Plants require the proper balance of zinc (Zn) for normal growth and optimum yield. Interest
in Zn has risen in the last decade because Zn deficiency stress is extensive in many areas …

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

A better understanding of the role of the Arabidopsis ZIP family of micronutrient transporters
is necessary in order to advance our understanding of plant Zn, Fe, Mn, and Cu …

Developing tissues such as meristems and reproductive organs require high zinc, but the
molecular mechanisms of how zinc taken up by the roots is preferentially delivered to these …

Hyperaccumulators are being intensely investigated. They are not only interesting in
scientific context due to their “strange” behavior in terms of dealing with high concentrations …

Abstract Background Nicotiana sylvestris and Nicotiana tomentosiformis are members of the
Solanaceae family that includes tomato, potato, eggplant and pepper. These two Nicotiana …

Abstract Background Zinc (Zn) and iron (Fe) are essential micronutrients for plant growth
and development, their deficiency or excess severely impaired physiological and …

Being sessile in nature, plants respond to heavy metal stress in the environment in different
ways. The responses include immobilization, exclusion, chelation, and …

Copper and iron are essential micronutrients for most living organisms because they
participate as cofactors in biological processes, including respiration, photosynthesis, and …

The phytotoxic effects of copper (Cu) and cadmium (Cd) on plant growth are well
documented. However, Cu and Cd toxicity targets and the cellular systems contributing to …
