Fig. 4: Identification of defective interfering particle (DIP)-associated junctions in different influenza virus populations.

A Number of distinct junctions detected in each individual in three passage lineages at the indicated time points. B Number of distinct junctions detected in each viral segment in the naïve and vaccinated lineages. C Plots showing the viral DIP-associated junctions present in the overall viral populations from the naïve group. Each color indicates a particular DIP-associated junction, whose relative proportion corresponds to its abundance in the viral population in the indicated sample.
