[Analysis of the reassorted influenza virus clone genome: data for use of ordered selection of RNA segments]. / Analiz genoma reassortantnykh klonov virusa grippa: dannye v pol'zu uporiadochennogo podbora RNK-segmentov.

Chicken embryonated eggs were coinfected with influenza A/FPV/Rostock and A/FPV/Weybridge strains. 25 plaque isolates were obtained from the mixed yield and their genetic content was analysed by polyacrylamide gel electrophoresis of H3-uridine-labelled vRNA in a modified gel system. At least 18 clones out of 25 plaque isolates proved to be reassortants; however, only one among them contained the homologous RNA-segments belonging to both parents. The results are in agreement with the concept of an ordered recruitment of vRNA-segments into virions.
