“…Possible oxidative damage induced by G-containing herbicides has been already postulated (Beuret et al, 2005;Gehin et al, 2005;Pieniazek et al, 2004;Richard et al, 2005). Considering these findings in the light of our previous investigations on nucleotide patterns, which suggested a redox imbalance in herbicide treated cells, we decided to investigate if herbicide treatments could affect the enzymatic activity of catalase and superoxide dismutase (SOD), two key enzymes in the cell response to oxidative stress.…”
