| Research Abstract |
This study focused on the direction of mutation in order to improve the efficiency of plant mutation breeding. The expression level of Arabidopsis genes involved in anthocyanin biosynthesis was elevated by sucrose treatment. The frequency of pigment-less mutants induced by ion beam irradiation was higher in sucrose-treated seedlings than in non-treated seedlings. This suggests the possibility that the highly-expressed genes are relatively mutable.
