Apr 17, 2012· Natural Variation in PQ Tolerance in Arabidopsis Accessions.. To identify the loci responsible for the natural variation in PA/PQ transport, Arabidopsis accessions showing alterations in PA/PQ tolerance were screened for primary root growth in PA- or PQ-containing media. Whereas none of the accessions examined displayed PA tolerance, several accessions, such as Nos-d, Est-1, Lov …

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 ...

Ethylene response factors (ERFs) are involved in the regulation of plant responses to biotic and abiotic stresses. Here we provide evidence for a role of ERF96, a member of the ERF transcription factor group IX, in selenite tolerance in Arabidopsis.ERF96 gene was rapidly up-regulated in response to selenite stress. Overexpression of ERF96 enhanced Arabidopsis resistance to selenite stress ...

Genome duplication (or polyploidization) has occurred throughout plant evolutionary history and is thought to have driven the adaptive radiation of plants. We found that the cytotype of the root, and not the genotype, determined the majority of heritable natural variation in leaf potassium (K) concentration in Arabidopsis thaliana. Autopolyploidy also provided resistance to salinity and may ...

Rice cytosolic O-acetylserine(thiol) lyase OASTL-A1 plays an important role in non-protein thiol biosynthesis in roots essential for As detoxification.
Arabidopsis plants lacking functional RbohD also showed the highest Cd 2+ uptake by roots (Supplemental Fig. S5, D and E). Similar to the results observed for pak choi seedlings, HRW pretreatment reduced Cd uptake by Arabidopsis wild-type (Col-0) roots; this ameliorative effect was absent in AtrbohD and AtrbohF mutants, regardless of the root ...
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 NPs (∼12 nm) in gels.
Overall, these results indicate that disruption of the PRT6 gene confers increased tolerance to high salt in Arabidopsis, whereas it conversely reduced salinity tolerance in maize. In wheat, we compared two genotypes with distinct nitrogen use efficiency (NUE), VA08MAS-369 and VA07W-415, to determine critical traits involved in NUE regulation.
We have studied the physiological and genetic responses of Arabidopsis thaliana L. (Arabidopsis) to gold. The root lengths of Arabidopsis seedlings grown on nutrient agar plates containing 100 mg/L gold were reduced by 75%. Oxidized gold was subsequently found in roots and shoots of these plants, but gold nanoparticles (reduced gold) were only observed in the root tissues.

ABSTRACT: The Arabidopsis aquaglyceroporin NIP7;1 is involved in uptake and tolerance to the trivalent arsenic species arsenite.
Lesion of LKS1 significantly reduced K+ uptake and caused leaf chlorosis and growth inhibition, whereas overexpression of LKS1 significantly enhanced K+ uptake and tolerance to low K+. We demonstrate that CIPK23 directly phosphorylates the K+ transporter AKT1 and further find that CIPK23 is activated by the binding of two calcineurin B-like ...

When overexpressed in yeast and Arabidopsis, PtoABCG36 could decrease Cd accumulation and confer higher Cd tolerance in transgenic lines than in wild-type (WT) lines. Net Cd 2+ efflux measurements showed a decreasing Cd uptake in transgenic Arabidopsis roots than WT. These results demonstrated that PtoABCG36 functions as a cadmium extrusion ...

Gold Uptake from Liquid Medium by Arabidopsis. To investigate gold uptake by Arabidopsis, plants were grown in liquid culture. After 3 weeks of growth, the plants had produced predominantly shoot and leaf tissues, with approximately 5% dry weight comprising root tissues.
Aluminum (Al) toxicity is a major constraint for crops grown on acid soils. Various plant species have adopted an Al exclusion/avoidance mechanism and/or internal tolerance mechanisms to ameliorate Al toxicity. In Arabidopsis , the root organic acid exudation-based Al exclusion mechanism has been well characterized; however, no evidence for an internal Al tolerance mechanism has been reported.

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 ...
Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with ...
