Plant pathogenic fungi in eight genera produce light-activated perylenequinone toxins that are toxic to plants via the generation of activated oxygen species, particularly singlet oxygen. Studies on the cercosporin toxin produced by Cercospora species have documented an important role for this toxin in pathogenesis of host plants. Cercosporin-generated active oxygen species destroy the membrane...
TagRFP, a fluorescent protein capable of photosensitizing the production of singlet oxygen, was expressed in E. coli. Subsequent exposure to green light induced bacterial cell death in a light-dose dependent manner. It is demonstrated for the first time that intracellular singlet oxygen is sufficient to kill bacteria.
Singlet oxygen is believed to be the species destroying cancerous cells during PDT. An optically-based imaging device for monitoring singlet oxygen production in a tumor was developed and tested in-vivo. ©2008 Optical Society of America OCIS codes: (170.0110) Imaging systems; (170.5180) Photodynamic therapy
