Briefings

Nick Desnoyer, a plant biologist at the Sainsbury Laboratory in Norwich, England, is developing the Paintunia, a living petunia canvas that responds to dexamethasone molecules to express cyan, magenta, and yellow pigments via inducible genes. The first version of Paintunia was created by turning an existing Arabidopsis research plant into pink micro-roses, and the project involves engineering multiple biosynthetic pathways for future iterations. The video was filmed in October 2026, with limited coverage of the full design process and future plans.

Key points

• Nick Desnoyer is a postdoctoral fellow at the Sainsbury Laboratory in Norwich, England, working on the Paintunia project.
• The Paintunia is an engineered petunia that uses dexamethasone molecules to trigger gene expression and produce cyan, magenta, and yellow pigments in specific floral regions.

Context and limitations

Coverage is limited to the initial announcement and demonstration of the first Paintunia version; the full design process, future iterations, and the complete plan for a botanical garden are not detailed.
