Induction of Enzymes of Phytoalexin Synthesis in Soybean Cells by Fungal Elicitor
Higher plants have aquired effective defence mechanisms during evolution, which secure their survival in the presence of a large variety of infective microorganisms. Resistance mechanisms of plants are expressed at different levels in host-parasite interactions including preformed physical and chemical defence barriers as well as defences triggered by the invader . One type of active response of plants to attempted infection is the production of low molecular weight antimicrobial compounds called phytoalexins. Considerable evidence supports the view that the phytoalexin response is one mechanism by which plants resist diseases [6, 12, 14, 21].
