Suppression of the temperature-sensitive phenotype of a mutant of reovirus type 3.

A revertant of a reovirus group A temperature-sensitive mutant was crossed with wild type. More than 50 percent of the progeny were temperature sensitive. In all of the temperature-sensitive progeny examined by recombination tests, the temperature-sensitive lesion was in group A. The results indicate that the revertant was phenotypically suppressed.
