Summary

The frequency of ultraviolet-induced adenine reversions relative to inositol reversions in the strainK3/17 ad-3A 38701: inos 37401 is influenced by temperature. Fewer adenine revertants are obtained from a given ultraviolet dose adminstered at 30°C than from the same dose administered at 2°C. The inositol reversion frequency and the percentage survival are not greatly affected by these differences in temperature. Temperature differences are only effective if a) applied during irradiation b) higher temperatures above 15°C are used. Possible explanations for these results are considered.
