Conical petal epidermal cells, regulated by the MYB transcription factor MIXTA, have an ancient origin within the angiosperms.
Conical epidermal cells occur on the tepals (perianth organs, typically petals and/or sepals) of the majority of animal-pollinated angiosperms, where they play both visual and tactile roles in pollinator attraction, providing grip to foraging insects and enhancing colour, temperature and hydrophobicity. To explore the evolutionary history of conical epidermal cells...Reed, Alison ; Rudall, Paula J ; Brockington, Samuel F ; Glover, Beverley J

Phylogenetic relationships based on nuclear and plastid DNA sequences reveal recent diversification and discordant patterns of morphological evolution of the Chilean genera of Gilliesieae (Amaryllidaceae: Allioideae)
Gilliesieae are a South American tribe of Amaryllidaceae characterized by high floral diversity. Given different taxonomic interpretations and proposals for generic and specific relationships, a representative phylogenetic analysis is required to clarify the systematics of this group. The present study provides a framework for understanding phylogenetic relationships and contributing to...Escobar, Inelia ; Ruiz-Ponce, Eduardo ; Rudall, Paula J ; Fay, Michael F ; Toro-Núñez, Oscar …

Colourful cones: how did flower colour first evolve?
Angiosperms that are biotically pollinated typically produce flowers with bright and contrasting colours that help to attract pollinators and hence contribute to the reproductive success of the species. This colourful array contrasts with the much less multicoloured reproductive structures of the four living gymnosperm lineages, which are predominantly wind pollinated,...Rudall, Paula J
