title: Determination of genotoxic effects of fipronil in Vicia faba using random amplified polymorphic DNA analysis.
abstract: This study was undertaken to appreciate genotoxic potential of fipronil herbicides in the roots of Vicia faba seedlings. Fipronil was clearly dose dependent on root growth inhibitors, total soluble protein, and random amplified polymorphic DNA (RAPD) assays. Increase in concentration of fipronil resulted in decreased amount of root length and increased level of protein. For the RAPD analyses, 15 RAPD primers were found to produce unique polymorphic band patterns and were subsequently used to produce a total of 110 bands of 45-1250 bp. Each primer generated 4-11 RAPD bands across 15 primers. The changes occurring in RAPD profiles following fipronil treatment included variation becoming evident as disappearance and/or appearance of DNA bands compared with the normal seedlings. These results indicated that genomic template stability was significantly affected at the above fipronil concentration. This study further confirmed that the RAPD assays are useful in determining potential genotoxicity of fipronil.
