Biochem/physiol Actions
A light-induced polyketide phytotoxin reported to produce singlet oxygen when photoactivated.
Cercosporin, a polyketide phytotoxin, is activated by light and in the activated state, reacts with oxygen to produce toxic oxygen species such as singlet oxygen (O₂) and superoxide (O₂⁻). Production of reactive oxygen species leads to peroxidation of lipids in the plant cell membranes.
