• The genome sequences of different viruses were compared with the genome of their host silkworm.
• Short regions of sequence identity to the genome of silkworm in viruses were identified.
• The interaction between viruses and silkworm and their evolutional relationship were discussed.
With the recent availability of the genomes of many viruses and the silkworm, Bombyx mori, as well as a variety of Basic Local Alignment Search Tool (BLAST) programs, a new opportunity to gain insight into the interaction of viruses with the silkworm is possible. This study aims to determine the possible existence of sequence identities between the genomes of viruses and the silkworm and attempts to explain this phenomenon. BLAST searches of the genomes of viruses against the silkworm genome were performed using the resources of the National Center for Biotechnology Information. All studied viruses contained variable numbers of short regions with sequence identity to the genome of the silkworm. The short regions of sequence identity in the genome of the silkworm may be derived from the genomes of viruses in the long history of silkworm-virus interaction. This study is the first to compare these genomes, and may contribute to research on the interaction between viruses and the silkworm.
