Seedlings were grown in vitro in an agar-solidified substrate containing four Cd levels as CdCl2 (0, 100, 400, and 1000 \u00b5mol L-1) for 10 d. The lowest Cd level decreased the malondialdehyde concentration. Electrolyte leakage increased only at 1000 \u00b5mol Cd L-1, whereas protein oxidation and total soluble protein content were enhanced at 400 and 1000 \u00b5mol Cd L-1. Activity of APX was inhibited while the activities of CAT and SOD were increased at all Cd concentrations. Ascorbic acid was enhanced at 400 and 1000 \u00b5mol Cd L-1 whereas non-protein thiol groups were increased at all Cd supplies. The results evidence the importance of the enzymatic and non-enzymatic antioxidant system in response to cadmium toxicity in cucumber seedlings.<\/jats:p>","DOI":"10.1590\/s1677-04202007000300006","type":"journal-article","created":{"date-parts":[[2008,1,18]],"date-time":"2008-01-18T08:18:30Z","timestamp":1200644310000},"page":"223-232","source":"Crossref","is-referenced-by-count":60,"title":["Cadmium toxicity causes oxidative stress and induces response of the antioxidant system in cucumber seedlings"],"prefix":"10.1590","volume":"19","author":[{"given":"Jamile F.","family":"Gon\u00e7alves","sequence":"first","affiliation":[]},{"given":"Alexssandro G.","family":"Becker","sequence":"additional","affiliation":[]},{"given":"Denise","family":"Cargnelutti","sequence":"additional","affiliation":[]},{"given":"Luciane A.","family":"Tabaldi","sequence":"additional","affiliation":[]},{"given":"Luciane B.","family":"Pereira","sequence":"additional","affiliation":[]},{"given":"Vanessa","family":"Battisti","sequence":"additional","affiliation":[]},{"given":"Ros\u00e9lia M.","family":"Spanevello","sequence":"additional","affiliation":[]},{"given":"Vera M.","family":"Morsch","sequence":"additional","affiliation":[]},{"given":"Fernando T.","family":"Nicoloso","sequence":"additional","affiliation":[]},{"given":"Maria R.C.","family":"Schetinger","sequence":"additional","affiliation":[]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"121","DOI":"10.1016\/S0076-6879(84)05016-3","article-title":"Catalase in vitro","volume":"105","author":"Aebi H","year":"1984","journal-title":"Methods Enzymol.","ISSN":"https:\/\/id.crossref.org\/issn\/0076-6879","issn-type":"print"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1590\/S1677-04202005000100002","article-title":"Cadmium-zinc interactions in a hydroponic system using Ceratophyllum demersum L.: adaptative ecophysiology, biochemistry and molecular toxicology","volume":"17","author":"Arvind P","year":"2005","journal-title":"Braz.
