The root iron transporter 1 governs cadmium uptake in Vicia sativa roots.

Cadmium is a non-essential element for plants and that inhibits plant growth and development. The Zhangye Mawan (ZM) variety of Vicia sativa is more sensitive to Cd toxicity than that Lanjian 3# (L3) variety, but the underlying mechanism is not fully understood. Here, we demonstrated that ZM showed higher Cd accumulation than L3 based on root Cd content and Cd fluorescence intensity in root protoplasts.

Effects of different rootstocks on cadmium accumulation characteristics of the post-grafting generations of .

A pot experiment was conducted to study the effects of different rootstocks on the cadmium (Cd) accumulation characteristics of the post-grafting generations of Cd-hyperaccumulator plants. Five treatments, ungrafted and seedlings grafted on the rootstocks of , , , and , were utilized. The four rootstock grafts decreased the shoot biomass of the post-grafting generation compared with ungrafted.

Cutting after grafting affects the growth and cadmium accumulation of Nasturtium officinale.

The growth and cadmium (Cd) accumulation of emergent plant Nasturtium officinale R. Br. cuttings taken from plants grafted onto rootstocks of four terrestrial Cruciferae species were studied in a pot experiment.

Effects of mutual grafting on the cadmium accumulation characteristics of two ecotypes of Solanum photeinocarpum.

The effects of mutual grafting on the cadmium (Cd) accumulation characteristics of two ecotypes (farmland and mining) of the potential Cd-hyperaccumulator Solanum photeinocarpum were studied through a pot experiment for one month. Four treatments were used in the experiment: ungrafted farmland ecotype (F-CK), ungrafted mining ecotype (M-CK), the farmland ecotype as the scion grafted onto rootstocks of the mining ecotype (F-Scion), and the mining ecotype as the scion grafted onto rootstocks of the farmland ecotype (M-Scion). Mutual grafting increased the rootstock biomass of both S.

iTRAQ-Based Comparative Proteomic Analysis of the Roots of TWO Winter Turnip Rapes ( L.) with Different Freezing-Tolerance.

The freezing tolerance of roots is crucial for winter turnip rape ( L.) survival in the winter in Northwest China. Cold acclimation (CA) can alleviate the root damage caused by freezing stress.

iTRAQ-Based Quantitative Proteome Revealed Metabolic Changes in Winter Turnip Rape ( L.) under Cold Stress.

Winter turnip rape ( L.) is a large-scale winter-only oil crop cultivated in Northwest China. However, its cold-resistant molecular mechanism remains inadequate.

Identification of cold stress responsive microRNAs in two winter turnip rape (Brassica rapa L.) by high throughput sequencing.

Background: Low temperature is a major abiotic stress affecting the production of rapeseed in China by impeding plant growth and development. A comprehensive knowledge of small-RNA expression pattern in Brassica rapa under cold stress could improve our knowledge of microRNA-mediated stress responses.

Results: A total of 353 cold-responsive miRNAs, 84 putative novel and 269 conserved miRNAs, were identified from the leaves and roots of two winter turnip rape varieties 'Longyou 7' (cold-tolerant) and 'Tianyou 4' (cold-sensitive), which were stressed under - 4 °C for 8 h.

Overexpression of a Functional PCS1 Homolog Increases Cadmium Tolerance and Phytochelatins Synthesis in Arabidopsis.

Phytochelatins (PCs) catalyzed by phytochelatin synthases (PCS) are important for the detoxification of metals in plants and other living organisms. In this study, we isolated a gene () from and investigated its role in regulating cadmium (Cd) tolerance. Expression of was induced in roots of under Cd stress.

Cd-induced oxidative stress and lignification in the roots of two Vicia sativa L. varieties with different Cd tolerances.

We examined the effects of Cd on growth, lipid peroxidation, reactive oxygen species (ROS) accumulation, antioxidant enzymatic activity, and lignin content in the roots of two varieties of Vicia sativa. Treatment with Cd decreased plant growth and increased ROS and lipid peroxidation levels to a greater extent in the Cd-sensitive variety ZM than in the Cd-tolerant variety L3. Most hydrogen peroxide (H2O2) and superoxide anion (O2(•-)) were accumulated in the cell walls and extracellular spaces in response to Cd treatments.

Exogenous application of salicylic acid alleviates cadmium toxicity and reduces hydrogen peroxide accumulation in root apoplasts of Phaseolus aureus and Vicia sativa.

We examined ameliorative effects of salicylic acid (SA) on two cadmium (Cd)-stressed legume crops with different Cd tolerances, viz. Phaseolus aureus (Cd sensitive) and Vicia sativa (Cd tolerant). Cd at 50 μM significantly increased the production of hydrogen peroxide (H(2)O(2)) and superoxide anion (O(2)(·-) ) in root apoplasts of P.

Excess copper induces production of hydrogen peroxide in the leaf of Elsholtzia haichowensis through apoplastic and symplastic CuZn-superoxide dismutase.

The effects of excess copper (Cu) on the production of reactive oxygen species (ROS) and antioxidant enzyme activities in leaves of the Cu-accumulator Elsholtzia haichowensis Sun were investigated. The addition of 100 microM of copper significantly increased the accumulation of hydrogen peroxide (H(2)O(2)) and the activities of superoxide dismutase (SOD) and other antioxidant enzymes. The increase in SOD activity was attributable to an increase in apoplastic and symplastic copper-zinc superoxide dismutase (CuZn-SOD) activity.

Cadmium-induced accumulation of hydrogen peroxide in the leaf apoplast of Phaseolus aureus and Vicia sativa and the roles of different antioxidant enzymes.

The effects of cadmium (Cd) on the accumulation of hydrogen peroxide (H(2)O(2)) and superoxide anion (O(2)(-)) in leaves of Phaseolus aureus and Vicia sativa were investigated. Cadmium at 100 microM significantly increased the production of O(2)(-) and H(2)O(2), as well as the activities of plasma membrane-bound nicotinamide adenine dinucleotide phosphate (NADPH) oxidases and the symplastic and apoplastic activities of superoxide dismutase and ascorbate peroxidase in the leaves of both species. Apoplastic guaiacol peroxidase activity was significantly induced in the leaves of both species, particularly in P.
