Our area of interest is the evolution and development of floral traits that are important in attracting animal pollinators. By understanding how plants build traits that attract particular animals we aim to understand the diversification of the flowering plants.
We are particularly interested in petal characters such as colour, texture and insect-mimicking spots. We use molecular genetic, systematic and developmental techniques to address these problems, and our lab incorporates a bee behavioural facility to explore pollinator responses.
Understanding plant-pollinator interactions in this integrated way provides us with tools to contribute to the design of strategies to protect biodiversity of plants and animals. It also allows us to engage with plant breeders to optimize pollinator attraction and ensure crop security.
Current projects include:
Petal epidermal morphology
The epidermis of the petal is the first point of contact for the pollinator, and provides visual, tactile, temperature and scent cues. We are exploring how petal epidermal cell morphology evolves within plant families, and whether it can be optimized to enhance crop pollination.
Structural colour in plants
Most plant colour is produced by pigments, but some particularly intense or iridescent colours are produced by periodic ordering of nanoscale structures. We are investigating how and why plants produce these structural colours.
Petal spot development
Spots on the petal can attract pollinators in a variety of ways, including by mimicking other insects. We are exploring how petal spots develop and what the genetic basis of their variation is.
