Clarification of the korean Sacbrood Virus based on Nucleotide sequence analysis and a study on the usefulness of RNA dependent RNA Polymerase of viral genome
Sacbood virus (SBV) is an infectious disease, resulting in failure to pupate and death and kSBV is a disease caused perish Apis cerana of 75% in South Korea. RNA dependent RNA Polymerase(RdRP) is one of polyprotein of viral genome and an enzyme that catalyzes the replication of RNA from an RNA templates and an essential protein encoded in the genomes of all RNA containing viruses with no DNA stages. In this study, recombinant construct with RdRP partial region of kSBV was used for sequence analysis to clarify about Korean SBV. As a result it could be determined that the virus develops by infection of Korean Apis cerana called kSBV. Also, we named Apis cerana-kSBV-region to the name of the unique region of gene that kSBV has. In comparison of the RdRP region of bee RNA virus on nucleotide sequence, its sequence from same species have less variability as well as each virus species has a certainty of RdRp region. It indicated that mutations of RdRP region of each virus species is able to be a useful indicator of honeybee virus detection.
