Title: | Oxidative stress reactions induced in beans (Phaseolus vulgaris) following exposure to uranium | Authors: | VANDENHOVE, Hildegarde CUYPERS, Ann Van Hees, M. Koppen, G. Wannijn, J. |
Issue Date: | 2006 | Publisher: | Elsevier | Source: | PLANT PHYSIOLOGY AND BIOCHEMISTRY, 44(11-12). p. 795-805 | Abstract: | The present study aimed to analyze the biological effects induced by bioaccumulation of uranium in Phaseolus vulgaris. Ten-day-old seedlings were exposed to 0, 0.1, 1, 10, 100 and 1000 mu M U in diluted Hoagland solution. Following 1, 2, 4 and 7 days' exposure, plants were monitored for uranium uptake, biometric parameters, capacities of enzymes involved in the anti-oxidative defense mechanisms (GPOD, SPOD, GLUR, SOD, ICDH, G-6P-DH), glutathione (GSH) pool and DNA integrity. Uranium contents were up to 900-fold higher in roots (31-14,916 mg kg(-1) FW following 7 days' exposure to 0.1 and 1000 mu M U, respectively) as compared to primary leaves (1-16 mg kg(-1) FW following | Document URI: | http://hdl.handle.net/1942/1544 | ISSN: | 0981-9428 | e-ISSN: | 1873-2690 | DOI: | 10.1016/j.plaphy.2006.10.013 | ISI #: | 000243445700021 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2008 |
