Chimeric RNAs generated in the silkworm midgut infected with BmCPV.

A, Circos diagram of chimeric RNAs in the midgut at 48 h (BmCPV_48), 96 h (BmCPV_96) and 144 h (BmCPV_144) post-infection with BmCPV; B, Fusion types of chimeric RNAs detected in the midgut infected with BmCPV. “BMSK_X” indicates the individual silkworm chromosomes. Each line in the Circos plots represents a fusion event; the red line represents the fusion event between two RNA molecules originating from the same chromosome, while the blue line represents the fusion event between RNA molecules originating from different chromosomes/BmCPV genomic dsRNA segment. The circle at one end of the wavy line represents the 5’-end of RNA molecule.
