The CpGV-WW fingerprint regions a and b are located in p45, dnapol, desmoplakin, lef3, iap5, lef9, dna-ligase, which are supposed to be involved in viral DNA replication and BV production (Supplementary Table S2), in which the SNPs result in amino acid sequence changes and may cause virulence differences between the two viruses observed in infection experiments of larvae with type I (CpRR1) and type II (CpR5M) resistances are of interest (Fan et al. The gene discussed is DSP; the disease is infection.
