Elsinochrome C is a perylenequinone pigment produced by many Elsinoe fungal species, structurally related to cercosporin. Elsinochrome C exists in solution in approximately equal proportions of the tauromers, C1 and C2. Elsinochrome is a light-activated, nonhost-selective phytotoxin that can damage cell membranes and induce electrolyte leakage. Elsinochromes function as photosensitizing compounds that produce singlet oxygen and superoxide, thereby exerting toxicity to plant cells.
