“…Shoot transport of Cd was specifically reduced in Jena, while Zn transport was not restricted. Similar results have been reported in soil-grown T. arvense (Ozturk et al 2003). Comparison between two near isogenic wheat lines also found differential Cd translocation to shoots; this mechanism was specific for Cd and not for Zn (Hart et al 2006).…”

“…Thlaspi arvense has been reported as a Cd-sensitive plant species and several authors have used this weed in comparison studies to reveal the hyperaccumulation traits of closely related hyperaccumulating species like Noccaea caerulescens (former Thlaspi caerulescens) or ⎯⎯⎯⎯ T. praecox (Schat et al 2000, Ozturk et al 2003, Hammond et al 2006, Tolrà et al 2006, Zelko et al 2008. However, to our best knowledge differences in Cd-tolerance among T. arvense accessions from different habitats have not previously been reported.…”

Differences in Cd accumulation and Cd tolerance between Thlaspi arvense ecotype Aigues Vives (AV) from a commercial grower in South France and ecotype Jena collected in the polluted urban area of Jena (Germany) were reported here. Ecotype Jena exhibited considerable Cd-tolerance. Shoot and root masses were unaffected and root elongation was even enhanced by exposure to 50 µM Cd. In contrast, growth of ecotype AV was severely affected by this Cd treatment. Ecotype Jena was much more efficient in excluding Cd from both roots and shoots than ecotype AV. Despite the efficient restriction of Cd transport from roots to shoots in Jena, this ecotype maintained high root to shoot transport of Zn and Fe under Cd exposure. Cd supply strongly decreased the activities of antioxidant enzymes in AV, while in the Cd resistant Jena these activities either remained unaffected (SOD, APX) or were increased (CAT) by Cd supply. In conclusion, naturally selected Cd-tolerance in Thlaspi arvense is due to efficient Cd exclusion. The mechanisms underlying exclusion of Cd from the shoots seem Cd-specific yet they did not affect the homeostasis of Fe and Zn in the shoots.Additional key words: ascorbate peroxidase, catalase, iron, superoxide dismutase, zinc.

“…Shah et al [14] stated that the increased activity of antioxidative enzymes in metal exposed plants appears to serve as an important component of antioxidant defense mechanism of plants to combat metalinduced oxidative injury. Several researchers [15][16][17][18] have reported in different plant species the involvement of glutathione and ascorbic acid in the tolerance of plants to Cd phytotoxicity. Seregin and Ivanov [19] stated that the decline in net photosynthetic rate in Cd exposed plants results from the distorted chloroplast ultrastructure, restrained synthesis of chlorophylls, plastoquinone, and carotenoids, disturbed electron transport, and inhibited activities of Calvin cycle enzymes and carbon dioxide deficiency in the cells.…”

Lettuce varieties Bombilasta BBL and Italian 167 were treated with different concentrations of cadmium (0, 3, 6, 9, and 12 mg/L) in a nutrient film technique (NFT) system to study its toxicity on phytochemicals and nutrient elements. Antioxidants analysis which employed DPPH and FRAP, flavonoids, phenolic, vitamin C, malondialdehyde (MDA), and proline indicated significant effects of Cd treatment on the varieties tested. Different concentration levels of Cd lead to positive interactions in FRAP, phenolic, and MDA but no significant effect in flavonoids, vitamin C, and proline. Contents of macro-and microelements in the varieties were significantly affected with increase in the toxicity levels of Cd in all nutrient elements tested with interactions exhibited for iron, manganese, and zinc.
