Evolution of floral secretory structures involved in plant-pollinator interactions in the Tigridieae tribe (Iridaceae).
Within Iridaceae, some species, mainly in the Tigridieae tribe, have oil-produicing flowers. These oils, secreted by structures called elaiophores, represent a third resource for the pollinators in addition to nectar and pollen. My thesis project involves:
– Clarify phylogenetic relationships within the tribe with expanded taxonomic sampling, chloroplast genomes and AFLP data.
– Reconstruct ancestral states of floral coloration patterns and elaiophores.
– Characterize the morphogenesis of these secretory structures.
