoids and are used for promoting blood circulation and preventing atherosclerosis. However, the molecular regulation of flavonoid biosynthesis in safflower is still poorly understood. In this study, we identified a AtMYB12 homologous gene, CtMYB1, in safflower and characterized its sequence. The flower protoplast transient expression system and virus-induced gene silence (VIGS) technique were established in safflower and we tested the role of CtMYB1 in the regulation of flavonoid biosynthesis. The correlation between CtMYB1 and flavonoid synthesis genes was analyzed using a molecular interaction assay.

Results

Flower protoplasts transient expression showed that fla
