title: [Role of the NS gene in regulating the synthesis of RNA-segments of the influenza A virus].
abstract: To find the role of any influenza virus gene in regulation of the RNA-segments replication the transfer of ts-mutants to nonpermissive temperature on the late step of infection has been used (shift-up). The mutants having impaired the NS or NP-genes have been obtained and studied. The transfer of mutants to partially nonpermissive conditions (when the amount of replication is decreased, but it still continues) results in the distinct return to the early mode of replication in ts-mutant with the mutation in NS-gene. This suggests the NS-gene role in replication of viral RNA-segments, in particular, in the switch from the "early" stage of replication to the "late" one. In NP-gene mutant only the decrease in general replication takes place without the shift to "early" replication mode.
