Abstract

Twenty-six temperature-sensitive (ts) mutants of United Kingdom tissue culture-adapted bovine rotavirus were isolated and characterized. Fourteen of these mutants were determined to be ts both by efficiency of plating and by virus yield at the nonpermissive temperature of 39.5 degrees C as compared with that at the permissive temperature of 32 degrees C. The remaining mutants were only ts by the criterion of efficiency of plating. High-frequency recombination (gene reassortment) was observed when some pairs of mutants were crossed, and this allowed the classification of the mutants into five separate recombination groups. Groups III and V have prototype ts mutants (ts34 and ts115, respectively) that do not synthesize RNA or polypeptides at 39.5 degrees C. The other groups, I, II, and IV, have prototype mutants (ts17, ts7, and ts6, respectively) that synthesize both RNA and polypeptides at 39.5 degrees C, although ts17 does so only at a reduced level.
