Session 1: Green leaf volatiles

Organized by Kenji Matsui (Yamaguchi University), Kazuhiko Matsuda (Kinki University)

Green leaf volatiles are ubiquitous in the plant kingdom. Based on long and detailed studies on green leaf volatiles conducted primarily in Japan, we now know that green leaf volatiles are key in ecosystems comprising plants, microbes, and animals, which will be discussed in this session.

Kenji Matsui (Yamaguchi University)
Green leaf volatiles: their formation and ecological relevance
Kazuhiko Matsuda (Kinki University)
Lessons from green odor/jasmonate-like natural products
Kazushige Touhara (University of Tokyo)
Green leaf volatiles and the specific olfactory receptors involved in chemoattractive behavior of silkworms

July 3 (Friday)
12:30-14:30
Session 2: Sociosexual communication in insects

Organized by Kazushige Touhara (University of Tokyo)

 Insects utilize volatile pheromones to establish their sociosexual communication. In this session, we focus on mechanisms underlying volatile/pheromone reception and on how the information is integrated in the brain, leading to a specific behavior. We also discuss about the significance of volatile compounds in ecological environment of various insect species.

Session 3: Pheromone communication in mammals

Organized by Hideto Kaba (Kochi University) and Kazushige Touhara (University of Tokyo)

 Chemosensory communication mediated by the olfactory system is crucial for mammals to acquire complex information of the second individual such as gender and family as well as physiological status. This session focuses on mammalian pheromones, and discusses about recent progresses in molecular biology, neurophysiology, and pharmacology of pheromone reception. Endocrinological and behavioral effects of pheromones will also be discussed.

Session 4: Odor psycophysics in human

Organized by Shuji Aou (Kyushu Tech. University)

 Humans got a big diversity of psycophysical effect by smell. While smell functions by mediating communications between insects or the other mammals, humans use smell to increase their QOL. This session focus on the psycophysical activity of volatile compounds on humans. Application of volatile compounds will be also discussed.

Session 5: Plant volatiles and defense

Organized by Junji Takabayashi (Kyoto University), Hisakazu Yamane (Tokyo University)

Plants defend themselves against herbivore and pathogen either directly or indirectly. Volatiles of plant origin may function as either direct defense weapons against pathogens, or information for natural enemies of herbivores indicating the presence of their victims (indirect defense). This session discuss how these volatiles are biosynthesized, and how they are used by other organisms belonging to different trophic levels.

Session 6: Plant-plant communication

Organized by Yoshiharu Fujii (NIAES), Kenji Matsui (Yamaguchi University)

Plants have abilities to perceive volatile compounds, and invoke defense responses to cope with future attack by pathogens and herbivores. This session discusses on how plants perceive the volatile compounds, how they activate the signaling pathways, and what is the outcome of this plant-plant interaction in the eco-systems.
