This is an exciting period in plant biology as many disciplines, such as genetics and biochemistry, are merging to provide a more detailed understanding of plant growth and development. The purpose of this meeting was to provide a sampling of some of this exciting work in the area of cellular communication and signal transduction. R. M.
