Medical Definition of Phytoalexin

1. Toxic compounds produced by higher plants in response to attack by pathogens and to other stresses. Sometimes referred to as plant antibiotics, but rather non-specific, having a general fungicidal and bacteriocidal action. Very much analogous to an antibody response as production is triggered by elicitors. Examples include: pisatin, phaseolin. (14 Oct 1997)
