Abstract

In the developing countries, approximately 3.1 billion people reside in remote areas, and 2.5 billion of these people rely on farming for subsistence, which provides 30% to productivity expansion due to the GDP produced from agriculture. Plants’ physiochemical functions, for instance, pigment (chlorophyll) production, photosynthesis, nucleic acid synthesis, peptide modifications, oxidation-reduction reaction, carbohydrate metabolism, and nitrification, depend greatly on micro- and macronutrients. Metal and metalloid toxic effects are becoming more prevalent around the world, owing mostly to human sources. Soil pollution is one of the most significant variables because it impacts agricultural output allowing the metals and metalloid ions to permeate the food chain and experience bioaccumulation, resulting in repercussions on health and environmental changes. Throughout evolution, plants have evolved various ways to deal with biotic and abiotic stressors. Plants employ various metal and metalloid transporters to maintain intraorganellar homeostasis in order to provide resilience toward their toxicity. These includes NRAMP, CDF, ZIP, ABC, HMAs, NIP, BOR, and Lsi2 transporters. This chapter provides a potential understanding of several putative transporters that are currently believed to be involved in the accumulation and transport of metals and metalloids in plants. Apart from the specific structure, this chapter focuses on the properties of several transporter families, with a specific attention on transportation of metals.
