METAL TRANSPORTERS IN PLANTS: A MINI REVIEW
USMAN IJAZ
Abstract
Metals such as zinc and iron are essential nutrients for plant growth and survival. These elements are involved in various biochemical and physiological process such as tolerance against biotic/abiotic stress and photosynthesis. Advancements in molecular and genetic techniques have identified various gene families, which are involved in metal transportation in plants. These include ZIP, NRAMP, ABC and CDF family. Plants often grow in limited availability of metals by developing complex metal transporter system. As the world population increases, food security and availability are major issues for the population. The fact that majority of cultivated soil have growth limiting problems with nutrient deficiency and a significant component of the world population is facing nutrient deficiency. It makes plants nutrient research a major area in meeting global de-mand for food production with enhanced nutrition. By improving the metal uptake efficiency and redistribu-tion in plant body, nutrients deficiency can be overcome globally. Current review is focused on metal transport proteins identified in different plants and how these metals contribute to plant growth and development.
