MYB17-DFR/LDOX Module Positively Regulates Cyanidin Deposition in Cinnamomum Camphora.

CcMYB17 enhances cyanidin accumulation by activating CcDFR and CcLDOX, leading to stem coloration in Cinnamomum camphora, with a key role in anthocyanin biosynthesis.

• Why it matters: Understanding the genetic regulation of leaf and bark coloration can improve ornamental traits and diversify landscape options, addressing the limitations of the traditional green and brown varieties.
• What they did: Researchers characterized a coloured variety, 'Gantong 1', and used yeast one-hybrid, luciferase reporter, and multi-omics analyses in a poplar model to investigate CcMYB17's role in cyanidin biosynthesis.
• The result: The findings reveal that CcMYB17 positively regulates cyanidin and delphinidin accumulation, providing a molecular basis for breeding colorful woody trees and enhancing ornamental plant development.
