The bHLH Transcription Factor POPEYE Regulates Response to Iron Deficiency in Arabidopsis Roots[W][OA]
Iron deficiency induces a range of physiological responses that are controlled by transcriptional alterations concentrated in the root pericycle. The transcriptional regulator POPEYE regulates manyExpand

Genomic scale profiling of nutrient and trace elements in Arabidopsis thaliana
Understanding the functional connections between genes, proteins, metabolites and mineral ions is one of biology's greatest challenges in the postgenomic era. We describe here the use of mineralExpand

Natural Variants of AtHKT1 Enhance Na+ Accumulation in Two Wild Populations of Arabidopsis
Plants are sessile and therefore have developed mechanisms to adapt to their environment, including the soil mineral nutrient composition. Ionomics is a developing functional genomic strategyExpand

Mutations in Arabidopsis Yellow Stripe-Like1 and Yellow Stripe-Like3 Reveal Their Roles in Metal Ion Homeostasis and Loading of Metal Ions in Seeds1
Here, we describe two members of the Arabidopsis (Arabidopsis thaliana) Yellow Stripe-Like (YSL) family, AtYSL1 and AtYSL3. The YSL1 and YSL3 proteins are members of the oligopeptide transporterExpand

A Coastal Cline in Sodium Accumulation in Arabidopsis thaliana Is Driven by Natural Variation of the Sodium Transporter AtHKT1;1
The genetic model plant Arabidopsis thaliana, like many plant species, experiences a range of edaphic conditions across its natural habitat. Such heterogeneity may drive local adaptation, though theExpand

The Effect of Iron on the Primary Root Elongation of Arabidopsis during Phosphate Deficiency1[W][OA]
Root architecture differences have been linked to the survival of plants on phosphate (P)-deficient soils, as well as to the improved yields of P-efficient crop cultivars. To understand how theseExpand

Identifying model metal hyperaccumulating plants: germplasm analysis of 20 Brassicaceae accessions from a wide geographical area
Summary • Here we report on the first phase of a funded programme to select a wild relative of Arabidopsis thaliana for use in large-scale genomic strategies, including forward and reverse geneticExpand

The Ferroportin Metal Efflux Proteins Function in Iron and Cobalt Homeostasis in Arabidopsis[W][OA]
Relatively little is known about how metals such as iron are effluxed from cells, a necessary step for transport from the root to the shoot. Ferroportin (FPN) is the sole iron efflux transporterExpand

Arabidopsis pdr2 reveals a phosphate-sensitive checkpoint in root development.
Plants have evolved complex strategies to maintain phosphate (Pi) homeostasis and to maximize Pi acquisition when the macronutrient is limiting. Adjustment of root system architecture via changes inExpand

Functional Association of Arabidopsis CAX1 and CAX3 Is Required for Normal Growth and Ion Homeostasis1
Cation levels within the cytosol are coordinated by a network of transporters. Here, we examine the functional roles of calcium exchanger 1 (CAX1), a vacuolar H+/Ca2+ transporter, and the closelyExpand
