UV-B radiation: “When does the stressor cause stress?”

The UV-B induced increase in antioxidative defenses is further demonstrated by increases in both the reduction state and pool-size for antioxidants such as ascorbate, glutathione, xanthophylls, and tocopherol (Jansen et al., 2008). [...]numerous studies have reported upregulation of enzymatic antiox...

Description
Summary:The UV-B induced increase in antioxidative defenses is further demonstrated by increases in both the reduction state and pool-size for antioxidants such as ascorbate, glutathione, xanthophylls, and tocopherol (Jansen et al., 2008). [...]numerous studies have reported upregulation of enzymatic antioxidant activities, including Cu or Zn superoxide dismutase (SOD), ascorbate peroxidase (APX), dehydroascorbate reductase (DHR), glutathione peroxidase (GPX), glutathione reductase (GR) and catalase activities (Hideg et al., 2006; Agrawal and Rathore, 2007; Xu et al., 2008). [...]the study of oxidative UV-B stress has clear (but under explored) links to evolutionary plant ecology. 3) UV-B as an exploitable regulator in horticulture UV-B can induce a range of specific plant responses, some of which are particularly desirable from a horticultural perspective.
