“…2B). The responses of Zn in plants to Cd addition here is consistent with those of some hyperaccumulators, but opposite to responses of most non-hyperaccumulation crop plants showing inhibitory effect (Cataldo et al 1983, Hawf &Schmid 1967, Mohammad &Moheman 2010, Root et al 1975. The inhibitory effect is due to sharing some common transport sites and resulting in competition between Cd and Zn.…”

Many polluted sites are typically characterized by contamination with multiple heavy metals, drought, salinity, and nutrient deficiencies. Here, an Australian native succulent halophytic plant species, Carpobrotus rossii (Haw.) Schwantes (Aizoaceae) was investigated to assess its tolerance and phytoextraction potential of Cd, Zn, and the combination of Cd and Zn, when plants were grown in soils spiked with various concentrations of Cd (20-320 mg kg(-1) Cd), Zn (150-2,400 mg kg(-1) Zn) or Cd + Zn (20 + 150, 40 + 300, 80 + 600 mg kg(-1)). The concentration of Cd in plant parts followed the order of roots > stems > leaves, resulting in Cd translocation factor (TF, concentration ratio of shoots to roots) less than one. In contrast, the concentration of Zn was in order of leaves > stems > roots, with a Zn TF greater than one. However, the amount of Cd and Zn were distributed more in leaves than in stems or roots, which was attributed to higher biomass of leaves than stems or roots. The critical value that causes 10% shoot biomass reduction was 115 μg g(-1) for Cd and 1,300 μg g(-1) for Zn. The shoot Cd uptake per plant increased with increasing Cd addition while shoot Zn uptake peaked at 600 mg kg(-1) Zn addition. The combined addition of Cd and Zn reduced biomass production more than Cd or Zn alone and significantly increased Cd concentration, but did not affect Zn concentration in plant parts. The results suggest that C. rossii is able to hyperaccumulate Cd and can be a promising candidate for phytoextraction of Cd from polluted soils.

“…Zn 2+ in soil has been proved to be a competing ion for Cd 2+ [ 58 ]. Zn has been reported to inhibit Cd accumulation in all organs of tomato ( Lycopersicon esculentum ) [ 59 ], but to significantly enhance Cd accumulation in petioles and reduce accumulation in the roots of Potentilla griffithii [ 60 ]. The Zn content of blueberry was strongly affected by plant exposure to Cd.…”

Transcriptomics of different tissues of blueberry and diversity analysis of rhizosphere fungi under cadmium stress

Blueberry (Vaccinium ssp.) is a perennial shrub belonging to the family Ericaceae, which is highly tolerant of acid soils and heavy metal pollution. In the present study, blueberry was subjected to cadmium (Cd) stress in simulated pot culture. The transcriptomics and rhizosphere fungal diversity of blueberry were analyzed, and the iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) and cadmium (Cd) content of blueberry tissues, soil and DGT was determined. A correlation analysis was also performed. A total of 84 374 annotated genes were identified in the root, stem, leaf and fruit tissue of blueberry, of which 3370 were DEGs, and in stem tissue, of which 2521 were DEGs. The annotation data showed that these DEGs were mainly concentrated in a series of metabolic pathways related to signal transduction, defense and the plant–pathogen response. Blueberry transferred excess Cd from the root to the stem for storage, and the highest levels of Cd were found in stem tissue, consistent with the results of transcriptome analysis, while the lowest Cd concentration occurred in the fruit, Cd also inhibited the absorption of other metal elements by blueberry. A series of genes related to Cd regulation were screened by analyzing the correlation between heavy metal content and transcriptome results. The roots of blueberry rely on mycorrhiza to absorb nutrients from the soil. The presence of Cd has a significant effect on the microbial community composition of the blueberry rhizosphere. The fungal family Coniochaetaceae, which is extremely extremelytolerant, has gradually become the dominant population. The results of this study increase our understanding of the plant regulation mechanism for heavy metals, and suggest potential methods of soil remediation using blueberry.

“…(2000) with durum wheat. In contrast, synergism between Zn and Cd has been reported in rice (Chino 1981) and tomato (Mohammad and Moheman 2009), with an increase in translocation of Cd from the roots to the shoots by increased Zn concentration in the media. Considering that root uptake, distribution and accumulation of Zn and Cd in plant tissues differ depending on the crop genotype (Stolt et al.…”

“…Similar geochemical and environmental properties of Cd and Zn may lead to their interaction during plant uptake, transport from roots to aboveground parts, accumulation in edible parts and their functions in plant cells (Cakmak et al. 2000, Mohammad and Moheman 2009). Interaction between Cd and Zn in uptake, translocation and accumulation in plant parts has been studied in solution culture or in pot experiment (Nan et al.…”

This work was undertaken to investigate the effect of zinc (Zn) nutrition on root antioxidative responses to cadmium (Cd) toxicity of three wheat genotypes differing in Zn efficiency. A hydroponic experiment was carried out in which two bread wheat genotypes (Triticum aestivum L. cvs. ‘Rushan’ and ‘Cross’) and one durum wheat genotype (Triticum durum L. cv. Durum) were exposed to three Zn2+ (10−11.11, 10−9.11 and 10−8.81 μm) and two Cd2+ (10−11.21 and 10−10.2 μm) activity levels. ‘Durum’ showed the highest root sulfhydryl (‐SH) groups content and activity of catalase (CAT), ascorbate peroxidase (APX), and superoxide dismutase (SOD) and the lowest root membrane permeability among the studied wheat genotypes. In ‘Durum’, Zn nutrition increased root ‐SH groups concentration of seedlings in Cd‐free nutrient solution. In ‘Cross’, as Zn2+ activity increased from 10−11.11 to 10−9.11 μm, root ‐SH groups concentration was increased while decreased with increasing Zn2+ to 10−8.81 μm. Cadmium increased root membrane permeability at both 10−11.11 and 10−9.11 μm Zn2+ levels. Activity of CAT and APX increased in roots of ‘Durum’ plants exposed to Cd at Zn2+ = 10−9.11 μm and thereafter decreased with increasing Zn2+ activity. In contrast, CAT and APX activity in roots of ‘Cross’ and ‘Rushan’ genotypes exposed to Cd decreased by increasing Zn activity to 10−9.11 μm and then increased at Zn2+ = 10−8.81μm. The results showed an increase in activities of antioxidative enzymes in Cd‐treated plants, although this increase was dependent on the crop genotype and Zn levels in the media.
