摘要：

Phytoalexins are low-molecular-weight antimicrobial compounds that accumulate in plants as a result of infection or stress. The rapidity and extent of their accumulation is determined by their release or the release of immediate precursors from conjugates and/or de novo synthesis, as well as detoxification as a result of plant or microbial enzymes. The rapidity of phytoalexin accumulation is associated with resistance in plants to diseases caused by fungi and bacteria, although the genetic information for phytoalexin synthesis is found in susceptible and resistant plants. Phytoalexins are only one component of the complex mechanisms for disease resistance in plants. This review considers the contribution of phytoalexins to disease resistance and evaluates molecular and nonmolecular strategies for their biosynthesis as potential technologies for disease control.
