The micronutrients iron (Fe), zinc (Zn), and copper (Cu) are essential for plants and the humans and animals that consume plants. Increasing the micronutrient density of staple crops, or biofortification, will greatly improve human nutrition on a global scale. This review discusses the processes and genes needed to translocate micronutrients through the plant to the developing seeds, and potent...

Zinc is an essential micronutrient which plays a macro role in the growth and productivity of the plants. Zinc (Zn) deficiency hinders metabolic and physiological activity in plants due to its inevitable role as an enzyme cofactor. Many Indian soil exhibit Zn deficiency with the content much below the critical level of 1.5ppm. The conditions that make unavailability of zinc to plants are high p...

Zinc is an essential micronutrient for several physiological and biochemical processes. To investigate its transport in rice, we characterized OsZIP8, a rice ZIP (Zrt, Irt-like Protein) gene that is strongly up-regulated in shoots and roots under Zn deficiency. OsZIP8 could complement the growth defect of Zn-uptake yeast mutant. The OsZIP8-GFP fusion proteins were localized to the plasma membra...

Many metals are very important for normal plant growth and development. One of these metals is zinc – typically the second most abundant transition metal in organisms and a substantial micronutrient that plays different roles in plant physiology. Zinc is an essential component of over 300 enzymes. It is responsible for gene regulation and stabilization of protein structure including Zn fingers,...

Zinc is a necessary micronutrient in plants whose deficiency can alter essential functions in plant metabolism. High concentrations of Zn can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen species. On the other hand, sodium nitroprusside (SNP), a donor of nitric oxide (NO) can protect cells from oxidative damage produce by reactive oxygen species. In th...

Zinc (Zn) is an essential micronutrient for plants, playing catalytic or structural roles in enzymes, transcription factors, ribosomes, and membranes. In humans, Zn deficiency is the second most common mineral nutritional disorder, affecting around 30% of the world's population. People living in poverty usually have diets based on milled cereals, which contain low Zn concentrations. Biofortific...
