Phytoalexins play a significant role in the defense response of plants. The
se secondary metabolites, which are synthesized de novo in response to dive
rse forms of stress, including fungal infection, are part of the plants' ch
emical and biochemical defense mechanisms. Phytoalexins from crucifers are
structurally and biogenetically related, but display significantly differen
t biological activities. Here, we review work reporting: the chemical struc
tures, synthesis, biosynthesis and metabolism of cruciferous phytoalexins,
as well as their biological activity towards different microorganisms. (C)
