Abstract

Heavy-ion beams effectively induce DNA double strand breaks by their dense ionization effect on the irradiated cells. The degree of locally deposited energy is represented by the linear energy transfer（LET; the energy transferred per unit length, keV μm-1). The value of the LET can be controlled by selecting ion-species or controlling the velocity of the ions. We found the most effective LET on mutation induction in Arabidopsis thaliana, and that the size of deletions induced by heavyion irradiation increases as increasing the value of LET. Based on these results, we proposed "on demand mutagenesis", in which the value of LET is selected for individual research purposes. Here, we presented the detail of the LET effect in heavyion irradiation together with the recently produced beneficial mutants of einkorn wheat, chlorella, and brown seaweed, which will be seeds of green innovation.
