Quercetin feeding protects plants against oxidative stress

Flavonoids are a complex group of plant-made phenolic Background: compounds that are considered of high nutraceutical value. Their beneficial impacts on human health relate predominantly to their capacity to serve as antioxidants, thus protecting cells against the damaging impact of reactive oxygen species. Recent studies have also pointed at an essential role for flavonoids as antioxidants in plants. Here we show that the flavonoid quercetin, which is known to protect Results: human cells from oxidative stress, has the same effect on plant cells. Under oxidative stress conditions, Arabidopsis plants grown on quercetin-supplemented media grew better than controls and contained less oxidized proteins. This protection was also observed in the dicot Nicotiana and the aquatic monocot . tabacum Lemna gibba Quercetin can be used as a general antioxidant stress protectant Conclusion: for plants. Jan A.
