“…Early studies indicated that isoproturon was designed to block the photosystem electron transport in thylakoids at the photosystem II by binding specifically to the quinone site on the D1 protein (dopamine receptor) of the membrane [14,15]. Recent studies have shown that IPU could also be accumulated by other non-target plants and exert detrimental effects on these plants [9,[16][17][18].…”

“…In addition, the growth rates of the ciliate (Tetrahymena pyriformis) and common earthworm (Lumbricus terrestris) were inhibited at 700 g/L or 1.4 g IPU/kg soil, respectively, whereas other Brought to you by | Kungliga Tekniska Högskolan Authenticated Download Date | 7/1/15 10:49 PM of 5 or 50 μm IPU (p < 0.01) ( Figure 5). The GR activity of S. cerevisiae is probably involved in the detoxification of IPU, ensuring the efficient recycling of glutathione to protect cells against phenylurea herbicide, as described in wheat leaves (Triticum aestivum) [28].…”

Triazines and phenylureas, mainly used in agricultural applications for the selective control of germinating grasses and broad-leaved weeds, are often found in contaminated groundwater, surface water and the effluents of wastewater treatment plants. The toxicity of these herbicides in eukaryotic cells is poorly understood. Saccharomyces cerevisiae is a promising unicellular organism for the toxicological evaluation of xenobiotics because its metabolism is similar to that of higher-level organisms. Consequently, the aim of this study was to compare the effects of three herbicides on yeast-cell growth and the glutathione cycle. Saccharomyces cerevisiae grown in the presence of 5 or 50 μM atrazine, diuron or isoproturon were compared with control cells grown in a rich medium. The results show that the glutathione-dependent buffer capacity decreased significantly in S. cerevisiae grown in the presence of both levels of any of the three herbicides, except in cells exposed to 50 μM isoproturon. In addition, chlorine herbicides inhibited cell growth, probably due to a decrease in antioxidant power and glutathione reductase activity. Isoproturon at 50 μM induced yeast-cell growth, increasing the buffer capacity mediated by glutathione as well as glutathione reductase and glutathione peroxidase activities of UE-ME3 strain. This strain may be useful in studies of isoproturon degradation.

For example, salicylic acid (SA), a regulator of plant response to various environmental stresses (Yang et al, 2003;Liang et al, 2012), has been reported to improve plant resistance to herbicide napropamide toxicity in rapeseed (Brassica napus) (Cui et al, 2010). Cytochrome P450s are known to be involved in detoxification of xenobiotics in the phase I metabolism in plants (Siminszky, 2006;Zhang et al, 2014;Kebeish et al, 2014).…”
