Functional Descriptions:
- The anthocyanin biosynthesis pathway was strongly downregulated in star petals, including its major regulator ANTHOCYANIN2 (AN2).
- We established that PhDEF directly binds to the AN2 terminator in vitro and in vivo, suggesting that PhDEF might regulate AN2 expression and therefore petal epidermis pigmentation.
- Therefore, we conclude that PhDEF binds to the terminator region of AN2 in planta, and that PhDEF is a putative direct regulator of AN2 expression in the petal epidermis.
- Ectopic expression of AN2 in petunia leaves is sufficient to trigger anthocyanin accumulation in this tissue, by inducing AN1 expression among others.
