Abstract
Plants absorb a range of heavy metals from soil. Some of them such as Cu, Zn, Mn, Fe, Ni and Co are essential micronutrients while some are nonessential (Cd, Hg, and Pb) for plants. The nonessential heavy metal ions as well as essential ones can have toxic effect when present in supra-optimal values. Thus for normal plant growth, mechanisms must exist that satisfy the requirements of cellular metabolism by regulating the uptake and distribution of these metal ions within different cells and organelles, thereby avoiding hazardous effect from the toxic metals. Membrane transport systems are likely to be involved in transition metal transport. These include CDF family, Nramps, ZIP family, ABC transporters, heavy metal ATPases (HMAs) and CAX family antiporters, Cyclic Nucleotide Gated Channels (CNGC) and copper transporter. This review aims to provide an overview of the range of potential transport systems presently thought to be involved in the acquisition, distribution and homeostasis of heavy metals in plants. It will focus on the general properties of different transporter families apart from the detailed molecular structure with an additional note on transport of some essential and nonessential metals in plants.
