Effect of chemical sensitization on repair of potentially lethal irradiation injury in Rhizopus stolonifer sporangiospores

Rhizopus stolonifer sporangiospores were sensitized to gamma radiation by soaking several hours in iodoacetamide solution. Plating immediately after irradiation or after a 48-hr “holding” period permitted an evaluation of the effect of sensitization on repair. Sensitized spores always exhibited a re...

Description
Summary:Rhizopus stolonifer sporangiospores were sensitized to gamma radiation by soaking several hours in iodoacetamide solution. Plating immediately after irradiation or after a 48-hr “holding” period permitted an evaluation of the effect of sensitization on repair. Sensitized spores always exhibited a recovery from potentially lethal irradiation injuries. However, the size of the repaired fraction was always moderately smaller if the spores had been sensitized to iodoacetamide prior to irradiation.
