应用
尾孢菌素（C29H26O10）是一种从香蕉病原体培养物中分离出来的红色色素。它已被用于研究野油菜黄单胞菌百日菊致病变种（Bacterium Xanthomonas campestris pv. Zinniae ）等物种的毒素生物降解。
生化/生理作用
头孢菌素是一种聚酮化合物植物毒素，可以被光激活，并在激活状态下与氧气反应生成有毒氧物种，例如单线态氧（O2）和超氧化物（O2-）。活性氧的产生导致植物细胞膜中脂质的过氧化。
据报道，光诱导的聚酮化合物植物毒素在光催化下会产生单线态氧。

Plant pathogens from the genus Cercospora produce cercosporin, a photoactivated fungal toxin that generates toxic reactive oxygen species. Mechanisms governing toxin auto-resistance in Cercospora spp. are poorly understood. In this work, suppressive subtractive hybridization was used to identify genes differentially

DNA photolyases harvest light energy to repair genomic lesions induced by UV irradiation, whereas cryptochromes, presumptive descendants of 6-4 DNA photolyases, have evolved in plants and animals as blue-light photoreceptors that function exclusively in signal transduction. Orthologs of 6-4 photolyases

The polyketide synthase CTB1 is demonstrated to catalyze pyrone formation thereby expanding the known biosynthetic repertoire of thioesterase domains in iterative, non-reducing polyketide synthases.

The malaria parasite Plasmodium falciparum is able to synthesize de novo PLP (pyridoxal 5'-phosphate), the active form of vitamin B6. In the present study, we have shown that the de novo synthesized PLP is used by the parasite to detoxify

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
