Abstract
Tulip mild mottle mosaic disease, caused by tulip mild mottle mosaic virus (TMMMV, species Ophiovirus tulipae), was first reported in Japan in 1979. TMMMV has a negative-sense ssRNA genome and is closely related to ophioviruses such as Mirafiori lettuce big vein virus (MLBVV, Ophiovirus mirafioriense). However, its complete nucleotide sequence has not yet been reported. Therefore, in this study, we determined the complete nucleotide sequences of all four TMMMV segments. The 5′-terminal tetranucleotide sequences were highly conserved, and the five bases at the 5′ end were identical in all segments. Nucleotide sequence comparisons of the four segments showed the highest sequence identity to those of MLBVV (70–76% for the genomic RNA sequences and 81–87% for the amino acid sequences of each ORF, except for ORF2). The amino acid sequences of the coat proteins of TMMMV and MLBVV were found to be 83.1% identical, which is below the 85% threshold for assignment to the same species, indicating that these viruses belong to different species in the same genus.
期刊介绍:
Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
