British Library EThOS: Gold uptake and tolerance in

The aims of this study were therefore to characterise gold uptake and nanoparticle formation in the model plant species Arabidopsis thaliana and subsequently investigate the transcriptional response to gold to identify mechanisms of uptake and tolerance. A number of approaches were used to investigate the gold tolerance and uptake by Arabidopsis.

Cadmium uptake, translocation, and tolerance in AHA1OX

In this study, Cd uptake, translocation, and tolerance were investigated in AHA1 (Arabidopsis plasma membrane H(+)-ATPase gene) overexpressed plants. Exposed to 10 µM CdCl(2), AHA1OX showed a higher root elongation, accumulated more Cd, and maintained better integrity of nucleus membrane of root tips in comparison to the control plant (WT

Arabidopsis Transporter MGT6 Mediates Magnesium

Although magnesium (Mg 2+) is the most abundant divalent cation in plant cells, little is known about the mechanism of Mg 2+ uptake by plant roots. Here, we report a key function of Magnesium Transport6 (MGT6)/Mitochondrial RNA Splicing2-4 in Mg 2+ uptake and low-Mg 2+ tolerance in Arabidopsis thaliana. MGT6 is expressed mainly in plant aerial tissues when Mg 2+ levels are high in the soil or

Heavy Metal Tolerance in Arabidopsis thaliana ScienceDirect

2011-1-1  Metal exclusion-mediating HM tolerance is regulated by HMA4 and HMA5. HMA4 and HMA5 have been identified as critical genes for Cd tolerance in typical Cd-hyperaccumulating species, Arabidopsis halleri ( Hanikenne et al ., 2008 ), and in some Cu hypersensitive accessions of A. thaliana ( Kobayashi et al ., 2008 ).

Polyploids Exhibit Higher Potassium Uptake and Salinity

Genome duplication (or polyploidization) has occurred throughout plant evolutionary history and is thought to have driven the adaptive radiation of plants.

Thioarsenate Toxicity and Tolerance in the Model System

2021-3-12  Thioarsenates form from arsenite under sulfate-reducing conditions, e.g., in rice paddy soils, and are structural analogues of arsenate. Even though rice is one of the most important sources of human arsenic intake, nothing is published about uptake, toxicity, or tolerance of thioarsenates in plants. Experiments using the model system Arabidopsis thaliana showed that monothioarsenate is less

Variation in copper tolerance in Arabidopsis thaliana

2007-1-10  Among the Arabidopsis thaliana accessions Columbia (Col), Landsberg erecta (Ler), and Wassilewskija (Ws), Ler and Ws showed higher copper (Cu) tolerance than Col, while accumulating more Cu. Thus, Cu tolerance did not appear to be related to metal exclusion. Rather, the higher Cu tolerance of Ler and Ws may reflect less Cu‐induced nutrient deficiency as they maintained higher sulfur, iron
