Outline of Final Research Achievements

Phytophagous insects are highly adapted to plant secondary metabolites, whereas plants rely on insect pollinators often effectively guiding them by specific floral fragrances (synomones) in the mutualistic interactions. My research aims to understand the molecular basis of coevolutionary pathway in both pollinator insects (chemoreceptors to perceive floral volatiles) and flowering plants (floral synomone biosynthesis), particularly focusing on pollination syndromes between (1) Bactrocera fruit flies (Tephritidae:Diptera) and Bulbophyllum fruit fly orchids (Orchidacea), and (2) Desmometopa flies (Milichiidae:Diptera) and pipevine flowers (Aristolochia:Aristolochiaceae).
