Application

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

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.

Other Notes
