Signal Perception in Plants: Hepta-ß-Glucoside Elicitor Binding Proteins in Soybean
Living organisms utilize a large number of signal molecules to regulate their growth and development. Furthermore, the cells that make up an organism have evolved complex and diverse mechanisms for perceiving and responding to signal molecules originating not only from within the organism, but also from the external environment. Biochemical analysis of the interactions between plants and microbes has contributed to a greater understanding of the molecular basis for signal perception and transduction in plant cells (for recent reviews, see [1–3]). Research in this area has led to the discovery of new classes of signal molecules and provided useful model systems for molecular studies on signal perception, signal transduction, and gene regulation in plants. This article will give an overview of our studies of one plant signal transduction system, the induction of phytoalexin accumulation by oligoglucoside elicitors. Our research to date has focussed on the first stage of this signal transduction system, the specific recognition by plant receptors of molecules (elicitors) that induce phytoalexin accumulation.
