Abstract

The HRS/IRR in Escherichia coli had been investigated withE.coli K12 wild strain MG1655 irradiated by the 30 keV N⁺. The curve of the dosesurvival effect showed the 30 keV N⁺ ion could induce the HRS/IRR at the dose less than 10×10¹⁴ ions/cm². Moreover， the effect of recA gene in HRS/IRR inducement had been researched with three E.coli K12 strains， wild strain MG1655， LE392 (recA+) and DH5α(recA-). The results showed the IRR was disappeared in recA- DH5α strain， but the HRS/IRR appeared in wild strain MG1655 and recA⁺ LE392， which suggested that recA  gene and the DNA damages & their repairs including recA gene were essential element in HRS/IRR inducement.
