Title: | Metal-Induced Oxidative Stress and Plant Mitochondria | Authors: | KEUNEN, Els REMANS, Tony BOHLER, Sacha VANGRONSVELD, Jaco CUYPERS, Ann |
Issue Date: | 2011 | Publisher: | MDPI AG | Source: | INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES, 12(10), p. 6894-6918 | Abstract: | A general status of oxidative stress in plants caused by exposure to elevated metal concentrations in the environment coincides with a constraint on mitochondrial electron transport, which enhances ROS accumulation at the mitochondrial level. As mitochondria are suggested to be involved in redox signaling under environmental stress conditions, mitochondrial ROS can initiate a signaling cascade mediating the overall stress response, i.e., damage versus adaptation. This review highlights our current understanding of metal-induced responses in plants, with focus on the production and detoxification of mitochondrial ROS. In addition, the potential involvement of retrograde signaling in these processes will be discussed. | Notes: | [Keunen, Els; Remans, Tony; Bohler, Sacha; Vangronsveld, Jaco; Cuypers, Ann] Hasselt Univ, Ctr Environm Sci, B-3590 Diepenbeek, Belgium. | Keywords: | toxic metals;oxidative stress;reactive oxygen species (ROS);plant mitochondria;oxidative damage;signaling | Document URI: | http://hdl.handle.net/1942/13002 | ISSN: | 1661-6596 | e-ISSN: | 1422-0067 | DOI: | 10.3390/ijms12106894 | ISI #: | 000296569600035 | Rights: | 2011 by the authors; licensee MDPI, Basel, Switzerland.
