Abstract
Induced mutations have a long history in both applied and basic aspects of rice research. During the past fifty years, over 500 rice varieties have been developed worldwide, either directly from induced mutants or as a result of crossing such mutants with other breeding lines. More recently, the genomes of the two major subspecies of rice, japonica and indica, have been sequenced. Analysis of the genome sequences has revealed over 30,000 predicted genes. With the structural genomics of rice well in hand, attention is now focused on confirming the identification of these genes and determining their function. This has led to the recent emphasis on the generation of large induced rice mutant populations for gene discovery/confirmation and functional analyses using forward and reverse genetic screens. This mini-review aims to highlight the contributions of induced rice mutants in agriculture and the current state of induced mutant resources for functional genomics.
