As ROS have the potential to cause oxidative damage by reacting with biomolecules, research on ROS has concentrated on the oxidative damage that results from exposure to environmental stresses and on the role of ROS in defence against pathogens. However, more recently, it has become apparent that ROS also have important roles as signalling molecules. A complex network of enzymatic and small molecule antioxidants controls the concentration of ROS and repairs oxidative damage, and research is revealing t 410 0$aBiological Sciences Series 606 $aAntioxidants$xPhysiological effect 606 $aActive oxygen$xPhysiological effect 606 $aPlants$xMetabolism 608 $aElectronic books. 615 0$aAntioxidants$xPhysiological effect. 615 0$aActive oxygen$xPhysiological effect. 615 0$aPlants$xMetabolism. 676 $a572.42 676 $a572/.42 701 $aSmirnoff$b N$0990662 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910143294103321 996 $aAntioxidants and reactive oxygen species in plants$92266776 997 $aUNINA
