Eleven temperature-sensitive (ts) mutants of influenza A (fowl plague, Rostock) virus were analysed for in vitro RNA transcriptase activity in reactions primed by ApG or globin rnRNA at 31 °C or at 40.5 °C, the restrictive temperature for ts mutant growth. Only those ts mutants studied which were defective in RNA segment 1, coding for the virion P2 protein, were defective in RNA transcriptase activity when compared to wild-type virus. Mutants having a defect in the P2 protein had no significantdoi:10.1099/0022-1317-57-2-407 pmid:6895649 fatcat:7gnt3b5uynhyhc3svvjswm4s5u
