Abstract

Soaking seeds of Arabidopsis in 0.005% streptomycin (SM) produced no second generation chlorophyll mutants. But when seeds were soaked in 0.005% SM for 20 hours before irradiation with X-ray, the percentage of chlorophyll mutants was lower than in plants obtained from seeds that were soaked in distilled water before exposure to X-ray. This protective action of SM was antagonized by 0.01 M Mncl₂. It is suggested that this change in the radiosensitivity of Arabdopsis by SM is caused by chelation of Mn⁺⁺ with SM, thus causing a deficiency of the Mn⁺⁺ ion, which is essential for the integrity of the chromosomes.
