Sensory Transduction in Microorganisms
January 24-29, 2010
Ventura Beach Marriott
Ventura, CA
Chair:
Ann H. West

Vice Chair:
Caroline S. Harwood

This biennial Gordon Conference on Sensory Transduction in Microorganisms will attract researchers worldwide to the Ventura Beach Marriott in CA to present and discuss the very latest developments in signal transduction and cell motility in diverse prokaryotic and eukaryotic microorganisms. The Conference will feature traditional themes such as mechanisms that underlie cell movement, the molecular and structural basis for chemotaxis, multicellular behavior/development, and two-component signaling. Emerging or hot-topic research areas that also will be highlighted at this meeting include intracellular second messenger molecules such as cyclic nucleotides, spatial localization of signaling components, cell-cell communication, pathogenesis, and computational or global approaches to understanding signaling circuitry. Invited speakers will include both established and new investigators. In addition, some poster presenters will be selected for short talks. Participants will enjoy not only the collegial atmosphere of this Conference, but also bright sunshine and walks on the beach that provide valuable opportunities for engaging in scientific discourse and promoting interdisciplinary collaborations.
