A population of rice genotypes containing maize transposes were generated for a mutant collection. These primary genotypes and progeny are available for generation of extended mutant populations.
The DNA flanking the inserts was isolated in more that 6000 plants, yielding a Flanking Sequence Tag (FST) database of tagged sites in the rice genome. More than half of the inserts were in genes, providing a resource for about 1000 tagged genes, including regulatory genes of interest belonging to the homeobox, MADS, kinase and resistance genes.
The FST database allows interested users to select the insertion line of interest and characterize the mutant using this reverse genetics facility. A number of mutant phenotypes were identified and that will enable the identification of tagged genes.
