Increased expression of Fe-chelatase leads to increased metabolic flux into heme and confers protection against photodynamically induced oxidative stress.
Plant Mol. Biol. 86(3) , 271-87, (2014) Fe-chelatase (FeCh, EC 4.99.1.1) inserts Fe(2+) into protoporphyrin IX (Proto IX) to form heme, which influences the flux through the tetrapyrrole biosynthetic pathway as well as fundamental cellular processes. In transgenic rice (Oryza sativa), the ectopic e... |

Photochemistry and photoinduced toxicity of acifluorfen, a diphenyl-ether herbicide.
J. Environ. Qual. 31(1) , 268-74, (2002) Photochemistry studies can be helpful in assessing the environmental fate of chemicals. Photochemical reactions lead to the formation of by-products that can exhibit different toxicological properties from the original compound. For this reason the photochemi... |

Photochemical transformation of acifluorfen under laboratory and natural conditions.
Pest Manag. Sci. 57(4) , 372-9, (2001) Acifluorfen was irradiated in pure water at various excitation wavelengths and pH values. Numerous photoproducts were obtained which were identified by [1H]NMR and/or HPLC-MS/MS. The main reaction pathways were photo-decarboxylation, photo-cleavage of the eth... |

A continuous fluorimetric assay for protoporphyrinogen oxidase by monitoring porphyrin accumulation.
Anal. Biochem. 344(1) , 115-21, (2005) A continuous spectrofluorimetric assay for protoporphyrinogen oxidase (PPO, EC 1.3.3.4) activity has been developed using a 96-well plate reader. Protoporphyrinogen IX, the tetrapyrrole substrate, is a colorless nonfluorescent compound. The evolution of the f... |

Impairment of the photosynthetic apparatus by oxidative stress induced by photosensitization reaction of protoporphyrin IX.
Biochim. Biophys. Acta 1767(6) , 860-8, (2007) Treatment with the herbicide acifluorfen-sodium (AF-Na), an inhibitor of protoporphyrinogen oxidase, caused an accumulation of protoporphyrin IX (Proto IX) , light-induced necrotic spots on the cucumber cotyledon within 12-24 h, and photobleaching after 48-72... |

The analysis of the ChlI 1 and ChlI 2 genes using acifluorfen-resistant mutant of Arabidopsis thaliana.
Planta 225(4) , 935-43, (2007) One of the key regulatory enzymes of the chlorophyll biosynthesis pathway is magnesium (Mg) chelatase, consisting of three different subunits CHLI, CHLD and CHLH. While CHLH and CHLD are encoded by a single gene each in Arabidopsis, CHLI is encoded by two hom... |

An Arabidopsis mutant that is resistant to the protoporphyrinogen oxidase inhibitor acifluorfen shows regulatory changes in tetrapyrrole biosynthesis.
Mol. Genet. Genomics 273(4) , 311-8, (2005) Several Arabidopsis mutants of the ecotype Dijon were isolated that show resistance to the herbicide acifluorfen, which inactivates protoporphyrinogen oxidase (PPOX), an enzyme of tetrapyrrole biosynthesis. This enzyme provides protoporphyrin for both Mg chel... |
