FIG. 6.

Genome segment profiles of parental and reassortant ARV virions. Viral double-stranded RNA was isolated from concentrated virus stocks of the parental and reassortant viruses, and individual genome segments were resolved on SDS–12.5% PAGE gels. Gels were stained with ethidium bromide and visualized under UV illumination. Images were captured and enhanced with Adobe Photoshop, and negative images were printed. The parental ARV-176 and ARV-138 genome segment profiles are shown by themselves in the left-hand panel and included as markers on the gels that contain the reassortant genomes. Only a selected number of reassortants used in this study are shown.
