Abstract Spatial imaging of cadmium (Cd) in the hyperaccumulator Sedum alfredii was investigated vivo by laser ablation inductively coupled plasma mass spectrometry and x-ray microfluorescence imaging. Preferential Cd accumulation pith cortex observed stems hyperaccumulating ecotype (HE), whereas restricted to vascular bundles its contrasting nonhyperaccumulating ecotype. concentrations up 15,000 μg g−1 were measured cells, which many fold higher than stem epidermis HE plants. In leaves HE,...
Two genes encoding CAX2-like proteins were isolated from a Zn/Cd hyperaccumulating ecotype (HE) and nonhyperaccumulating (NHE) of Sedum alfredii Hance, they named SaCAX2h SaCAX2n, respectively. Both SaCAX2h:eGFP SaCAX2n:eGFP localized to the vacuolar membrane tobacco epidermal cells yeast mutants. Heterologous expression or SaCAX2n in Δzrc1 mutant increased Cd content cells. Yeast complementary assay also revealed that both transporters could suppress Ca Mn hypersensitivity enhance...
Abstract Understanding cadmium (Cd) accumulation in plants is critical for the development of plant-based strategies soil remediation and crop safety. Sedum alfredii a nonbrassica plant species known to hyperaccumulate Cd. The characteristics Cd uptake, distribution, retranslocation affected by Ca status were investigated at cellular levels S. alfredii. Low supply significantly increased contents shoots alfredii, particularly young leaves. Micro x-ray fluorescence images confirmed that...
Hyperaccumulators are the preferred materials for phytoremediation. Sedum alfredii Hance is a cadmium (Cd) hyperaccumulator plant in China, although its detoxification mechanism remains unresolved. In our study, we cloned gene belonging to resistance (PCR) family, named SaPCR2, from hyperaccumulating ecotype (HE) of S. alfredii. Sequence analysis indicated that SaPCR2 contained cysteine-rich domain highly conserved PCR family and played an important role Cd detoxification. Based on relative...
Sedum alfredii Hance is a perennial herb native to China that can particularly be found in regions with abandoned Pb/Zn mines. It Cd/Zn hyperaccumulator highly tolerant Pb, Cu, Ni, and Mn, showing potential for phytoremediation of soils contaminated multiple heavy metals. A better understanding how this species responds different metals would advance the efficiency. In study, transcriptomic regulation S. roots after Cd, Zn, Cu exposure was analyzed explore candidate genes involved...
Rhizo-microbe recruited by hyperaccumulating plants are crucial for the extraction of metals from contaminated soils. It is important, but difficult, to identify specific rhizosphere microbes hyperaccumulators shaped root exudation. Continuous 13CO2 labeling, microbial DNA-based stable isotope probing (DNA-SIP), and high throughput sequencing were applied those microorganisms using exudates Cd hyperaccumulator Sedum alfredii. In contrast its non-hyperaccumulating ecotype (NAE), (HAE) S....
The systemic inflammatory response index (SIRI), a novel inflammation maker, has proven to be associated with prognostic outcomes in various diseases. However, few studies have been conducted assessing how SIRI may influence of patients on peritoneal dialysis (PD). Herein, we assessed the predictive value mortality all-cause mortality, including cardiovascular disease (CVD) PD patients.
Aluminum (Al) toxicity in acid soils is a primary factor limiting plant growth and crop yield worldwide. Considerable genotypic variation resistance to Al has been observed many species. In wheat (Triticum aestivum L.), phytotoxicity complex phenomenon involving multiple physiological mechanisms which are yet be fully characterized. To elucidate the molecular basis of wheat, we performed detailed analysis reactive oxygen species (ROS) nitrogen (RNS) under stress one Al-tolerant (Jian-864)...
Chinese bayberry ( Myrica rubra ) is a popular, nutrient- and antioxidant-rich fruit in Asia. However, it susceptible to Drosophila during ripening, which disrupts production causes economic loss. This study compared the effects of insecticides, insect-proof nets (IPNs), insect- rain-proof (IRPNs) on quality. was absent fruits from IPN- or IRPN-treated trees but only significantly reduced by insecticides. IPNs IRPNs increased diameter, weight, edible rate Brix/acid ratio, had strongest...
Understanding the influence of heavy metal cadmium (Cd) on phyllosphere microbiome hyperaccumulator plants is crucial for enhancing phytoremediation. The characteristics Sedum alfredii Hance, a plant, were investigated using 16S rRNA and internal transcribed spacer amplicon sequencing powdery mildew-infected leaves treated or untreated with Cd. results showed that colonization mildew caused severe chlorosis necrosis in S. leaves, relative abundance Leotiomycetes infected increased...
Sedum alfredii Hance (S. alfredii) is a native hyperaccumulator plant species in China that has strong tolerance and accumulation ability for Zn Cd. In addition, it good material the phytoextraction of soil heavy metal pollutants. However, specific effect high concentrations on growth S. its metabolic mechanisms are not clear. Using an untargeted metabolomics method, we analysed differential metabolites two ecotypes roots under different treatments. The results showed levels significantly...
Short-term responses of Sedum alfredii roots to Cd exposure was compared in hyperaccumulator (HE) and nonhyperaccumulating ecotype (NHE). Cadmium significantly inhibited root elongation induced loss plasma membrane integrity lipid peroxidation tips the NHE, whereas these effects were much less pronounced HE plants. A strong accumulation reactive oxygen species with increasing concentration noted NHE tips, but not HE. After exposure, a dose-dependent decrease oxidized glutathione marked...
