Story summary
- OvP-37 produced purple flowers with 4.39 mg/g anthocyanin. OvW-1 yielded white flowers.
- Purple petals show upregulation of anthocyanin biosynthesis genes. ANS is higher than in OvW-1.
- Across the genome, 98 anthocyanin-related genes on 12 chromosomes were identified in O. violaceus.
- Two DNA insertions in the OvANS promoter region may silence OvW-1.
- ANS mutations drive purple-to-white color change in O. violaceus.
