Abstract
Plants interact with many other living things around them. Flowers produce a variety of colors in petals and a bouquet of scents to attract bees, butterflies, and moths for pollination. Plants also produce toxic metabolites against herbivore attacks and emit SOS signals for calling herbivore’s enemy. Thus, the diverse messages of the plant are transmitted through chemicals. We have examined the function of metabolites and genes to answer ecological questions derived from natural observation. In this time, I will talk about how the wild tobacco, Nicotiana attenuata plants defend themselves against a stem boring insect, Trichobaris mucorea. Next, I will discuss diurnal rhythms in the flowers of N.attenuata flower: opening/closing, vertical movement, and scent emission –all these actions can be viewed in the light of how best the flower can attract certain pollinators at various times. Finally, I will briefly introduce a collaboration project between a biologist and an engineer to see the flower volatile emission.
