“…CP-13rif inoculation, linseed Cd content was enhanced with increasing levels of Cd stress (Table 3). In linseed, Cd treatment resulted in a high deposition of Cd in the cell walls of root cells (Redjala et al 2009) and increased levels of apoplastic Cd ultimately caused an even higher plant-Cd content (Sterckeman et al 2011). In the present investigation, the Cd content of Serratia sp.…”

Aims The current study was aimed to evaluate the beneficial effects and bioremediation potential of a Cd‐tolerant bacterial strain, Serratia sp. CP‐13, on the physiological and biochemical functions of Linum usitatissimum L., under Cd stress. Methods and Results The bacterial strain was isolated from the wastewater collection point of Chakera, Faisalabad, Pakistan, as this place contains industrial wastewater of the Faisalabad region. The Serratia sp. CP‐13, identified through 16S rRNA gene sequence analysis, exhibited a significant phyto‐beneficial potential in terms of in vitro inorganic phosphate solubilization, indole‐3‐acetic acid production and 1‐aminocyclopropane‐1‐carboxylic acid deaminase activity. Effects of Serratia sp. CP‐13 inoculation on L. usitatissimum were evaluated by growing the plants in CdCl2 (0, 5 or 10 mg kg−1 dry soil)‐spiked soil. Without inoculation of Serratia sp. CP‐13, Cd stress significantly reduced the plant biomass as well as the quantity of proteins and photosynthetic pigments due to enhanced H2O2, malondialdehyde (MDA) contents and impaired nutrient homeostasis. Subsequently, Serratia sp. CP‐13 increased the plant fresh and dry biomass, plant antioxidation capacity, whereas it decreased the lipid peroxidation under Cd stress. In parallel, Serratia sp. inoculation assisted the Cd‐stressed plants to maintain an optimum level of nutrients (K, Ca, P, Mg, Fe and Mn). Conclusions The isolated bacterial strain (Serratia sp. CP‐13) when applied to Cd‐stressed L. usitatissimum inhibited the Cd uptake, reduced Cd‐induced lipid peroxidation, maintained the optimum level of nutrients and thereby, enhanced L. usitatissimum growth. The analysis of bio‐concentration and translocation factor revealed that L. usitatissimum with Serratia sp. CP‐13 inoculation sequestered Cd in plant rhizospheric zone. Significance and Impact of the Study Serratia sp. CP‐13 inoculation is a potential candidate for the development of low Cd‐accumulating linseed and could be used for phytostabilization of Cd‐contaminated rhizosphere/soil colloids.

Cadmium uptake in Elodea canadensis leaves and its interference with extra‐ and intra‐cellular pH

This study investigated cadmium (Cd) uptake in Elodea canadensis shoots under different photosynthetic conditions, and its effects on internal (cytosolic) and external pH. The plants were grown under photosynthetic (light) or non-photosynthetic (dark or in the presence of a photosynthetic inhibitor) conditions in the presence or absence of CdCl2 (0.5 μm) in a medium with a starting pH of 5.0. The pH-sensitive dye BCECF-AM was used to monitor cytosolic pH changes in the leaves. Cadmium uptake in protoplasts and leaves was detected with a Cd-specific fluorescent dye, Leadmium Green AM, and with atomic absorption spectrophotometry. During cultivation for 3 days without Cd, shoots of E. canadensis increased the pH of the surrounding water, irrespective of the photosynthetic conditions. This medium alkalisation was higher in the presence of CdCl2 . Moreover, the presence of Cd also increased the cation exchange capacity of the shoots. The total Cd uptake by E. canadensis shoots was independent of photosynthetic conditions. Protoplasts from plants exposed to 0.5 μm CdCl2 for 3 days did not exhibit significant change in cytosolic [Cd(2+)] or pH. However, exposure to CdCl2 for 7 days resulted in increased cytosolic [Cd(2+) ] as well as pH. The results suggest that E. canadensis subjected to a low CdCl2 concentration initially sequesters Cd into the apoplasm, but under prolonged exposure, Cd is transported into the cytosol and subsequently alters cytosolic pH. In contrast, addition of 10-50 μm CdCl2 directly to protoplasts resulted in immediate uptake of Cd into the cytosol.

“…This appears to be the case for lead, 13 copper 19 and vanadium. 20 However, other equally important elements such as cadmium 21 and mercury 22 appear readily mobile subsequent to root uptake. From the above it is clear that the factors which regulate the incidence and quantity of root-absorbed heavy metals in the lumina of xylem elements require further investigation.…”
