Accumulation of Protoporphyrin IX in the Presence of Peroxidizing Herbicides
Peroxidizing herbicides were assayed for their capacity to accumulate tetrapyrrole-like compounds in the liquid culture medium when growing the xanthophycean alga Bumilleriopsis filiformis. W e have isolated and purified this compound by H P L C . For identification optical, fluorescence, N M R and mass spectroscopy were employed. All these techniques showed that the accumulation product is pro...

متن کاملA Quantum Chemical Study of “Light-Dependent Herbicides”
Com m on structural features were investigated for “light-dependent herbicides” (LD H s, also called peroxidizing or photobleaching herbicides). Q uantum chemical calculations of 143 herbicidal com pounds revealed that LU M O levels o f L D H s were sim ilar and strikingly low. Using the LUM O position as an anchor, presum ably know n structure-activity relation ships could be explained. Overa...
متن کاملA Non-Metabolic Model of Acifluorfen Activity
The para -nitro substituted diphenyl ether herbicides which cause rapid plant pigment photobleaching can be divided into two categories: 1. those that have a photosynthetic requirement for activity (e.g. oxyfluorfen) and 2. those that have no apparent metabolic requirement for activity (e.g. acifluorfen). A m odel is presented for the latter category, in which the diphenyl ether herbicide inter...
