Meeting Description

While the first two Gordon Conferences in this series were devoted to consideration of floral volatiles, our 2007 meeting will be the first to expand to cover the entire gamut of plant volatiles, from chemistry and biochemistry to physiology and ecology. The field of plant volatiles has experienced a major acceleration in the rate of discovery due to the development of new techniques in metabolomics and genomics. A recent special issue of Science (10th February 2006, vol. 311) on the theme of plant volatiles contained a number of articles about the discovery of new plant volatiles in exotic plants, the evolution of the enzymes responsible for the synthesis of new volatile compounds, the ecological roles of plant volatiles in enhancing plant fitness, and the dietary properties (for humans) of plant volatiles. This conference will discuss new discoveries and approaches in the following areas:

  • Physiological and ecological roles of plant volatiles produced in vegetative tissues, including plant-herbivore interactions.
  • Physiological and ecological roles of floral volatiles in reproduction, including plant-pollinator interactions.
  • Techniques and methodologies for studying plant volatiles.
  • Chemistry and biochemistry of plant volatiles.
  • Roles of plant volatiles in human affairs.

Oral presentations will be complemented by poster sessions scheduled for the afternoons. All attendees are encouraged to contribute a poster.
