Summary of the vRNA regions involved in intermolecular vRNA interactions. vRNAs have different colours and are drawn to scale. Regions defined by deletion analysis are presented by rectangles that have the same colour as the interacting vRNA. Note that when only one of several overlapping deletions affects the interaction between two vRNAs, the region required for the interaction is shorter than this deletion, as the overlapping sequences are not required. Deletions that have limited effects are indicated by question marks. Sequences identified by ODN mapping or/and site-directed mutagenesis are indicated by asterisks.
