Abstract
The complete genome sequence of Orthotospovirus tomatozonae (tomato zonate spot virus, TZSV) isolated in Japan was determined and compared with that of Chinese isolates. The lengths of the S, M, and L segments of the RNA genomes of the Japanese isolate (TZSV-TZ1-3) were 3194, 4675, and 8916 nucleotides, respectively, which were similar to the Chinese isolates. Moreover, the eight motifs on the RNA-dependent RNA polymerase (RdRp) gene were conserved in both TZSV-TZ1-3 and Chinese TZSV isolates (TZSV-Bidens and TZSV-Tomato-YN). The nucleotide identity of the genes among the TZSV isolates was more than 94%, indicating low diversity among viruses. The phylogenetic analysis and the prediction of the cleavage sites in the glycoprotein showed that the TZSV-TZ1-3 isolate was closely related to TZSV-Tomato-YN isolated from China. However, there were unique frameshifts and deletions on the RdRp and glycoprotein genes of the TZSV-Tomato-YN isolate, suggesting that both isolates were genetically distinct. The findings of this study indicate that the TZSV-TZ1-3 isolate originated in China and show the sequence diversity among TZSV isolates.
期刊介绍:
Viruses are convenient models for the elucidation of life processes. The study of viruses is again on the cutting edge of biological sciences: systems biology, genomics, proteomics, metagenomics, using the newest most powerful tools.
Huge amounts of new details on virus interactions with the cell, other pathogens and the hosts – animal (including human), insect, fungal, plant, bacterial, and archaeal - and their role in infection and disease are forthcoming in perplexing details requiring analysis and comments.
Virus Genes is dedicated to the publication of studies on the structure and function of viruses and their genes, the molecular and systems interactions with the host and all applications derived thereof, providing a forum for the analysis of data and discussion of its implications, and the development of new hypotheses.
