We are just beginning to understand the metabolism of heavy metals and to use their
metabolic functions in biotechnology, although heavy metals comprise the major part of the …

Over the past 200 years emissions of toxic heavy metals have risen tremendously and
significantly exceed those from natural sources for practically all metals. Uptake and …

This new edition provides current information on the nutritional requirements of world crops.
It presents research on the acquisition, accumulation, transport, and functions of chemical …

Transition metals such as copper are essential for many physiological processes yet can be
toxic at elevated levels. Other metals (eg lead) are nonessential and potentially highly toxic …

Copper is an essential metal for normal plant growth and development, although it is also
potentially toxic. Copper participates in numerous physiological processes and is an …

Members of the ZIP gene family, a novel metal transporter family first identified in plants, are
capable of transporting a variety of cations, including cadmium, iron, manganese and zinc …

Copper is an essential metal for plants. It plays key roles in photosynthetic and respiratory
electron transport chains, in ethylene sensing, cell wall metabolism, oxidative stress …

Metal cation homeostasis is essential for plant nutrition and resistance to toxic heavy metals.
Many plant metal transporters remain to be identified at the molecular level. In the present …

Transition metals such as Fe, Cu, Mn, and Zn are essential minerals for normal plant growth
and development, although they can be toxic when present in excess. Thus, for healthy plant …

Heavy metal ions such as Cu2+, Zn2+, Mn2+, Fe2+, Ni2+ and Co2+ are essential
micronutrients for plant metabolism but when present in excess, these, and non-essential …
