“…1). In the present study, the reduction in chlorophyll concentration observed indicates oxidative damage induced by Pb exposure, possibly due to the inhibition of aminolevulinic acid dehydratase, an important enzyme in chlorophyll biosynthesis (Pereira et al, 2006). Similar to our observations, the chlorophyll level was reduce in wheat treated with Ni (Gajewska and Sktodowska, 2007), in maize treated with Cd ( Jain et al, 2007), in radish treated with Pb (Gopal and Rizvi, 2008) and in cotyledons cucumber treated with Aluminum (Perira et al, 2010).…”

Oxidative stress was induced by lead acetate (Pb) in Raphanus sativus seedlings grown in a hydroponic system using sand as substrate. Thirty day old acclimated seeds were treated for 7 days with five Pb levels (0 as control, 100, 200, 500 and 1000 mg l -1 ). Parameters such as growth, oxidative damage markers (lipid peroxidation, protein oxidation and hydrogen peroxide contents) and enzymatic activities of catalase (CAT) and peroxidase (POD) were investigated. Lead concentration in plant tissues increased with increasing of Pb levels. Shoot fresh weight, chlorophyll and carotenoid concentration were significantly decreased at 100 mg l -1 Pb. Lipid peroxidation, protein oxidation and H 2 O 2 levels were increased at 500 and 1000 mg l -1 Pb compared to control treatment, in shoots. Peroxidase activity showed a straight correlation with H 2 O 2 concentration, whereas CAT activity decreased only in shoots. These changes in enzymatic and non-enzymatic antioxidants showed that the Pb exposition had a significant disturbance on Raphanus sativus plantlets and affect the biochemical and physiological processes.

“…In fact, it has been reported that usually the inhibition of root elongation is the most sensitive parameter of Cd toxicity (Guo & Marschner 1995;Pavlovkin et al 2006). Data from our research group have demonstrated that others metals such as mercury (Hg) and aluminium impair shoot length and root elongation of cucumber (Cargnelutti et al 2006;Pereira et al 2006).…”

“…Cucumber is an important crop plant which was selected as a test plant species due to its sensitivity to a wide range of contaminants (Pereira et al 2006;Tabaldi et al 2007) and also due to the insufficient information available on Cd toxicity in this species. In order to get more information on the mechanisms involved in the plant tolerance to this metal, we verified the effects of Cd on plant growth, histology of the roots, chlorophyll a, chlorophyll b, total chlorophyll and carotenoids contents, δ-aminolevulinic acid dehydratase and acid phosphatase activities, soluble phosphorus (Pi) and Ca, K, Mg, Fe, Zn, and Na contents.…”

In this study, the effects of cadmium chloride (CdCl2) on plant growth, histology of roots, photosynthetic pigments content, δ-aminolevulinic acid dehydratase (ALA-D; E.C. 4.2.1.24) and acid phosphatase activities (AP; E.C. 3.1.3.2), soluble phosphorus (Pi) measurement and mineral nutrients content in cucumber seedlings (Cucumis sativus L.) were investigated. Cucumber seedlings were grown in vitro in an agar-solidified substrate containing four CdCl2 treatments (0, 100, 400, and 1000 µM) for ten days. Cd was readily absorbed by seedlings and its content was greater in the roots than in the shoot. Cd reduced shoot and root length, and fresh and dry biomass of seedlings. Inhibition of root cell elongation in Cd-treated seedlings was observed by the increase of the mean radial size of cells belonging to three zones of the root tip. The highest level of Cd reduced in a similar manner chlorophyll a, chlorophyll b and total chlorophyll contents. Increasing concentrations of Cd resulted in a linear decrease in carotenoids levels of cotyledons. Interestingly, the ALA-D activity in cotyledons was inhibited only at the highest level of Cd. Root and shoot AP activities were, respectively, activated and inhibited at all CdCl2 concentrations. Root Pi concentration was increased in all Cd treatments and it was not altered in the shoot tissues. Moreover, in general, the nutrient contents were increased in the root and decreased in the shoot. Therefore, we suggest that Cd affects negatively growth, photosynthetic pigments, ALA-D and AP activities and partition of mineral nutrients in cucumber seedlings.

“…Similar results of Al toxicity on photosynthetic pigments have been reported in Citrus (Jiang et al, 2009) and Brassica napus (Zahra et al, 2015). Pereira et al, (2006) showed that, Al caused decrease in Chl synthesis by inhibiting the activity of aminolevulinic acid (ALA) dehydratase enzyme responsible for the formation of monopyrroleporphobilonogen, which is a part of the Chlmolecule as well as the cytochromes and also impaired plant growth. Vetorello et al, (2005) also reported that Al toxicity resulted in declined chlorophyll content due to cellular and ultrastructural modifications of leaves, reduction of stomatal opening, decreased photosynthetic activity, chlorosis and leaf necrosis.…”
