Plants need many different metal elements for growth, development and reproduction, which
must be mobilized from the soil matrix and absorbed by the roots as metal ions. Once taken …

Some plants can hyperaccumulate metal ions that are toxic to virtually all other organisms at
low dosages. This trait could be used to clean up metal-contaminated soils. Moreover, the …

Heavy metals are often present naturally in soils, but many human activities (eg mining,
agriculture, sewage processing, the metal industry and automobiles) increase their …

Heavy metal toxicity is one of the major concerns for agriculture and health. Accumulation of
toxic heavy metals at high concentrations in edible parts of crop plants is the primary cause …

Many trace metals are essential micronutrients, but also potent toxins. Due to natural and
anthropogenic causes, vastly different trace metal concentrations occur in various habitats …

Nutrient uptake by plants is essential for their development and for the passage of minerals
into the food chain, but it also faces several limitations. Whereas soil physicochemical …

Metals (trace elements) are essential for plants but become toxic at high concentration.
Remarkably, about 700 species worldwide are able to accumulate large quantities of metals …

Worldwide, the effects of metal and metalloid toxicity are increasing, mainly due to
anthropogenic causes. Soil contamination ranks among the most important factors, since it …

The mechanisms plants use to transport metals from roots to shoots are not completely
understood. It has long been proposed that organic molecules participate in metal …

Trace metal elements are essential for plant growth but become toxic at high concentrations,
while some non-essential elements, such as Cd and As, show toxicity even in traces. Thus …
