Mechanisms of bullseye boundary formation in Hibiscus trionum petal patterning
… cell fate specification is achieved across the petal epidermis remains obscure. Hibiscus trionum is an emerging model system producing flowers with a striking bullseye pattern on the adaxial petal epidermis. Cells in the proximal region are flat, elongated with cuticular striations and …

Flavonoid diversification in Hibiscus and its impact on petal pattern evolution
… through distinct pigmentation patterns on their petals. While their ecological significance is known, the developmental and evolutionary origins of these patterns remain less understood. In Hibiscus trionum, a new model system, bullseye patterns are formed by flavonoid pigments including …

Mechanisms controlling cell shape patterning in petals
… often exhibit various patterns on their petals. These patterns allow entomophilous plants to attract pollinators and also help them deal with abiotic stress such as UV-levels and water loss. While previous research largely focused on pigmentation patterns, structural patterns created by …

Understanding the development, evolution, and function of bullseye pigmentation patterns in Hibiscus trionum
… important biotic and abiotic functions. These petal patterns are created by spatial differences in pigmentation, cell shape and texture of the adaxial petal epidermis. The mechanisms controlling formation and evolution of these patterns, and their exact role in plant-animal communication are …

Polarity establishment and signalling mechanisms controlling patterning in Hibiscus Trionum petals
… and pigments combine with each other to pattern petals surfaces and these patterns can mediate plant-animal communication. Hibiscus trionum flowers produce a striking bullseye pattern by specifying cells with different pigmentation, shape, and texture in different regions of the adaxial petal …
