Investigating the Toxicity, Uptake, Nanoparticle

Gold Uptake at the Genetic Level. Several studies have investigated the binding of various states of gold to root membranes , , but at the genetic level, the mechanism for gold uptake remains unclear.In Arabidopsis, heavy metal ATPases (HMAs), which translocate ions across cell or organelle membranes, have been implicated in thecadmium uptake translocation and tolerance in the,Cadmium uptake, translocation and tolerance in the hyperaccumulator Arabidopsis halleri , mechanisms of tolerance to copper and cadmium are compromised by a . Unravelling cadmium toxicity and tolerance in plants , This property implies several physiological strategies linked to both reduced metal uptake and tolerance , of cadmium binding,NIP1;2 is a plasma membrane-localized transporter,,uptake requires a functional ALMT1-mediated root malate ex-udation system. Therefore, coordination between the Al exclu-sion and the internal Al tolerance mechanisms is required to achieve overall Al tolerance in Arabidopsis.

Cold-Induced Freezing Tolerance in Arabidopsis | Plant,

Abstract. Changes in the physiology of plant leaves are correlated with enhanced freezing tolerance and include accumulation of compatible solutes, changes in membrane composition and behavior, and altered gene expression.Heavy Metal Tolerance in Arabidopsis thaliana,Overexpression of Arabidopsis PCS1 gene confers Cd tolerance in plants, for example, tobacco (Pomponi et al., 2006), and animals (Konishi et al., 2006), indicating the crucial role of PCSs in Cd tolerance.Cadmium Uptake, Translocation, and Tolerance in,Information on cadmium (Cd) uptake and transport is essential to understand better the physiology of Cd tolerance in plants. In this study, Cd uptake, translocation, and tolerance were investigated in AHA1 (Arabidopsis plasma membrane H +-ATPase gene) overexpressed plants.

An Assay to Test Manganese Tolerance in Arabidopsis

Manganese (Mn) is an essential nutrient required for the catalytic or regulatory function of several cellular enzymes. However, excessive Mn concentrations in plant tissues are toxic to plant cells as they negatively affect enzymatic activities, lead to oxidative stress and disturb the uptake and distribution of other essential mineral elements (Ca, P, Mg or Fe).Polyploids Exhibit Higher Potassium Uptake and,Chao et al. (p. 658, published online 25 July) identified accessions of the model plant Arabidopsis thaliana with naturally doubled genomes and found that the cytotype of the root, but not shoot, in these natural, as well as in artificially induced, polyploid plants appears to confer increased salt tolerance by regulating leaf potassium levels.Cadmium Uptake, Translocation, and Tolerance,Cadmium Uptake, Translocation, and Tolerance 229 sterilization, Arabidopsis seeds of 80 to 100 were planted in 1/6 MS solution with volume of 140 ml for 7 days, and then submitted to different,

Functional Redundancies in Cyanide Tolerance Provided

With regard to possible redundancies between the β-CAS and sulfurtransferase pathways, the results offer some support for the contention that the β-CAS pathway is the principal mechanism for cyanide detoxification in Arabidopsis and that the sulfurtransferase pathway does not provide cyanide tolerance in vivo.Cadmium uptake, translocation and tolerance in the,,Arabidopsis halleri is a well‐known zinc (Zn) hyperaccumulator, but its status as a cadmium (Cd) hyperaccumulator is less certain. Here, we investigated whether A. halleri can hyperaccumulate Cd and whether Cd is transported via the Zn pathway.. Growth and Cd and Zn uptake were determined in hydroponic experiments with different Cd andInvestigating the Toxicity, Uptake, Nanoparticle,That gold is able to trigger these control mechanisms, down-regulating divalent cation transporters to reduce gold uptake and subsequent toxicity, implies that some proportion of gold in the environment exists in a cation form, and that these transporters have activity towards gold.

Nanoparticle Uptake in Plants: Gold Nanomaterial

Terrestrial plants can internalize and translocate nanoparticles (NPs). However, direct evidence for the processes driving the NP uptake and distribution in plants is scarce at the cellular level. Here, NP-root interactions were investigated after 10 days of exposure of Arabidopsis thaliana to 10 mg·L–1 of negatively or positively charged gold NPsExpression of Arabidopsis CAX2 in Tobacco. Altered,Metal transport from the cytosol to the vacuole is thought to be an important component of ion tolerance and of a plant's potential for use in phytoremediation. The Arabidopsis antiporter CAX2 (calcium exchanger 2) may be a key mediator of this process. CAX2 expression in yeast suppressed both Ca2+ and Mn2+ growth defects.
