To rice DNA mismatch repair genes retrotransposon insertion mutant and the control of materials through the detection and analysis of point mutations, a clear nitrogen ion beam characteristics of radiation-induced point mutation;

in paddy rice DNA mismatch repair gene mutations, the reverse block, insert and its contrast with son for adoption, materials testing and analysis of Point mutations in clear nitrogen ion beam, radiation-induced mutation in nature;

Wrong matches the repair gene take paddy rice DNA the reversal stand insertion sudden change is and the comparison as the material, changes suddenly the examination through the syzygy and the analysis, is clear about a nitrogen ion beam exposure suggestion sudden change the characteristic;

Reversing stand insertion of DNA mismatch repair genes in rice mutant and its control for the material, through the detection of point mutations and analysis, clear characteristics of nitrogen ion beam irradiation induced point mutations;

Reversing stand insertion of DNA mismatch repair genes in rice mutant and its control for the material, through the detection of point mutations and analysis, clear characteristics of nitrogen ion beam irradiation induced point mutations;
