Photochemical dimerization of wasalexins in UV-irradiated Thellungiella halophila and in vitro generates unique cruciferous phytoalexins
Sulfur compounds such as phytoalexins
and glucosinolates, may be important enhancers of the protection of plants to adverse agents such as arthropods and plant pathogens (Dubuis 2004; Hell and Kruse 2007, Bohinc et al.
In the hypersensitive response (HR), plant produces antimicrobial agents, called phytoalexins
, and PR proteins (pathogenesis related proteins) in the infected tissues through the usual response mechanism with an Avr-R interaction.

They contain phytoalexins

At phytotoxic levels, protox inhibitors such as acifluorfen induce phenylalanine ammonia-lease, which increases phytoalexins
and stress metabolites in plants (e.
Kauralexins and zealexins, members of a larger family of plant-defense compounds known as "terpenoid phytoalexins
," are also partly triggered by insect chewing--with Ostrinia nubilalis, the European corn borer, among species that find them distasteful.
