Up to two-thirds of the world population is at risk of deficiency in one or more essential mineral elements. In order to overcome deficiency disorders of mineral nutrients, biofortification approach in crops is an absolute requirement to eliminate the hidden hunger. Hence, the aim of crop biofortification is shifting from food security to nutritional security. In this context, ionomics becomes essential to identify potential gene(s) responsible for the uptake, transport, and storage of ions in plants. It involves the measurement of elemental composition of an organism and change in their composition in relation to physiological, developmental, environmental, and genetic factors. It renders the functional analysis of genes and gene networks that directly or indirectly affect the whole ionome. The present review deals with the study of ionome with special reference to different types of ionic interactions, quantifications, and gene identification.
