Application
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。
Biochem/physiol Actions
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

A red pigment produced by a Mexican isolate of Cercospora piaropi (waterhyacinth pathogen) has been isolated and identified as cercosporin. The kinetic of cercosporin production in culture media during dark/light regimes was evaluated. When C. piaropi was cultivated in continuous

An evaluation of the potential hazards associated with mutagenicity and acute toxicity of a mycoherbicide formulation based on the fungal pathogen Cercospora piaropi was performed. Neither the mycoherbicide nor any of its components were mutagenic to Salmonella typhimurium TA98 and
