To identify the virus pathogen inducing tomato(Solanum lycopersicum L.)mosaic and curl
disease at Jinzhong City of Shanxi Province,the technology of double-stranded RNA(dsRNA)and sequenceindependent
amplification(SIA)were used.Results of SIA and sequencing showed that there was Tobacco
mosaic virus(TMV)in affected tomato leaves.Further cloning the whole genome sequence of TMV(TMVSXFQ),
the TMV-SXFQ was gained(GenBank No. JX993906),which was 6 394 bp in length and presented a
typical Tobamovirus genome organization with 4 ORFs.Sequence comparative analysis showed that the homology
of TMV-SXFQ and Tobacco mosaic virus and other isolates was 86.3%-99.6%.Phylogenetic analysis suggested
that TMV-SXFQ isolates had closeer ties consanguinity with IM strain from South Korea and these 2 isolates formed
an independent branch.
