gold uptake and tolerance in arabidopsis

gold uptake and tolerance in arabidopsis

Gold uptake and tolerance in Arabidopsis White Rose. Gold is a precious metal with a variety of industrial uses. The gold mining process is often incomplete, and discarded mine tailings contain quantities of gold uneconomical for conventional extraction. Previous work has indicated the potential to use plants for gold phytoextraction from these ...

Heavy Metal Tolerance in Arabidopsis thaliana -

2011-1-1  An Arabidopsis homologue of the human Fe-exporting protein IREG (iron-regulated) function is assigned to Ni tolerance in Arabidopsis under Fe-deficiency conditions (Schaaf et al., 2006). Although the human protein is involved in the exporting process of excess Fe in the cells, Arabidopsis homologue localized to the tonoplast membrane.

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 and Zn concentrations.

Chapter 1 - Heavy Metal Tolerance in Arabidopsis

In Arabidopsis, IRT1 is expressed in roots, is induced by iron deficiency, and has altered regulation in plant lines bearing mutations that affect the iron uptake system.

WRKY6 Transcription Factor Restricts Arsenate Uptake

The Arabidopsis thaliana PHOSPHATE TRANSPORTER TRAFFIC FACILITATOR1 mutant, in which general Pi transporter trafficking to the plasma membrane is altered and As(V) uptake is impaired, shows remarkable As(V) tolerance (González et al., 2005).

A role for the AtMTP11 gene of Arabidopsis in

The Arabidopsis AtMTP family of genes encode proteins of the cation diffusion facilitator (CDF) family, with several members having roles in metal tolerances. Four of the 11 proteins in the family form a distinct cluster on a phylogenetic tree and are closely related to ShMTP8, a CDF identified in the tropical legume Stylosanthes hamata that is implicated in the transport of Mn 2+ into the ...

Distinct redox signalling and nickel tolerance in

2020-2-1  In order to provide supplementary information, we compared Ni uptake and tolerance in the model plant Arabidopsis thaliana and in the metallophyte Brassica juncea, and our aim was to examine nickel-induced changes in hormonal distribution, in ROS, RNS, and RSS levels and in protein tyrosine nitration in the above species. 2. Materials and ...

Ethylene Mediates Response and Tolerance to

Ethylene Biosynthesis and Action Blockers Reduce the K + Starvation-Induced ROS Production in Roots. Potassium starvation induces an increase in ROS in Arabidopsis roots, which has been implicated in regulating gene transcription in response to low concentrations of K + (Shin and Schachtman, 2004).To test whether there is a relationship between ethylene and low K +-induced ROS production, we ...

Natural Variation of Root Traits: From Development to ...

The root system has a crucial role for plant growth and productivity. Due to the challenges of heterogeneous soil environments, diverse environmental signals are integrated into root developmental decisions. While root growth and growth responses are genetically determined, there is substantial natural variation for these traits. Studying the genetic basis of the natural variation of root ...

2019-5-26  Chemicals taken up into plants may be accumulated so leading to toxic effects. Uptake and phytotoxicity of free cyanide was determined with the willow-tree transpiration test. Willow sets were grown in sand and irrigated with varying levels of cyanide (CN). Toxicity was determined by measuring transpiration. At CN concentrations below 10 mg/L, no toxic effects were observed. At 20 mg/L ...

Yellow nutsedge WRI4 -like gene improves drought

2020-10-31  Cuticular wax plays important role in protecting plants from drought stress. In Arabidopsis WRI4 improves drought tolerance by regulating the biosynthesis of fatty acids and cuticular wax. Cyperus esculentus (yellow nutsedge) is a tough weed found in tropical and temperate zones as well as in cooler regions. In the current study, we report the molecular cloning of a WRI4-like gene from Cyperus ...

The CEP5 Peptide Promotes Abiotic Stress Tolerance,

The proteome and phosphoproteome of CEP5 overexpressing Arabidopsis seedlings have been determined. This revealed that CEP5 impacts abiotic stress-related processes. Subsequent genetic, physiological, biochemical, and pharmacological results demonstrated that CEP5-mediated signaling is relevant for osmotic and drought stress tolerance in Arabidopsis.
