ABSTRACT
Though the toxicity of phytoalexins is well documented, their mechanism of action on fungal cells is poorly understood. However, many fragmentary reports are available and it is possible to propose a mechanism of fungitoxic mode of action of the hydroxystilbenes. These compounds belong to the large family of plant phenolics from which numerous other phytoalexins are recognized. According to their basic common chemical structure, it is expected that all phenolics act on similar biochemical pathways and that their fungicidal mode of action is identical.
