DETAILS

Description (English)

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.
Application
Cercosporin (C29H26O10) is a red pigment that has been isolated from cultures of a banana pathogen 1. It has been used to study toxin biodegredation in species such as Bacterium Xanthomonas campestris pv. Zinniae 2.
