ABSTRACT: In the present era of
genomics, ionomics is one of the major pillars for the structural and
functional genomic study. The complete set of ions present in an organism is
referred to as the ionome of the organism. Hence, the ionomics is defined as
the, “study of quantitative complement of low molecular weight molecules
present in cells in a particular physiological and developmental state of the
plant” [1]. The complete
ionomic profiling of the plants are done by using a number of analytical tools
like ICP-MS, ICP-OES, X-Ray crystallography, Neutron Activation Analysis (NAA)
etc. All these analytical tools gave complete profile of the ions present in
the plants. These data are stored in a database called PiiMS (Purdue Ionomics Information
Management System) [2]. The huge data available in the database helps in the
forward and reverse genetic approach for studying the structural and functional
genomics of the particular organism. This review describes the role of the
ionomic study in crop plants like arabidopsis, rice and maize.
