Isolation of carbon ions-induced mutants in exhibiting different anthocyanin accumulation patterns

Kitamura, Satoshi; Ono, Yutaka; Narumi, Issey*

Ion beams have been used for isolation of novel mutants in a number of plant species in our laboratory. Re-mutagenesis by secondary irradiation of ion beams to already-established ion beam-induced mutants would be effective to modify plant characters step-by-step, because ion beams are likely to induce mutations at the limited regions of the genome. Here, we try to adapt the re-mutagenesis by secondary ion beam irradiation in model plant , for obtaining flavonoid mutants that have not been found so far by standard mutagenesis and screening methods.
