Research Areas

Ion beam breeding team studies various biological effects of fast heavy ions. It also develops new technique to breed plants and microbes by heavy-ion irradiations. Heavy ions can produce dense and localized ionizations in matters along their tracks. These localized and dense ionization can cause DNA double-strand breaks which are not easily repaired and result in mutation more effectively than single-strand breaks. Its research subjects cover physiological study of DNA repair, genome analyses of mutation, and development of mutation breeding of plants by heavy-ion irradiation. Some new cultivars have already been brought to the market.
