Taking advantage of these massive troves of genomic information that is increasingly available for a number of plant species, induced mutants are used in identifying and ascribing functions to genes. The genomic region(s) implicated in the expression of a trait, i.e., the gene, is identified by studying a series of induced mutants vis-à-vis the normal or wildtype variants. Adopting the deductive process of identifying which traits have been modified and relating the modifications to changes in genomic regions of the induced mutants, as compared to the normal types, the gene(s) controlling a trait may be identified.
