Due to their immutable nature, metals are a group of pollutants of much concern. As a result
of human activities such as mining and smelting of metalliferous ores, electroplating, gas …

Living systems are supported and sustained by the genome through the action of the
transcriptome, proteome, metabolome, and ionome, the four basic biochemical pillars of …

Regulation of iron uptake is critical for plant survival. Although the activities responsible for
reduction and transport of iron at the plant root surface have been described, the genes …

Worldwide more than 400 plant species are now known that hyperaccumulate various trace
metals (Cd, Co, Cu, Mn, Ni, and Zn), metalloids (As) and nonmetals (Se) in their shoots. Of …

The frd3 mutant of Arabidopsis exhibits constitutive expression of its iron uptake responses
and is chlorotic. These phenotypes are consistent with defects either in iron deficiency …

Many natural and agricultural ecosystems are characterized by sub-optimal availability of
mineral nutrients and ion toxicities. Mineral stresses are likely to have important, complex …

Plants have evolved complex strategies to maintain phosphate (Pi) homeostasis and to
maximize Pi acquisition when the macronutrient is limiting. Adjustment of root system …

Background It has become increasingly evident that dietary Se plays a significant role in
reducing the incidence of lung, colorectal and prostate cancer in humans. Different forms of …

The sporophyte of the fern Pteris vittata is known to hyperaccumulate arsenic (As) in its
fronds to> 1% of its dry weight. Hyperaccumulation of As by plants has been identified as a …

Here we describe the development of a microarray-based mapping strategy to rapidly
isolate deletion mutant genes. The presented approach is particularly useful for mapping …
