Mutants are essential genetic materials to elucidation of biological functions of genes involved.
Mutants are essential genetic materials to elucidation of biologicalfunctions of genes involved. Characterization and isolation of genes in mutants is one of theresearch tasks in functional genomic era. T-DNA insertional mutagenesis has provided an efficientway to identify genes in plant species, in which the mutated genes could be rapidly isolated oncethe mutant was confirmed by T-DNA insertion. About 40 percent of 620 cloned Arabidopsis genes withmutant phenotypes were determined by T-DNA tagging. In recent years, a large number of T-DNAinsertional rice mutant pools were established. Moreover, three genes were successfully isolatedfrom rice.
