Applicazioni

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 .

Azioni biochim/fisiol

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.
A light-induced polyketide phytotoxin reported to produce singlet oxygen when photoactivated.

Altre note

Keep container tightly closed in a dry and well-ventilated place.

Antioxidant defense systems are a prominent element in plant responses to environmental stress. Activated oxygen species have themselves been implicated as both a part of the plant's defense against pathogen attack as well as the phytotoxic component of photosensitizing fungal
